[Nottingham] data transfers causing hard hangs

[Jim Moore]

Sounds like an ATA controller problem. Have the drives checked. I've 
sometimes found RAM problems as well can cause such behaviour, so it'd 
be worth doing a burnin test on that (not the usual Memtest86 one, try 
the Microsoft Memory checker; it's much more thorough, or QuickTech Pro 
if you can lay your hands on a copy (QTP also does drive testing so 
that's a good all-round solution)). Incidentally, what cooling do you 
have in place for the drives?
