Re: Adaptec 39160 RAID ?!

Yes, but doesn't the card ship with "fake RAID"?

No, it's just a plain old Ultra160 Dual Channel SCSI Host Adapter.

I just purchased one actually, have hooked it up to a Quantum Atlas 10K2 
and can't seem to get them talking in Ultra160 mode.  Here's the proc 
output:

The drive has a SCA connector on the back, with a sticker on the connector 
stating "Ultra160/LVD/SE".  To connect this drive I've used an adapter 
which converts the SCA connection into a regular 68-pin internal one, then 
used a terminated cable with Ultra160/LVD/SE marked on both the connectors 
(there's 4 of them) AND the terminator.  I've tried turning the internal 
terminator in the Adaptec BIOS on and off with no change.  There's no 
other devices on this bus other than the drive & the host adapter.

Is this normal?  What do "User", "goal" and "curr" mean?  Why are there so 
many commands queued?
