The example error was just one of many. dd crapped out
with:

dd: reading `/dev/hda': Input/output error

Yeah there are a whole list of these, about 70 lines,
most of them seem to be at the same 4 sectors.

I'll back up my stuff, it's not all important. I think
I'll have a look at the returns policy too as it's
only about 5 months old.

Could this have been caused by heat? I lost another
disk around November/December and this was the
replacement. I noticed recently that I was having heat
problems and the disks were just about touchable. the
other problems have been resolved since I took the
side off the case.

What a pain in the arse.

Thanks Ron.
