Update,
I'm trying to confirm my SA850 drives can access the 2nd head and am having lots of trouble.
Adaptec 1522CF on a DOS PC with imagedisk and 22disk and anadisk.
No trouble reading/writing 5.25, 3.5 drives.
I'm using the S2 option jumper, everything looks right.
I SHOULD be able to FORMAT B: /F:360 and succeed but DOS 5.0 and 3.31 spit out error m
essages when they get to the 2nd head. Not read.I've tried my own DIY 34-50 board, the DBIT and the texelec, with all the same results.I've tried as many jumper configs as I can think of.
I'm neck deep in this and need to get this resolved before I can confidently tackle the ibex ideas suggested.
