- Thanks for the info on the other extended disk formatter.
-
- I noticed that FDFORMAT uses a sector interleave > 1 on those extended formats
- which put more than the standard number of sectors per track. Presumably
- this is to compensate for the reduced inter-sector gap size. If the formatter
- you are using doesn't do that then it *MAY* explain the problems you have in
- using extended-format 5.25" diskettes.
-
- My system is one of those which does handle the extended formats:-
-
- 3.5" 82 cylinders 21 sectors per track
- 5.25" 82 cylinders 18 sectors per track
-
- I have never managed to get OS/2 2.0 to read low-density diskettes formatted
- to 80+ cylinders - OS/2 double-steps them erroneously. Previous corres-
- pondents have commented on this; OS/2 seems to go part way towards using
- the disk tables but only part way.
