Hard Disk Data Recovery

Disaster data recovery services, cheap data recovery, data recovery hard drive failure, data processing services disaster recovery, data center disaster recovery plan, crashed hard drive data recovery, hard disk data recovery services, disk data recovery, data recovery, raid5 data recovery.Data recovery after a hard drive failure is the process of extracting data from damaged, failed, corrupted, or inaccessible primary storage media when it cannot be accessed normally. Often the data are being salvaged from storage media formats such as hard disk drive, storage tapes, CDs, DVDs, RAID, and other electronics. This can be due to physical damage to the storage device or logical damage to the file system that prevents it from being mounted by the host operating system. Although there is some confusion as to the term, data recovery can also be the process of retrieving and securing deleted information from a storage media for forensic purposes or spying.

If you have lost data due to hardware failure, virus or other mishap there is still hope. The key is to STOP when you realize what has happened. Every action you take after such an event narrows your chances of recovering your data. There are many data recovery houses that specialize in this type of retrieval.

Remember you may only have one shot at capturing your data if your hard drive crashes. Don't waste that one chance, it might be the only one you have.

Data recovery after a hard drive failure

A wide variety of failures can cause physical damage to storage media. CD-ROMs can have their metallic substrate or dye layer scratched off; hard disks can suffer any of several mechanical failures, such as head crashes and failed motors; tapes can simply break. Physical damage always causes at least some data loss, and in many cases the logical structures of the file system are damaged as well. This causes logical damage that must be dealt with before any files can be salvaged from the failed media.

Most physical damage cannot be repaired by end users. For example, opening a hard disk in a normal environment can allow dust to settle on the surface, causing further damage to the platters and complicating the recovery process. Furthermore, end users generally do not have the hardware or technical expertise required to make these repairs; therefore, costly data recovery companies are consulted to salvage the data. These firms often use Class 100 cleanroom facilities to protect the media while repairs are being made.

 

Despite this, there are many accounts of users getting a bad disk going long enough to pull their data off, often via slightly bizarre tricks. These include making the drive cold (in the freezer) or spinning it manually on the ground, both actions being used to unstick a jammed platter. Most data recovery professionals recommend against the use of tricks such as these, as they can cause additional physical damage to the drive if done improperly (and in many cases, even when done properly).

Data recovery techniques

Recovering data from physically damaged hardware can involve multiple techniques. Some damage can be repaired by replacing parts in the hard disk. This alone may make the disk usable, but there may still be logical damage. A specialized disk imaging procedure is used to recover every readable bit from the surface. Once this image is acquired, the image can be analyzed for logical damage and will possibly allow for much of the original file system to be reconstructed.

Hardware repair

Examples of physical recovery procedures are: removing a damaged PCB (printed circuit board) and replacing it with a matching PCB from a healthy drive (this often entails the movement of a microchip from the original board to the replacement), changing the original damaged read/write head assembly with matching parts from a healthy drive, removing the hard disk platters from the original damaged drive and installing them into a healthy drive, and often a combination of all of these procedures. All of the above described procedures are highly technical in nature and should never be attempted by an untrained individual. All of these procedures will almost certainly void the manufacturer's warranty.

Raid5 data recovery

Raid5 data recovery is serious business as it usually involves a server environment. Contact a data recovery service to help you with this.

Cheap data recovery

Data recovery is not cheap so it all comes down to the perceived value of your own data. Get pricing from a few companies before committing, they could vary greatly. Also ask about charges if they are unable to recover your data. Most hard drive data recovery services charge regardless of whether or not they are actually able to save your data so give this some thought.
