Many hard disk applications will reveal the disk drive geometry for you: FWB Hard Disk ToolKit is very good (SilverLining is a bit wrong on the number of tracks… it includes spares). What you are really looking for are the total number of cylinders (‘nc’), the number of sectors per track (‘ns’) and the number of tracks (‘nt’). By far, the easiest (and cheapest) way is to use the SCSIProbe utility, by Herb Weiner (herbw✉wiskit.com), that runs under A/UX. This neat little package automatically generates disktab entries for your disks. Jim is maintaining a list of /etc/disktab entries. If you have any, send it to him and he’ll add them. The file is available on jagubox. lots of entries needed Just a note: the number of tracks (‘nt’) is equal to the number of heads.
