A friend of mine had a dell PC come with an NCR scsi card (can't remember which one). He needed to connect to external and internal harddrives. He was using DOS and Windows (fear and loathing) and he got intermittent read and write errors with both drives connected. With either disconnected it was fine. Both devices were properly terminated. Then in the dell manual in the small print it said 'you cannot connect internal and external drives at the same time'. Incredible?! He got around this problem by installing an additional scsi card.
