SubjectRe: Corruption Stats: Suggested Blacklist from the data
 # I'd say the starting blacklist should be

# WDC AC22100H
# WDC AC36400L [also 'it work fine' reports too 8)]

'It works fine me for!' ... at least partially. I have two WDC AC36400L
drives in my SMP system:

Linux version 2.1.110 (root@neko) (gcc version egcs-2.90.29 980515

The first one (hda) works just fine with all the bells and whistles turned
on. The second is total trashed by 'hdparm -d1 /dev/hdc' (time-outs,
corruption, etc ...).

They were bought about 2 months apart from each other, so it's possible
that firmware has something to do with it. But if I recall a personal
message from Mlord, he claimed it had to do with my BX motherboard
(Supermicro P6DBE) and the method it implemented the second IDE channel.

# And folks: please send me more reports about corruptions, even SCSI ones now.
# Also if you have a WDC AC36400L send me a Yes/No and also a firmware revision
# (see man hdparm).
