  Well, remove the CD from the chain. If the problems go away, then you
either have a termination problem, or a SCSI ID conflict. Note that
the inverse of 6 is 1 - and people who put together enclosures
often reverse the SCSI ID switch connector, making the true SCSI
ID the inverse of what the switch says. Use the RamFAST utility
program to verify the true SCSI ID number of your hard drive and
CD-ROM drive. Power each on individually and use the RamFAST utility
to check the SCSI ID.

  Personally, it sounds like a SCSI ID conflict.
