Options For Hard Drive Data Recovery

It is important to appreciate the fact that all hard drives crash eventually. You may have a hard drive crash and you may need some professional help so as to retrieve the data within. There are different ways in which you can recover data regardless of how bad the situation is.

People don’t like losing files completely. When such a thing happens to you, there is a need to make an informed decision and find out as much as you can regarding data recovery. You need to make sure that you are given the task of recovery to someone that you can trust and someone that is qualified to handle such a task without completely destroying the information. Data recovery is the process that is used to acquire usable data from the hard drive sometimes the lost data could be very important and without it business can actually fall.

The data recovery companies

Data recovery companies should be advanced technologically so as to be able to handle such tasks with the greatest ease. They can be able to recover the data from storage devices, corrupted media, damaged media, downed media as well as inaccessible media.

One very important component of such companies is the staff. It is essential that they have recovery technicians that have the knowledge and expertise to handle the issue. They should also be able to use result oriented and the latest data recovery software as well as disc recovery tools so as to recover the data that has been lost. These are people who should be in a position to recover lost data even when the situations are critical and hope minimal.

What causes data loss?

There are many ways in which you can lose your hard drive data. The mist common data loss cause is virus attacks. Other cases include technical problems, hardware failures, software failures, human errors and so on. When such things happen, you can lose very personal and important collections like files, photographs and so on. It can also lead to delay of projects, loss of confidential data, and even losses affecting the business if any.

Another scenario in which data recovery could be required is where the operating system fails. In such a situation, the main goal is to copy all files that are wanted somewhere else. This is something that can be done with great ease by the data recovery specialists. In such a case, the system drive as well as backup discs or the removable media is mounted and then files moved into the backup using optical disc authoring software or a file manager.

Data recovery can also include the recovery of office files, photos, deleted files, backup recover and even email recovery. It is essential that the companies that handle such matters have technicians, that are able to handle very sensitive needs. Confidentiality is a very important thing.

It is essential that you only seek the services of persons highly qualified in the area since they can be able to determine the damage, where the problem originates and just how much of the data can be extracted. Serious failures may involve some disassembly as well as manual repairs.

There are many ways of dealing with data loss. The hard drive is sometimes affected and it may have some very critical information that we can’t afford to lose. Hard drive data recovery Utah and salt lake city data recovery allow you to gain access to your data once more even when you had lost all hope.

5 Data Recovery Tips

There is no doubt that our lives have become a lot easier because of technology. Nowadays, we have a lot of up-to-date and automated ways of doing things. For instance, today, we can store a huge amount of data on small chips called memory cards. And the chances of data loss are not so high. Even if we lose data, we can get it recovered with a few clicks of the mouse. Read on to know 5 data recovery tips.

Make a Recovery Plan

If you have a plan, you won’t panic in case something goes wrong. For data recovery, you can choose from a lot of free tools as they are designed specifically for this purpose. So, what you need to do is install a good app ahead of time. You can also hire one of the best data recovery services, but it may cost you more.

Use Flash Drives

Ideally, it’s a good idea to create a back up of your important data. You can store your backup on a flash driver, for instance. And if your hard drive fails, you can get your data back within a few minutes.

Cloud Storage

With cloud storage, you can store your data in a separate location. This is one of the many reasons cloud storage is increasing in popularity. This place won’t be touched by your failed hard drive, flash drive or other data storage units. This is the reason most of cell phone service providers offer cloud storage. As a matter of fact, cloud storage is one of the best ways of preventing data loss.

Recovery of deleted files

Keep in mind that most files that get deleted can be recovered provided you can use the right tool. But if the files have been shredded or deleted permanently with a special data deletion tool, then you can’t do anything. This means that if you have deleted some files and they are lying in your recycle bin, you can get them recovered.

Looking for Lost Data

If you want to recover data, you should first find out a way of searching for the data. But this task requires a lot of patience even if you use an app to perform the search for deleted or lost files. So, if you have a huge amount of data to recover, we suggest that you let the professionals handle the job, especially if the data is really important to you. Usually, hiring professionals is a great idea if your business data is at stake.

Keep in mind that you may need to recover data no matter how cautious you may be. Actually, the idea is to get ready and find out what to do when data loss happens. With technology, our lives can become a lot easier and convenient. As far as data loss goes, we suggest you stay prepared at all times and use the best tools that are at your disposal. This way you can rest assured that lost data would be recovered safely.

