 PostPost subject: How do I save an XDF floppy image..?        Posted: Sat Mar 08, 2008 3:49 pm

I'm currently rounding up all my dos collection from the various backed
up CD's from over the years, & also the IBM versions...
Which also includes all the genuine versions on genuine disks...
Iv'e run into a small problem with the sets of IBM PC-Dos I have,
whereas all disks after disk 1 is in XDF format...
In doing a search I found that the 1st disk has a proggy on it called
XDFCOPY, but from what I can make of it after running it from a
dos prompt, it only seems to give options of disk copying...
Now iv'e seen others here hosting version 7 & 2000 before so
I guess there's a way to image them, just not in winimage...

Any pointers would be appreciated, these disks are japanese too
so I guess there's likely to be someone here who wants them...

Thanks..!

I wanted to save the IBM OS/2 Warp 3 (Red box) they were also in XDF format.
So i also tried a search but then the one about a command prompt cought my attention, i tryed it but not luck.

The best solution is making images from a computer then can read XDF (from OS/2 Warp) it must be installed on a real computer, even virtual IBM OS/2 Warp cant read them.

XDF was just a terrible way to get more data onto a practically identical 1.44/2M floppy disk. The real problem ends up being that the sector sizes vary throughout the whole disk (physical sector sizes, not logical). This means that you HAVE to have, not only special software to deal with it, but a drive that can read them.

At least with the 2.88/4M disks, the physical sectors were all 1024 bytes, so a disk image is easy to deal with.

Use xdfcopy on a physical PC-DOS / OS/2 box. Recent versions can accept drive letters and image file names as both source and destination.

You can also use a floppy drive emulator. I use it quite often when dealing with old floppies or odd floppy image sizes.

http://chitchat.at.infoseek.co.jp/vmware/vfd.html#top

It installs as a device driver, you can configure it to use RAM or a floppy image file. And you can configure any "standard" floppy size and format. Windows even detects it as a valid floppy drive. And it's easy to enable and disable.
