I don't know what the problem is, I would have expected the drive to 
report errors in it's log if it is genuinely failing (I've seen this on 
my laptop)

Have you tried running SMART tests on the disk?

I'm not saying SMART is the be all and end all of failure monitoring but 
it has indicated problems to me in the past :)
