Strange things with my hard drive

[Kerry Hoath]

Did you make sure that the cable to the hard drive was an 80-wire
udma-66 cable? Compared to the cdrom cable the wires are finer.
UDMA-66 cables are also more springy and less flexible than standard ones.
Even modern burners run at a maximum of udma/33 which doesn't require special cables.
Hard drives on the other hand can run at udma/66 or uata/100 and
failure to use an 80-wire cable with a stupid o/s which fails to disable udma
can and usually does result in data corruption. The operating system in q
question comes from Redmond :-)
Linux shuts down dma if it sees 3 crc errors.
Win 2k and XP are supposed to do this too but sometimes
it doesn't happen.

Regards, Kerry.
