Overview About Raid Data Recovery
With the cost of hard disk falling, it is not uncommon for home desktop PCs to have RAID. In fact, most PC motherboards have a built-in RAID controller, even if it is not in use. RAID is short for “redundant array of inexpensive disks” and was developed to use smaller disks in an array for better performance, scalability, and data reliability and recovery.
You don’t have to take chances with the recovery, it’s advised to research for a data recovery company that can handle the recovery process for you. Sometimes, it can be expensive for a raid data recovery but usually the price you will have to pay for the recovery is way lower then the price you will have to pay in time and resources to have all your data recreated.
Therefore, the best action you can take in the situation of a Raid data recovery problem is to immediately send the hard disk to a specialized firm. Should a serious system failure occur, the whole pressure is transferred to the hard disk data recovery professionals. As the users are in the habit of starting troubleshooting processes in order to solve the problem, the data recovery experts must also repair the damage done by these processes, as they can make the data impossible to recover.
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.
RAID 0 1, is a combination of RAID 0 and RAID 1. The data is striped across disks first, and then mirrored across the same number of disks. If you have four disks, the data is striped across the first two, and then the pair is mirrored across the remaining two disks. This is a robust solution but very expensive.
The procedures that Raid data recovery consists of start by making sure all of the drives are properly functioning. This may mean taking the physically damaged drives into the clean room and try to make all the necessary repairs, in order for them to normally function again. The hard disk data recovery technician then initiates a very low-level process that allows him to work around bad sectors of the disk. It is in fact making complete sector-by-sector clones of every drive. The original source drive is being put in a “write protect” mode, in order to protect the existing data during the cloning process. The actual recovery process is performed on these cloned copies!