What Are the Different Methods Used for Data Cleansing?

What is data cleansing and why is it important?

Having an updated database is a vital requirement for organizations these days, given that most of the business comes through marketing. An updated database will ensure that the contacts are correct and you can connect with the customers efficiently while keeping up with the compliance standards. Now, with everyday use by different team members there are high chances of the data getting corrupt (incorrect or jumbled up). It is also a possibility that some contacts may become obsolete over the time and needs replacement.

That is where data cleansing comes to rescue, since with this process you can ensure that you identify any inaccurate data and consequently correct them. Therefore, the data cleansing process aims to maintain clean (steady and correct data) customer database by finding out any inaccurate data (incorrect, obsolete, or incomplete) and remove the dirty data thereby, creating a single record for individual customer with all of their related information. While manual maintenance is usually followed, using the data cleansing tools is also picking up pace these days due to the complexity the database administrator has to face. Before we discuss the different methods used for data cleansing let’s see why cleaning data and maintaining an accurate customer database is so important.

1. Keeping up with the compliance standards that is, Data Protection Act is an important aspect for any organization and so, the data cleansing plays a vital role here.

2. Cleaning data on a regular basis ensures that there’s minimum wastage of information, that is, less wrong emails. This automatically cuts down the mailing costs thus, help your business save some resources.

3. Customer data is crucial for any business and so, you must make sure to maintain a clean database that enables quick repair of customer information thus, lowering the turnaround time.

4. Having all data at one single place not just enhances the quality of service, but also offers improved customer experience.

5. Marketing your business to potential clients is the major survival strategy for all enterprises, and so, a clean customer database will ensure that you have correct client information helping to generate better sales targets and proper management.
That being said, it’s still a tough task to manage a clean customer database.

Customer information keeps changing frequently and so, get obsolete very soon. Moreover, the customer databases in many businesses may have multiple information based on different parameters such as, buying history, list of prospects, or email list. This can create a lot of confusion and mix up since the details of the same customer may appear on different databases with fragments of significant information under each parameter.

So, if you are asking for the methods used to clean data, it’s important for you to know that that it entirely depends on the different software used by the business like, the type of CRM, marketing automation and any other software that you are using. Irrespective of the method you choose, it’s usually a lot challenging to clean data manually as it will consume a lot of time and efforts that directly affects the overall productivity of the company. But, if you are looking for a specific method, you would first need to identify the type of data clean-up you want to perform. The method adopted would totally depend on whether you want to append data, remove duplicate entries, standardize data, delete non-usable contacts, verify the email list, and so on. And, that’s the

Therefore, your life is much easier when you outsource the data cleaning process and seek help from different data cleansing tools available in the market. Data Ladder is one such efficient tool that’s known for it advanced semantic technology that helps maintain the customer database by removing any unwarranted errors or duplicate entries that might be creating all the confusion. It therefore, reduces the time spent on the entire data cleaning process and cuts down costs considerably thus, helping to improve the productivity of the company.

Methods used for data cleaning:

Reviewing Data
The cardinal step for data cleaning, should always be to review the customer databases completely right at the start. Check any deviations or inaccurate data by analysing/auditing the database with the help statistics and database techniques. The data generated via these methods should then help you to figure out the location and attributes of the deviations helping you to reach the root of the problem.

Employing different methods
The reviewing of the database should not be restricted to just using the statistical or database techniques. The reviewing process must also include methods like purchasing data from outside and then analyse it in comparison to the internal data. But, if that does not suffice and the enterprise is facing a challenge with limited staff and time, use of an external telemarketing company is a better idea. However, here it’s important for the company to be careful about their brand image and the work standards followed by the external organization (third-party).

Data integration
Data cleaning is not just about finding and deleting inaccurate data from the customer database, but it should be rather used to the company’s advantage to integrate customer information and added details such as, phone numbers, email address, or any other contacts time and again.

Reporting of information
Businesses must ensure that there’s a robust management system within the organization that can timely and effectively identify and report any incorrect data and it’s update in the database. This can be achieved by a managed and feedback system intended for emails and any email that bounced back because it was not the right address. This anomaly should be reported and the incorrect email address should be removed from the customer database.

