So back it up and think of maybe replacing the disk (but also think of other sources of the problem, e.g. dodgy RAM, disk controller or motherboard, since these can write corrupt data to the disk).
The Smartmon tools are talking directly to the firmware on the drive, it is this firmware that has recorded and reported the error. It's not the same as a filesystem error and in this case cannot be caused by RAM, disk controllers, cables or motherboard.*
I get what you are saying though, filesystem errors can be caused by all the things you mention but in this case the error has been detected by something that is running at a raw hardware level and isn't even aware of the filesystem on the disk.
- Well actually that's not strictly true, powering down the drive in
the middle of a write could make it think it has a bad sector, but given the write speed of a modern drive I don't think it is at all likely on modern hardware.
Thanks for the clarifications, Wayne -- as I said, I'm not familiar with SMART stuff, so was to an extent guessing. I'm sure your spelling out of where the messages came from will help Barry!
Cheers, Ted.
