(Complex data recovery with low success rate in this case) If the number of damaged disks exceeds the limitation, RAID data cannot be read.
RAID usually consists of a few disks, and allows limited number of damaged disks (for example, RAID5 allows one damaged disk). (High data recovery success rate in this case)ģ. RAID disks have bad sectors, and thus causes data loss. RAID disks report errors with flashing red light, detection error on HDD.Ģ. Accidental deletion/formatting/partition/clone, file decoding, virus attacks, etc. Wrong disk order causes system unable to recognize the data.Ĥ. A sudden power outage causes data loss on RAID card.Ģ.

There are many causes of RAID data loss, commonly divided into two broad categories: Software Failure and Hardware Failure:ġ.Some servers will perform automatic initialization after reconfiguration, and this will lead to unrecoverable data loss. Be cautious about reconfiguring disk arrays.Initialization is to reset disk array, which is the same as low-level formatting of hard disks. This will increase difficulty of data recovery. Do not rebuild RAID card incautiously, for it may cause data loss and thus some files can’t be opened.This reduces the risk of further damage to the data. Once data loss occurs, avoid any operation on disks, remove disks from RAID card in order (mark the disk order correctly), create a disk image file for each disk with Disk Imaging Software, and recover data from disk image files, rather than disks.