Repeat the same process
It’s a constantly progressive world where everything is changing so fast, that businesses must be able to keep up with the fast pace and so, customer data like, company email address, phone numbers, mailing addresses, etc. change very often. Therefore, simply running a one-time data cleansing process would not be the solution and thus, repeating the same data cleansing process on a regular basis is extremely important. Filtering of such inaccurate data and update of the customer database on a regular basis is the only way out to make sure that the company has a clean database.

Yes, data cleansing is a major process that is critical and time consuming. Given that it requires a lot of time, effort and resources, it is a wise decision to use the reputed data cleansing tools available these days. Using data ladder for de-duplication or managing customer database along with cleansing is one of the best ways to keep clean records and ensure consistent growth of the company.

Top Ways to Prevent Data Loss

Data loss is crippling for any business, especially in the age of big data where companies rely on digital information to refine their marketing, contact prospects, and process transactions. Reducing the chances for data loss is a vital part of a data management strategy.

The first goal should be to prevent data loss from occurring in the first place. There are many reasons which could lead to data loss. A few of them are listed below:

1) Hard drive failures

2) Accidental deletions (user error)

3) Computer viruses and malware infections

4) Laptop theft

5) Power failures

6) Damage due to spilled coffee or water; Etc.

However, if a loss does occur, then there are several best practices you can implement to boost your odds of recovery.

Secondly, don’t put all your storage eggs in the cloud basket. The cloud is vital for cost-effective storage, but it does have some pitfalls that shouldn’t be ignored. Many examples of data loss have occurred from an employee simply dropping their computer or hard drive, so talk to staff members about best practices. SD cards are much more fragile and should never be used as a form of longer-term storage.

Here’s a look at top ways you can protect your data from loss and unauthorized access.

Back up early and often

The single most important step in protecting your data from loss is to back it up regularly. How often should you back up? That depends-how much data can you afford to lose if your system crashes completely? A week’s work? A day’s work? An hour’s work?

You can use the backup utility built into Windows (ntbackup.exe) to perform basic backups. You can use Wizard Mode to simplify the process of creating and restoring backups or you can configure the backup settings manually and you can schedule backup jobs to be performed automatically.

There are also numerous third-party backup programs that can offer more sophisticated options. Whatever program you use, it’s important to store a copy of your backup offsite in case of fire, tornado, or other natural disaster that can destroy your backup tapes or discs along with the original data.

Diversify your backups

You always want more than one backup system. The general rule is 3-2-1. You should have 3 backups of anything that’s very important. They should be backed up in at least two different formats, such as in the cloud and on a hard drive. There should always be an off-site backup in the event that there is damage to your physical office.

Use file-level and share-level security

To keep others out of your data, the first step is to set permissions on the data files and folders. If you have data in network shares, you can set share permissions to control what user accounts can and cannot access the files across the network. With Windows 2000/XP, this is done by clicking the Permissions button on the Sharing tab of the file’s or folder’s properties sheet.

However, these share-level permissions won’t apply to someone who is using the local computer on which the data is stored. If you share the computer with someone else, you’ll have to use file-level permissions (also called NTFS permissions, because they’re available only for files/folders stored on NTFS-formatted partitions). File-level permissions are set using the Security tab on the properties sheet and are much more granular than share-level permissions.

In both cases, you can set permissions for either user accounts or groups, and you can allow or deny various levels of access from read-only to full control.

Password-protect documents

Many productivity applications, such as Microsoft Office applications and Adobe Acrobat, will allow you to set passwords on individual documents. To open the document, you must enter the password. To password-protect a document in Microsoft Word 2003, go to Tools | Options and click the Security tab. You can require a password to open the file and/or to make changes to it. You can also set the type of encryption to be used.

Unfortunately, Microsoft’s password protection is relatively easy to crack. There are programs on the market designed to recover Office passwords, such as Elcomsoft’s Advanced Office Password Recovery (AOPR). This type of password protection, like a standard (non-deadbolt) lock on a door, will deter casual would-be intruders but can be fairly easily circumvented by a determined intruder with the right tools.

You can also use zipping software such as WinZip or PKZip to compress and encrypt documents.

Use EFS encryption

Windows 2000, XP Pro, and Server 2003 support the Encrypting File System (EFS). You can use this built-in certificate-based encryption method to protect individual files and folders stored on NTFS-formatted partitions. Encrypting a file or folder is as easy as selecting a check box; just click the Advanced button on the General tab of its properties sheet. Note that you can’t use EFS encryption and NTFS compression at the same time.

