It works just great with PC-Ditto, but I can't get it to work in native mode. The drive formats OK (using M. Braner's 40 track formatting program) and I can access the first tracks (including the root directory), but I get access errors on later tracks. I realize that this is probably because the drive's seek time is longer than the ST generally allows for, but I can't remember how to change the seek time. Just setting the location in protected memory doesn't seem to work. I know this has been posted before, but I didn't save the articles as I didn't need the info then. So, could someone please enlighten me about how to get this working? C source code or a pointer to a (cheap) utility would be great. Many thanks, Paul Gross gross@ihuxv.att.com or att!ihuxv!gross AT&T Bell Labs Naperville, IL 60566 (312) 979-1195
