If it's anything like the Compaq SMARTArray failures I've seen, the 
problem was EMI on the Proliand drive bay backplanes that made the 
controller receive garbled data, so it declared the disks bad, even 
though they were perfectly fine.  We had Compaq go and manually reset 
the disks to "good" status - using proprietary hardware - to recover 
some of the data after we had threatened to take our business elsewhere 
since we had had 7 or 8 RAID array failures in less than a month.

They also replace all our Proliant drive bays (60 of them, across North 
America) for a more recent revision number of the backplane.  Our 
carefull inspection revealed the "Rev. D" boards had two extra 
capacitors, and a huge ferrite core around the SCSI cable.