EFS uses a combination of asymmetric and symmetric encryption, for both security and performance. To encrypt files with EFS, a user must have an EFS certificate, which can be issued by a Windows certification authority or self-signed if there is no CA on the network. EFS files can be opened by the user whose account encrypted them or by a designated recovery agent. With Windows XP/2003, but not Windows 2000, you can also designate other user accounts that are authorized to access your EFS-encrypted files.

Note that EFS is for protecting data on the disk. If you send an EFS file across the network and someone uses a sniffer to capture the data packets, they’ll be able to read the data in the files.

Use disk encryption

There are many third-party products available that will allow you to encrypt an entire disk. Whole disk encryption locks down the entire contents of a disk drive/partition and is transparent to the user. Data is automatically encrypted when it’s written to the hard disk and automatically decrypted before being loaded into memory. Some of these programs can create invisible containers inside a partition that act like a hidden disk within a disk. Other users see only the data in the “outer” disk.

Disk encryption products can be used to encrypt removable USB drives, flash drives, etc. Some allow creation of a master password along with secondary passwords with lower rights you can give to other users. Examples include PGP Whole Disk Encryption and DriveCrypt, among many others.

Make use of a public key infrastructure

A public key infrastructure (PKI) is a system for managing public/private key pairs and digital certificates. Because keys and certificates are issued by a trusted third party (a certification authority, either an internal one installed on a certificate server on your network or a public one, such as Verisign), certificate-based security is stronger.

You can protect data you want to share with someone else by encrypting it with the public key of its intended recipient, which is available to anyone. The only person who will be able to decrypt it is the holder of the private key that corresponds to that public key.

Hide data with steganography

You can use a steganography program to hide data inside other data. For example, you could hide a text message within a.JPG graphics file or an MP3 music file, or even inside another text file (although the latter is difficult because text files don’t contain much redundant data that can be replaced with the hidden message). Steganography does not encrypt the message, so it’s often used in conjunction with encryption software. The data is encrypted first and then hidden inside another file with the steganography software.

Some steganographic techniques require the exchange of a secret key and others use public/private key cryptography. A popular example of steganography software is StegoMagic, a freeware download that will encrypt messages and hide them in.TXT,.WAV, or.BMP files.

Protect data in transit with IP security

Your data can be captured while it’s traveling over the network by a hacker with sniffer software (also called network monitoring or protocol analysis software). To protect your data when it’s in transit, you can use Internet Protocol Security (IPsec)-but both the sending and receiving systems have to support it. Windows 2000 and later Microsoft operating systems have built-in support for IPsec. Applications don’t have to be aware of IPsec because it operates at a lower level of the networking model. Encapsulating Security Payload (ESP) is the protocol IPsec uses to encrypt data for confidentiality. It can operate in tunnel mode, for gateway-to-gateway protection, or in transport mode, for end-to-end protection. To use IPsec in Windows, you have to create an IPsec policy and choose the authentication method and IP filters it will use. IPsec settings are configured through the properties sheet for the TCP/IP protocol, on the Options tab of Advanced TCP/IP Settings.

Secure wireless transmissions

Data that you send over a wireless network is even more subject to interception than that sent over an Ethernet network. Hackers don’t need physical access to the network or its devices; anyone with a wireless-enabled portable computer and a high gain antenna can capture data and/or get into the network and access data stored there if the wireless access point isn’t configured securely.

You should send or store data only on wireless networks that use encryption, preferably Wi-Fi Protected Access (WPA), which is stronger than Wired Equivalent Protocol (WEP).

Use rights management to retain control

If you need to send data to others but are worried about protecting it once it leaves your own system, you can use Windows Rights Management Services (RMS) to control what the recipients are able to do with it. For instance, you can set rights so that the recipient can read the Word document you sent but can’t change, copy, or save it. You can prevent recipients from forwarding e-mail messages you send them and you can even set documents or messages to expire on a certain date/time so that the recipient can no longer access them after that time.

To use RMS, you need a Windows Server 2003 server configured as an RMS server. Users need client software or an Internet Explorer add-in to access the RMS-protected documents. Users who are assigned rights also need to download a certificate from the RMS server.

