Raid data recovery is somehow different from all other types of data recovery. Most experts advise not to try to recover the data yourself before sending in the hard drives to a data recovery company. This is because most companies found that most of the times simple users try to recover the files all by themselves, they fail and not only. Their actions will make the recovery process even harder and if the lost information is important, someone will be in big trouble. If it's about raid data recovery better handle it quick to the professionals without touching anything.
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.
There are procedures that data recovery companies always follow when they have a recovery on the line. These procedures are followed exactly and even expand when it comes to raid data recovery. As a first step in any raid data recovery, experts have to make sure that all drives are working. For Raid 0 as an example, it is a must for all the drives to be 100% functional. When they are not functional, the drives will be taken in the clean room and will be repaired.
The information involved in such a situation can cost many hundreds of thousands, possibly millions of dollars in labor and resources to create. This is the reason why the executives are not at all interested in finding out the cause of the failure, they just care about the fact that the server has crashed and that the problem must be immediately solved.
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!
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!
