There were no sectors remapped, which is odd as there were bad sectors originally on the drive. I ran MemTest86+ out of curiousity, and there are 5120 Errors, some at 0.4MB& 0.5 MB.
You should fix that first.
Working on that one now ;)
The BIOS has been playing up, not recognising the Primary Master drive. This is the channel the Hitachi disk was on when it developed the sector read errors.
Could a bad controller or bad RAM cause Hard Drive sector errors?
Neither bad RAM or a bad controllor can physically damage a hard drive. A bad controller will not cause reallocated sectors. It can however cause UDMA CRC errors and other weird non-SMART related behaviour.
The drive is as good as uninstalled, so I may as well send it for replacement.
Send the output of smartctl -a /dev/yourdisk, that'll give us more factual data than speculation.
Will do as soon as the memory checks are done, and the machine is up again.
