![]() ![]() Of course there could already be more of the drive unreadable, but having sector 0 unreadable brings the analysis to a halt. One of the big dangers with trying to recover the original drive is that recovery is an intensive process which is likely to cause further harm to a failing drive. Once the drive contents are exactly transferred to a drive which doesn't have a faulty sector 0, it may be possible for recovery utilities to reconstruct the partition table that resides in sector 0, and make the drive accessible. That way the problem can be addressed as a corrupted file system on a sound drive, rather than trying to dodge the problems happening in a faulty drive. The safest approach for a situation like this is to have another good drive available, and image the faulty drive across to the good drive, using a sector-by-sector approach and choosing to ignore errors. ![]() ![]() The biggest problem with sector 0 being unreadable is that it can also be assumed to be unwriteable, so cannot be repaired. As Anshad has observed, low level utilities like Spinrite perform operations on the drive by directly addressing the drive controller hardware, and having the drive attached to the system as a USB mass storage device doesn't give this the best chance of being effective. ![]()
