Case:
The customer took two Fujitsu SCSI68 stitches MAP3735NP 73GB hard disk, saying that it was removed from the server, and the data in the hard disk was restored.I asked a technical maintenance person to test before, thinking that the SCSI card was damaged.After changing a good SCSI card, it was still the same.After that, two good SCSI hard disks were replaced and found that the original SCSI card can be recognized to the hard disk model.It should be that the two SCSI hard disks are damaged (as to how to set the array information, whether it is RAID0 or group RAID1, the customer said it is unclear).
Solution:
The engineer of the Data Recovery Center first detects failure such as burning and overcurrent of the hard disk circuit board. The professional equipment PC3000 SCSI is used to detect it. It is found that a SCSI hard disk has a small physical badway. The other SCSI hard disk does not recognize the disk.lead to.The engineer of the Data Recovery Center uses professional equipment PC3000 SCSI to use the SCSI hard disk with physical bad sectors as a mirror.The hard disk also has a physical bad duct, and also uses professional equipment PC3000 SCSI for full mirror image.After the mirror, the array structure analysis of the bottom layer of the two mirrors was analyzed by Winhex. It was found that the array used the NTFS storage structure to form RAID1.EssenceAt this point, the data recovery is completed.
