The 80pin 146GB U320 Drive and adapter I bought earlier don't seem to work drive powers up but is invisible no matter where I put it either internally or externally. the external enclosure I have has active termination on it. when I tried internally I used a pass-through terminator no matter the jumper settings TPWR on off or ID setting drive is not seen on the bus. If the drive is not terminated the drive light stays on but when terminated looks and sounds like its running right. SO I am guessing this drive doesn't have backward compatibly. So a friend was getting rid of his scsi stuff. All of it 68pin, he gave me a 68pin 4.5GB HDD, 4 device 68pin cable and a 50 female to 68 pin female adapter(he was using it to use a older 50 pin controller with 68 pin drives). I was asking if this adapter would work in the Q700 before I opened it up because its a pain to get the PSU out.
