[comp.binaries.ibm.pc.d] larger density disks

sks@mentor.cc.purdue.edu (Dan Schikore) (02/04/90)

I recently downloaded fdform15.arc from simtel20's <msdos.dskutl> directory.
I've been able to format my 360Kb disks to 410Kb using this utility.  I
would like to hear about experiences anyone else has had with using this
program regarding how reliable data retrieval has been, etc.  Thanks,

I regularly use this program to format DS/DD disks to 800k and DS/HD
disks to 1.48Mb, and I have NEVER had any problems at all. It's a
great program.

	Can you make the disks bootable?  I have a program called MAXI V1.51
which formats 360K to 420K and have never had a problem with it.  The
registered version allows you to make the disks bootable.

You can in principle use the DOS SYS command. However, most machines
require you to have the memory resident program FDREAD.EXE installed
before they will read the HD disks formatted with 18 sectors per
track, so if this is the case you won't be able to boot from this
disk.

In the case you mention, there should be no problem, as I don't
think the difference in formats would require the TSR, so you should
be able to boot from the disk OK.

After reading the documentation that came with 800kb.arc (available on
SIMTEL), I was led to believe that some BIOS had bug which prevented
one from using 800kb disks without the TSR program.

So I tried 800fmt without using the supplied TSR program, and got a clean
format, and DOS was able to read and write to the new format without
difficulties. So I believe my BIOS (AWARD) does not have the bug.

I was wondering if anyone who has 96 tpi drive could tell us if they
also had to use TSR or not, and also to indicate their BIOS, and version,
if possible.

Thanks !!!

Paul.

Well, I started using 800kfmat with Phoenix BIOS 1.10, and I could read the
disks it formatted with no problems.  Norton Utilities still had some 
problems, but I still managed to look at clusters, etc.

Then I got an update to my BIOS to 1.10 10A, and now I can't read my disks
without the TSR.  Norton Utilities also barfs, and asks what kind of disk
it is (from the standard 360K 720K 1.2MB choices).

I always thought updates were for taking OUT bugs... :-)

My machine is an Epson Equity II+, which definitely insists on the
FDREAD TSR being installed. If not, I can list the directory OK, but
if I try to read or write a file, after a few sectors I get a
"sector not found" message. By the way, this is with disks formatted
to 82 tracks, 18 sectors per track.

As far as I know, the BIOS is Epson specific, though this may be
wrong
