This drive connects from the tape drive through a Centronics 50 to
MiniDB50 or HD DB50 (what ever you want to call it) converter.

I know the cabling is perfectly fine. I have a scanner, then a
cdrom drive, then the tape drive, then into the computer. With this setup
everything works fine without a single error. The scanner terminates the
bus correctly, and I have never had any problem with any device. I
replaced the cdrom drive with the cd changer, just swapped them, no cable
changes at all, and I began to get endless errors, and devices failing to
respond. Most of the errors are either "data phase in" parity failures
(tried setting the cd changer drive with dip switches to both parity and
no parity, no change), scsi timeouts (have increased the timeout in the
kernel three fold, no change), and bus resets.

Sorry, I have all of my PCI slots filled up with 2 SCSI
controllers (one for fast devices, one for normal, external scsi devices),
a NIC, and a video card. I am trying to get away from IDE. If this cd
changer will not work with Linux, just tell me and I will take it back. I
just bought it becuase it was at a good price and might be nice for
playing audio CDs. Thanks for the help.
