[comp.binaries.ibm.pc.d] 1800k disks?

ccs029@dino.ucdavis.edu (Val Luck) (03/31/91)

Hello:

A friend told me about a neat little utility that would let you put
1800k of data on a 1.2meg 5.25" floppy....  has anyone heard of this
program and is it realiable?

Thanks!

There is a program called FDFORMAT (I think) that gets extra space out of
floppies. Let me know if you can't find it. There is also a program called
800k that lets you get 800k out of a 360k floppy in a HD drive. Both of
these programs need to have a TSR running because the BIOS has a bug that
resets some disk parameters, but they work fairly well.

try anon ftp to SIMTEL: PD:<MSDOS.DSKUTL> FDFORM16.ZIP
btw -- this is a VERY DANGEROUS thing to do if you intend to use
the disks for archiving any valuable info.

I only know there is a program which let you make the disk larger.
for 1.44M disks, it will go up to 1600k, and 1400 or something like that
for 1.2M disks.  This program has a little compatibility problem.  I used
to have a PC compatible 286, and it works fine.  But now I got a PS/2,
which is also an 286.  Since this one is IBM, I guess the bios is
different, and I had to run a TSR program in order to read the files.  The
program is called Maxi.

Hi!

The program FDFORM16.ZIP available will let you get 800k from a 360k
floppy, 1400 from a 1.2 and 1600 from a 1.44.  I used the program to
store .ZIP-files on 360k's formatted to 720k.  This worked OK on my
machine, but a friends Commodore PC-40 wouldn't touch them, even with the
supplied TSR installed. Most other computers seemed to agree to the
format after some coersion.  I stopped using it after I found out that
disks stored for some time developed soft errors, "fixable" by a retry
on read.

Regards,
