Thanks Todd for the reply.

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.

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?

The drive is as good as uninstalled, so I may as well send 
it for replacement.

Regards,

Keith

NB: The box is down now, and I'll try and test and identify 
the bad memory module next.
