- I tried it last night and indeed InfoPlus (1.55) can, without any
- diskettes in the drives and without any visible (access light) access to
- the diskette drives, determine the following "BIOS disk parameters:"
- (Page 14) for my A/B drives: 1.2MB 5 1/4" / 1.44MB 3 1/2", 2/2 Heads,
- 80/80 Cylinders, 15/18 Sectors/track and 512/512 Bytes/sector.
-
- So if InfoPlus can determine these physical specifications of the
- drive, then so could the MKS dd(1). With these physical specifications
- of the *drive*, it can try to determine the same physical specifications
- of the *diskette in the drive* (of course "Sides" instead of "Heads").
-
- As far as I know the source of InfoPlus is freely availble, probably
- on SIMTEL (I got my binary and old source from comp.binaries.ibm.pc), so
- if you want you can have a look at it.
-
- I think that the information screen (whatever it is called) of
- Norton's NU /M (maintenance mode) can also determine the physical
- specifications of (some, i.e. the ones which are hardware compatible)
- non-MS-DOS diskettes, at least for the 360KB/5.25" case I reported
- earlier (I haven't tried it with 180KB/5.25", 720KB/3.5", 360KB/3.5"
- (single-sided, MSX-DOS), etc..).
