Finding UWSCSI drives with termination is difficult. I have a SG with termination and the other end of the chain is terminated with an active terminator; the drive delivers termination power. No problems with the chain - there are total 3 drives.

And you can use 16-bit Synchronous no problem? How much MB/sec transfer rate do you get? (you can measure with SysSpeed).?


Yes - one drive must be forced into it as automatic doesn't work. 28-31 MB/s.

If I remember correctly "Termination Power" is not that big of a thing. You need it somewhere on the bus and (again, if memory serves me right) the CSPPC does that for you.

No it doesn't.

Ultra2 and U160/320 drives do it easily.

This is your problem. I have yet to find any UW scsi device which has built-in active termination - they are all passive in my experience.

Like I wrote Seagate had some models with active term - I have one on my chains end and it works fine. The other end is with an active terminator.
