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. It may be a cheaper solution to just >add an IDE adpator/drive depending on your application. 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
