Case:
The server HP MSA1000, the RAID ADG composed of seven hard disks, and the operating system is Win2003. In advance, it is found that the system prompts $ MFT errors. It is required to run the CHKDSK command for repair.However, the administrator did not care. Suddenly one day, one day found that the No. 2 plate on the array was bright red, so it pulled off the No. 2 disk and replaced the No. 2 disk with a new disk.Data recovery center help.
Solution:
According to the analysis of the underlying data of the Data Recovery Center, it is found that the position of about 15GB of each disk is the same as the position of the redundant information of the No. 2 and 7 disk.After 15GB, the data combination method is in line with RAID ADG.The cause of this result may be: After changing to the new plate, the system uses the No. 2 market as 7, and uses the rest of the disk to reBuild; or the 7th plate has fallen.Come on the market to reBuild; or the position 2 and No. 7 are physical replaced by the position, etc., and then it is caused by other series of operations after the problem.We use the “escort ship”” to reorganize according to the data portfolio after 15GB of each disk. The result of the recovery is that the data directory structure is chaotic
