On the subject of hard drive help, I have a Supra 20mb drive I bought several years ago for my A1000. The model is an Epson HMD726A. Epson says they have no information on the drive. Supra apparently threw out the information they had. The problem is that my A2091 does not recognize the drive. I tried RDPrep but I need the following information: Bytes Per Block Blocks Per Track Heads Cylinders Total Blocks Cylinder blocks. Nothing critical if I don't get this information, but I could use an additional 20mb if I could get it.

Since the hard drive's number ended in an A, I assume it is an IDE drive, doesn't the 2091 only work on SCSI drives. Did the A1000 use a Supra hard drive card to access the drive? If so, perhaps Supra could confirm if the drive is a SCSI of an IDE. Jim R. Ollick Using AP from Bergenfield, NJ

James, It's not IDE … IDE did not exist back then. -sja

Jim, IDE is a fairly new standard, so I'd suspect the Epson to be either MFM or RLL drives which many years ago one of the first Amiga harddrive controllers, ALF (= "Amiga Loads Faster"), well, controlled ;^) Back then the controller really had to do everything personally, like moving the head(s) to a certain track etc. while today this is usually done by the hard drive electronics themselves (IDE = "Intelligent Drive Electronics") I don't think any of today's controllers is able to cope with those any more… // Chris coming in from Germany \X/ on AutoPilot 1.071……….

You should be able to tell something from the data connector(s). If it's 1 50 pin header, you've got SCSI. 1 40-pin is IDE in the 3.5" size, the 2.5" IDE's used in the 1200 could have a 44-pin tiny metric connector. ST-506 drives use two connectors, a 20pin and a 34. -Jim MOS via Autopilot & Amiga

It is definately a SCSI. I bought two drives from Supra. I also have a Seagate which works find. I have the drives connected from the A2091 out with the Epson daisy chained from the Seagate. Thanks for your response. I hope I can get the information from someone.
