Has anyone successfully added a Seagate ST251 40 Meg. Hard Disk to a AT&T 6300 PLUS? The PLUS normally uses a CDC WREN II 40 Meg. drive but the Seagate is substantially less expensive. Any assistance would be greatly appreciated. Thanks, Tom

It can't be done without a motherboard BIOS change if you use Simul-Task. There are eight drives that will work with the PLUS but the ST-251 is not one of them. >The PLUS normally uses a CDC WREN II 40 Meg. drive but the Seagate is >substantially less expensive. There are two good full height alternatives, the Seagate ST-4051 (40Mb/34ms) or the Miniscribe 6085 (72Mb/28ms). I can mail the list of "OK" drives to anyone interested (I posted it a while back) as well as a recommended outboard enclosure for the hard disk(s). You might be able to use a drive other than the "magic eight" if you use the BIOS on the disk controller and I suspect that you can if you only use MS-DOS. If you want to use Simul-Task you *must* use the motherboard BIOS even though your controller could handle the other drive. Don't fall victim to the nifty prices or claims to the contrary, the parameters for the drives are hard coded into the BIOS. Presumably the EPROM's could be changed, does anyone know where the drive table is? Bill Kennedy {cbosgd | ihnp4!petro | sun!texsun!rrm}!ssbn!bill

If you can do a low level format and specifiy non-standard parameters, all you really need to know are number of heads and cylinders of the respective drive. The ST251 has 6 heads and 820 cylinders. Precomp and Reduced write cylinder are "none". I remember trying to format an ST251 in a Sperry and had similar problems until I used a hard disk utility called "Disk Manager" from Ontrack Systems.
