Could you give the kernel options used when you boot up? Do you know that the drive isn't bad?
You might want to indicate your disto and kernel version. If the other drives are the same, or use the same controller, then since they are OK, you aren't using a kernel boot option that might cause problems, such as with interupt sharing, and the kernel driver doesn't have a problem as the other ones are OK. You might consider purchasing SpinRite from www.grc.com. It may be able to recover the disk if it's bad. |
Do you know that sdc is supposed to have something on it?
What piques the curiosity is that it seems to be looking for--e.g.--sector 104857584. I don't know why it would do that unless it found something in the primary partition table that pointed there. If this drive has data that you need to recover, then be careful not to do anything that would write to the drive. If there's no concern about what's on the drive, then just re-partition it. |
