Could it be possible your Jaz drive is faulty?

hmmm..it does work on its own and it functioned quite recently daisy chained with a tape machine on the Mac so i don't know really.

A quantum tech told me the maximum lenght for a scsi chain is 59''. Although, I think it was QwikSand here who said I'd be fine at 10'. My shortest test configuration where the Jaz failed with one other 50 pin device was a wee bit over 59''. So lenght is certainly a possible area I am looking to improve on.

did you try putting all of your SCSI devices on your 68 pin bus?

The CD and HDD worked ok that way. I could use the one 50 >68 adapter I have to test the Jaz and the HDD together that way. But I have not gone to that extremme at this point. I'll think about that one a bit.

I'd like you to be the first to know that as of 6:22 am EST this morning I am looking at all three scsi devices being shown in my Explorer:))) My SCSI BIOS is enabled AND installed, everything was recognized with no error messages!!! The two 50 pin devices are on their own cable/ribbon and the U2W hdd is alone on its own ribbon.

You'll never guess what the problem was. The longer IDC 50 pin ribbon that I needed to use to reach the inside/outside adapter>the CD>the mobo connector does not have a little key on its female connectors to insure it is being properly orientated on its male counterpart. I simply reversed the connection at the mobo and...bingo! The shorter IDC 50 ribbon I have has this key but was always too short to reach up to the CD then back down to the mobo.

That was a lesson well learned. Hope this simple solution to a nagging problem will be kept in mind by all in the future. ie Don't buy cheap ribbons without an orientation key.
