Lately there has been a report on hard-disk failures from Google's own 
system usage.

There is also this abstract from 5th USENIX Conference on File and 
Storage Technologies

Just watch out for those slim sized 3,5" Maxtor disks. Several of the 
20G and 40G models, in a 5-year time span, crashed and burned in 
customers' PCs with 0% data recovery.

Also there has been some problem with SATA cabling (the data cable). 
Brand new SATA2 disks on eight brand new PCs, randomly experiencing slow 
OS boot or reporting problems finding files. Shortly after a disk 
developed bad sectors and noticing similar problems on the other PCs, I 
swapped all SATA cables with different ones. I have yet to hear a complaint.