The Answers to Effective Management of Exponentially Growing Healthcare Data

Healthcare systems are generating more patient data than ever before. With the progression of diseases, the “data footprint” of each patient increases over time, thereby increasing the overall amount of data, which the appropriate bodies (mostly health care providers) must manage.
Large amounts of data are inherently difficult to manage, but an abundance of data also means that better analytic results can be derived, which is necessary to drive lower cost and better patient outcomes. Consequently, there is a huge demand for data management platforms in healthcare and allied industries for efficiently storing, retrieving, consolidating, and displaying data.

A Vendor Neutral Archive (VNA) is an integral component of modern health data management. A VNA is a storage solution software that can store images, documents, and other clinically relevant files in a standard format with a standard interface.

Data stored in a VNA can be freely accessed by other systems, regardless of those systems’ manufacturers. This interoperability is a hallmark of any VNA system. The term “Neutral” in the acronym VNA has huge implications, as it makes the data stored in VNA, platform-independent. VNAs make it easier to share data across the healthcare system, facilitating communication between departments. They enable imaging clinicians to use software that integrates images with the EHR, in order to help make better-informed diagnoses.

A VNA can also help make data more secure. VNAs that use cloud-based storage can offer better recovery options than a local-only solution. Even if the local files are corrupted or destroyed, the data remains intact in a secure location through a cloud server.

Another hidden advantage of VNAs is the lowering of administrative costs. Fewer systems and fewer points of access mean less overhead for the IT department. And there is no need to migrate data when systems are updated or replaced, a procedure that can be resource-intensive. VNAs potentially offer lower storage costs, as compared to separate PACS systems, throughout the healthcare system as well. VNAs can use information lifecycle management applications to automatically shift older data to less expensive long-term storage, keeping only the most used data on higher-cost quick-access media.

Implementing a VNA is a major shift in a healthcare system’s operating procedures. This shift can uncover a multitude of opportunities to increase efficiency, streamline workflows, and lower costs.

Modern diagnostic practices generate an enormous amount of pictures and pictorial data. PACS stands for Picture Archive and Communication System. The main purpose of PACS is to simplify the management of images related to patient monitoring throughout the treatment and recovery. Modern radiology practices involve digital imaging. Therefore, for the purpose of interoperability, a standard is required, which is identified by all the stakeholders and is accepted as a norm.

The case in point is DICOM, which stands for Digital Imaging and Communications in Medicine. PACS that adhere to DICOM standards are better suited to accommodate digital image data generated through medical devices procured from different vendors. In other words, DICOM-compliant PACS have better interoperability and a wider coverage for storing and processing different types of digital images generated through varied medical procedures.

The conventional advantages of PACS include duplication removal, quick access of patients’ images and reports, remote sharing of patient’s data and reports within an organization or to other organizations, and the establishment of chronology in patients’ radiology results, in order to facilitate comparison with previous studies on same or other patients.

With a multitude of vendors offering enterprise image management systems, it becomes difficult to make the best choice. Each organization is different in terms of organization hierarchy, as well as the type of network used for communication and financial constraints. Consequently, the requirements for enterprise imaging solutions for each one of these will be different, and no one vendor alone can satisfy all of these demands.

GE Healthcare and Philips offer some of the most exciting PACS solutions. These two vendors have a unique distinction of having a global clientele and providing enterprise archive-centric strategies. An enterprise archive refers to long-term storage for managing and collecting data from multiple imaging departments.

If organization’s needs are more VNA-centric, then vendors with exclusive VNA expertise should be considered. An example of a VNA-centric expert would be Agfa. Agfa provides VNA solutions at the enterprise level for handling both DICOM and non-DICOM data.

Irrespective of the size of one’s facility or a number of patients one has contact with, you need to make image storage a necessity, because physicians require a seamless access to them. As a thumb rule, it is imperative to say that any large organization with dedicated departments for various diagnostic imaging (or at least a dedicated radiology department) should have a PACS system in place. If financial constraints are not in place, then a hybrid system incorporating both VNA and PACS should be used for cloud-based storage. Hybrid systems with cloud-based storage are considered to be one of the most efficient modalities in current enterprise imaging management.

Two Reliable Methods To A Secure Data Destruction

Today, the mode of work has changed from keeping information in hard from to soft form. Every kind of business needs a secure network to keep its data safe. Firms spend millions of dollars on IT services to maintain their records on hard disk. Nowadays, cloud computing is also being used for preservation of sensitive files instead of desktops. But, failure to comply with the requirements of security can lead to very serious repercussions for the business. Breaches of privacy, data protection, compliance issues and additional costs occurs due to improper data destruction services.

