    I was trying to track the means by which a bad sector is identified and it's elusive as hell. However, in doing all this searching, I got back to reading the original post and I think he wants to know if it's S.M.A.R.T which does this and prevents writing to a bad sector. I can't find the answer to that question. The article at Wikipedia on it, does mention that it's an ATA technology and not all hard drives use it.

    Sectors/blocks are defined by numbers. They most likely have a hash that is read by the drives firmware on it's chip. It's irrelevant. Bad sectors mean 1 thing drive is on it's way out

    I don't agree that a drive with some bad sectors is on it's way out. Never had a hard drive without any. There are a number of tools available to check the status of a hard drive.

    I didn't find anything about firmware on a hard drive. I guess SMART (took out the periods because I'm lazy) is the equivalent of firmware. SMART does log soft bad sectors and I guess hard bad sectors.
