We have recently replaced some Hitachi 71 Mbyte disk drives (Model DK511-8) with larger drives. (These are on a Silicon Graphics workstation). As a result, a 71 Mbyte drive is available for use on my IBM-PC/AT, which spends most of its time running Xenix. The drives have the configuration: 32 sectors/track, 823 cyl, 10 heads. They use a ST506/412 interface. I use the DUB14 ROM upgrade in my machine to recognize lots of different kinds of hard drives, but It appears that most (all) drives for the standard IBM-PC/AT have 17 sectors/track. Can I use these drives with my standard IBM-PC/AT (real IBM) hard disk controller? If not, is there a controller that I can use for these drives (I would rather spend $200 for a controller than $900 for a new drive). I note that the current version of Xenix can be configured for non-standard disks, but does the controller understand 32 sectors/track (and what if I need to do a hard format)?
