A primary partition on C drive of one of my computers is gone. FDISK says
that there is no partition on that drive.
Is there any way to undo this without losing the information on that drive?
I will of course need to do this from DOS...

I believe old versions of the Norton utilities disk diagnostic program
(NDD.exe I think), can search a disk and look for a valid dos partition
if the partition table is bad.
I'm sure you should be able to find a copy on the net somewhere.....

and write them to the unused sectors on C0 H0.
However, note that if you were using a dynamic drive overlay to

the DDO sets up a dummy partition for itself to boot from, then hides
that partition when the DDO software is loaded.

I just did this - but I had to pay for it. NTFS Mechanic worked for me. Somehow I lost
the entire directory structure on a crash. It was replaced with a single directory like
qoieqoewfnjs with nothing in it.
It took about 20 hours to recover a 250G drive but it did do it...

Depending on your resources, there is a version of Norton Ghost which
will back up the partition. I say depending, in that I don't know what
media you might be able to copy it to. If you have a system with IDE,
you can use another IDE drive, as ghost will create an image file on a
formatted fat32 file system. Ideally you could write it to a USB drive,
but it may be too old.
The UBCD if you can find it has a great set of utilities for recovery of
corrupted partitions such as you mention. You would take the ghosted
image and restore it to a utility drive on a new system The recovery
could take place on that ghost restored image, and not risk any damage
to your original.
I have done this not only with this method, but have taken the ghost
restore to a vmware utility system for recovery in one instance.
The trick is finding the floppy version of ghost, if that is the only
media you have. If you can boot a cdrom (sound like that is unlikely)
you could directly use UBCD (Ultimate Boot disk for Windows).
the UBCD I have seems to have most of Windows XP implemented in the PE
environment which is booted from the CD.

You don't really need DOS, have a look at

and

I've just used TestDisk to recover files from a broken FAT on my cell

I see that it can run under DOS, though I used ubuntu.

I had to fix lost partition tables several times (friends do strange
things), always used `gpart' (running on Linux, most of the Live CDs
have it) in recent times.
