Raid Data Recovery : What and How On Raid Data Recovery

August 28, 2008

When it comes to the recovery of data from a hard disk, the best option for any firm is to use the Raid data recovery method. It is a very complex process that tries to repair the damage done by the client before sending the hard disk to the data recovery firm. It is never advisable for a user to try and recover the data himself. These clients may use certain system utilities tools in order to repair the array, but they may very often cause even more trouble. And, as when things go bad, they usually do when the data is critical, these hard disks should be directly taken to a firm that is specialized in data recovery.

For example, previous happenings have showed that, when a RAID failure occurs and results in the loss of important data, somebody’s job is on the line! If the data is not recovered, then things get quite complicated, for the employee, as well as for the employer.

RAID 0 is simply striping the data across multiple disks. It’s like dividing the data into smaller pieces of fixed size, called the “stripe width,” and writing the stripes across the disks. If the file to be written was 5KB in size, with a stripe width of 1KB and there are 4 disks to a RAID set, the first stripe would be written on the first disk, the second on the second disk, and so on up the fourth stripe, the fifth stripe is written to the first disk. This is a fast way of writing large files but if one disk fails, the whole set fails.

When all the drives will function normally, clones of all the drives will be made. During this process, your drive will be placed in a write protect mode to make sure the data will not be altered in any way. The normal recovery process will be performed on the cloned drives, again, for increased safety.

It is true that the Raid data recovery process can be pretty expensive, but in most cases it is nothing compared to trying to recreate the data that has been destroyed. Not to speak about the fact that getting the data back could be enough to save someone’s job!

Even if raid data recovery sometimes can become expensive, most companies will not charge you for an evaluation of a complex raid system. If you need the help of the experts, get it, it’s the best way. After getting all your data back, make sure to always backup your information from now on.