Here comes the great importance of protected hard drive disposal services. Not all the companies opt for cloud computing, which itself is also not a highly secure facility either. Majority of the online firms utilize the common source of record keeping, i.e. on PCs. Keeping the online files intact is one thing, but having to get rid of the information which is no more needed is another. Therefore, companies look for hiring the services of experts in the field of data disposal services without breaches.

Following are the two reliable methods to accomplish secure data destruction:


One method of secure hard drive disposal includes is to overwrite all the information present on hard disk with new one. It is considered to be a very economical mode of data destruction. All you have to do is get an overwriting software that can be applied on part or entire hard drive. If you have already addressed all the regions of data storage, then you just require a single pass for successful removal of stored files. You could configure the overwriting application to select specific files, free space or partitions present in hard drive. All the remnants of data are positively deleted after overwriting in order to ensure complete security.

Be that as it may, the process of replacing information on entire disk is a lengthy process to achieve. It could also not achieve removal of files present on host-protected folders. The process could be victim to data theft during the overwriting procedure due to changes in parameters. Secure hard drive disposal can only be accomplish while it is still in writable condition and not damage in any way.


Unlike overwriting which is done by a software, degaussing involved the usage of a specific device known as Degausser. Hard Drive Disposal and other services highly recommend this method of data destruction. Degaussing is actually the practice of reducing magnetic field of a hard disk. By doing so, it can eliminate all files present on storage medium like floppy disk, CD, DVD, or any other kind of hard drive. One of the major advantages of this method is that it completely removes the information making it impossible to recover data.

However, highly effective degausser devices can be very costly to purchase. They are also extremely heavy to maintain. It can also cause malfunction of nearby vulnerable instruments due to its strong electromagnetic fields. In addition to that, hard drives can get permanent damage in the process.

To sum up, secure data destruction for a large sized online company can be a very tricky task to achieve. Overwriting and Degaussing are more trustworthy means of achieving that. Though, one can also look up for some other methods as well. It depends on the nature of one`s needs and financial resources. If you have a small to mid-size firm, then you could opt for Overwriting. On the other hand, if you have got a large company, Degaussing would be the most suitable choice.

How to Recover From a Hard Drive Failure

Unfortunately, most home users, and many business users, do not back up their systems. Moreover, many small businesses have older back-up procedures that are often ineffective for recovering files.

Of course, you can run down to your neighborhood electronics store and purchase a replacement drive for your computer, but what about your data on the failed hard drive? How important was it? Did you save it or back it up?

What to do:
If you need to recover data on the hard drive, the first thing to do is avoid trying to reboot or doing anything that involves the drive. Doing so can actually do more damage to your data.

The only irreversible data loss is caused by overwriting bits, physical damage to the drive platters or destruction of the magnetization of the platters, which seldom happens in the real world. In the majority of cases, the malfunction is caused by a damaged circuit board, failure of a mechanical component and crash of internal software system track or firmware.

In the case of actual hard drive failure, only a data recovery professional can get your data back. And the fact that you cannot access your data through your operating system does not necessarily mean that your data is lost.

As a “rule of thumb,” if you hear a clicking sound emitting from your hard drive, or if the computer’s S.M.A.R.T. function indicates an error during the boot process, something is wrong. You should immediately stop using the hard drive in order to avoid causing further damage and, potentially, rendering the information on the hard drive unrecoverable.

After receiving your failed hard drive, a data recovery specialist’s first step will be to try and save an image of the damaged drive onto another drive. This image drive, not the actual damaged drive, is where the data recovery specialist will try to recover the lost data.

The next step in the imaging process is to determine if the hard-drive failure was an actual malfunction, a system corruption or a system track issue.

System corruption and system track issues are normally fixed by using a specialist’s data recovery software. System corruption or system track recoveries do not require processing in a clean room environment.

Unfortunately, damage to a drive’s circuit board or failure of the head drives is not uncommon. In each of these failures, a data recovery specialist should work on the system only in a clean room environment. There, the specialist can substitute parts such as drive electronics, internal components, read/write arms, writing/reading heads, spindle motors or spindle bearings from a donor drive in order to gain access to the data on the failed hard drive. In most cases, the data recovery specialist is able to retrieve and return the lost data.
