Data recovery engineer testing, there is a hard disk with a bad disk and cannot be read.After verification calculation, calculate this hard disk data, and virtually produces all parameters such as RAID block size, pan -smooth, and direction.Restore the data successfully.The whole process was only two hours. After confirming the customer technology, the two hundred databases were completely complete without any damage.Data recovery successfully.
