RAID5 double disk failure, how to recover after data loss

RAID5 because of itself is very few failure, coupled with its own strong fault tolerance, resulting in many enterprises in the data backup is not perfect, which caused the raid data failure is a disaster. Because the relevant recovery technology involves too much knowledge, ordinary administrators and even the server vendor engineers can not solve. This is to provide a feasible solution to the problem of RAID5 double disk failure and data loss recovery.
RAID5 two-disk failure, the individual can take a measure. The first step is to make a full backup of a single disk and make the full backup of each hard disk a separate folder; The second step is to search for the DBR sector; The third step is to determine the file record and check block according to the DBR parameters. Here we need to note that we are not looking for "file records for source files", but "file records for user files". Do not blindly after the operation, direct selection of regular repair channels, such as professional data recovery agencies, so as to effectively ensure that the RAID5 failure problem can be fully resolved, and to ensure the security of the data in the raid. For example, Shanghai's friends will generally choose the Shanghai Day Shield Data Recovery Center.
After the user RAID5 data loss, the day Shield data recovery Engineer will look at the hard disk existing information, through the calculation, to find out the original disk smooth, block size and other related information, manually simulate the original creation of the array state, so as to read all the data. RAID5 data loss, if the user has rebuild reorganization operation, then the original array information will no longer exist, it will not be able to calculate the original parameters, so that the data will not be recoverable, conversely, if not rebuild reorganization and other related operations, RAID5 data recovery can reach almost 100% Success.
Since its inception, the Shanghai Day Shield Data Recovery Center has accumulated a large number of RAID5 array data recovery cases. Here, you can also easily restore data from the following levels of disk array (RAID): RAID0, RAID1, raid0+1, raid1+0, RAID5, raid5+0, raid5+1, raid5+0+1, RAIDADG, RAID6, raid5e, Raid5ee, JBOD, SAN, NAS.
