[comp.sys.amiga.hardware] A2090A and Wren IV

zik@phoenix.pub.uu.oz.au (Micheal Saleeba) (05/28/91)

I've been trying without success to get a 300Mb Wren IV drive to work
with my A2090A controller. Is this the old Seagate problem coming back to 
haunt us? Am I doing something stupid with the cabling? Can the A2000
power supply handle the 2A at 5V and 2.3A at 12V that the drive sucks?
All I know is that the drive won't even select. Any ideas?

Thanks in advance,
			Zik

I can't imagine what the problem is... I have a WrenIV, and it worked just 
great when I borrowed a friends A2091. I simply plugged it in, and it 
worked. Have you had any success in getting the drive to work on other 
controlers? It yes, then I would be for taking your controler back ASAP. If 
no, then check the various jumper settings. Do you have another HD online? 
If yes, then make sure that both drives are not set to the same SCSI number. 
Does the Wren spin up (start spinning, go click, then do a bunch of seaks). 
If no, something is wrong. If, during the power up sequence, the LED flashes 
in a rythem (pattern), then there may be a physical error that the controler 
is detecting and barfing on.
      Hope this helps,
          Dan Bendiksen.
