Margaret: There are actually several reasons why different drive/controller combos will or won't work. Termination is a big factor, and with the GVP controller it seems like the 'regular' way of terminating drives (terminators only on either end of the SCSI chain) isn't always the way that works. Drive ID settings are also sometimes hard to figure out, as different manufacturers use different methods of setting the ID. Even within drive manufacturers, I've seen 3 different drives (all the same make & model number) that had different revisions of the firmware (ROM) on the drive, and all three acted differently. I had a Seagate ST157N hooked to both a Supra & GVP controller (both SeriesI & II) and never had a moments trouble (will it did suffer from sticktion, but I tried to never shut it off), my local dealer has had Fujitsu drives hooked up to GVP controllers (that's their controller of choice) with no problems, and I've had several Quantums hooked to GVP controllers that DID give trouble! Of the controllers that I've used (I currently use a 3000, so don't have much choice!) is 1. Microbotics HardFrame 2. GVP SeriesII 3. A2091 (my 2091 had older ROMs on it, I'm told with the latest ROMs it's much faster & more stable.) -Mike Schiller In sunny Fort Lauderdale
