Title: floppy IMG file backup.
Post by: zcoder on September 24, 2008, 04:18:49 AM

Here is a program I made by mistake, and I thought I would share the code.
The mistake I made was having my filename and path, messed up.(mangled)

This did not open a file on a floppy, But what it did do was open the
floppy drive as a device, allowing me to read and write to each sector
on the drive. So I stopped writing the program I was working on and
played with this and found out I could read floppy images to disk files
and back to floppies. this was good for making boot images. it also worked
on Cd's to make CD IMG files.

So I thought some of you might be interested in a program that could
make floppy IMG files and restore them onto other floppies. The source
is included.

I also would like to know from others to test this out if it works, and if it don'y
could you let me know your OS? I have XP Home, and I am not sure if this
works accros other OS's

You don't need to have the hardware to do it, you can use emulation, for example VMWARE Workstation can mount disk images in its virtual floppy drive :wink

Nice clean source, shame you're using another assembler :P seems everyone on masm32 using everything but masm ;) code seems to work fine with vista home.

You can access any drive by opening "\\.\X:" (where X is the drive letter) with CreateFile and then treat it as a normal file - just remember to open with "FILE_SHARE_READ or FILE_SHARE_WRITE"
Works for all version since windows 95 (though I think there were some limits on 95/98)

See also: "\\.\PHYSICALDRIVE0" for the first hard-disk (starting from the MBR, rather than the first partition.)

I sure would be careful, though! :U
