usually when a superblock goes bad, it is because the drive was turned off in the middle of some write operations. since there more than one copy of the primary superblock, the filesystem should be recoverable. some orphaned files will be written to Lost & Found for you to look at. If more than one superblock fails, than the problem may be more than filesystem related (such as a hardware failure).
the problem I see here is that the drive is being detected by the system in the BIOS and some of the other utilities appear to see the filesystem. this would tend to suggest that the drive heads are in good shape and the drive controller card if working ok as well. This leaves the drive platters. if they are losing field strength (random demagnetization) that can be very troublesome. it might also explain why it is that frisk sees the partition entries, but the filesystem can't be corrected. mind you, all of what I have said is from the what little I know about the devices themselves. there may be other problems going on that are beyond my current knowledge. -eric On Feb 23, 2012, at 8:53 PM, Michael Havens wrote: > Please, Speculate as to why my superblock went bad. > --------------------------------------------------- > PLUG-discuss mailing list - [email protected] > To subscribe, unsubscribe, or to change your mail settings: > http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss --------------------------------------------------- PLUG-discuss mailing list - [email protected] To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
