Re: Strange goings on with a SATA drive on XP
I would be more inclined to think it's an incompatibility between Mobo (ATA controller) and SATA card. At the time it dies you are pumping large amounts of data down the ATA channel and up the SATA channel. I'm not an expert on electronics, but I wouldn't think there would any sigificantly different power usage betwee an idle and busy drive and the PSU is able to boot up with all the drives.
The only thing I would suggest at this point is booting of the SATA with both disks plugged in and verify that the same thing happens during the copy. XP 'shouldn't' overwrite anything on the IDE drive.
