Question:
I currently have a Seagate ST01 controller and ST296N 83 meg drive.
I would like to add another SCSI drive, probably a seagate STxxxN
drive. What will be required to make this addition?
Will the ST01 control several (2, or 2+) drives? What is required to
do this? What kind of cable will I need and where to find it.
Thanks Mucho!

I have talked to my dealer and another dealer who is specialized in hard drives. Apparently, you can add another SCSI drive as long as it is not bigger than 1024 cylinders. >Will the ST01 control several (2, or 2+) drives?

It may be a cheaper solution to just add an IDE adpator/drive depending on your application. Anyway, I would like to get a bigger drive which has >1024 cylinders and would like to get better performance out of the 85 Meg drive. Instead of going the IDE adpator/drive route, I decided to get a new controller (ALWAYS IN-2000) which is a 16 bit SCSI controller and can handle the bigger drive. However, it is CDN$200 more than getting an IDE controller with the IDE version of the same drive. -- Peter Yeung Amdahl Canada Ltd., Software Development Center 2000 Argentia Road, Plaza 2, Suite 300 Mississauga, Ont.

Your dealer is incorrect. The st-0x family of scsi controllers can handle up to seven (7) drives each. The limitation is with the driver (software) not the card (hardware). The MS-DOS driver supplied by seagate handles only two drives. Change the driver and you can get more (or less) supported drives depending on the driver you get. Furthermore, i am currently using an st-01 with a wrenIV which as >1400 cylinders and it does just fine. Nowhere in the manual does it mention such a cylinder limitation. Again, i think that this is probably a limitation of the software, not the hardware. >Actaully, you can add a different controller/drive combo (e.g. IDE, RLL or >even regular MFM) if you choose to.

I think it would be cheaper and more efficient to simply add up to six more drives on the single SCSI card that you already have. Then you can enjoy the parallel access that SCSI gives you. -- det@nightowl.mn.org
