[comp.sys.ibm.ps2.hardware] Disk from model 30 wont be read in other machines

jumper@hobbes.ncsu.edu (Michael Lanham) (11/29/90)

I have some backup copies of my ALDUS PAGEMAKER 3.0 on 720 KB DS DD disks
formatted in my PS/2 model 30.  I used diskcopy to copy the originals
to the backups alos using the model 30 as the copy platform.

My problem is this: I tried to get my zenith 386sx to read the disks and
install the program and the install program refuses to recognize the 
PROGRAM/DICTIONARY disk.  DOS will get a dir from that disk, copy files, chkdsk
for bad sectors(none) but the PM INSTALL program wont read the disk.

WHY??????  I tried to use a friends model 50 (IBM PS/2) and his machine
would not read the second disk either.  All three machines read the INSTALL
disk but only my model 30 will read the other needed diskettes.

Help would be deeply appreciated

Wild Guess, here.  If the disk is a double-density disk, your low-density
3 1/2 formatted it low density.  The high density drive looks at the
physical mark (a hole thru the corner) of the diskette and says " Hey,
this is a high-density diskette!  I can't read it!".

Compare a low density floppy with a high density floppy and the physical
differences are obvious.  Maybe if you simply cover the hole on the
low density format diskette, the high-d drive will read it (?).
