I assume that you still have only Linux installed, and that the
problem partition was not touched since Findpart was run.

I also assume that you know how to mount a partition read only in
Linux.

You then can download the files fp1-1a.bin and tsang1.bat in

http://inet.uni2.dk/~svolaf/tsang1.zip

Put tsang1.bat and fp1-1a.bin on the boot floppy.

Normally a wrong FAT32 boot sector can be edited, but in this case the
boot sector contains a mix of FAT16 and FAT32 values. Therefore a new
boot sector is in fp1-1a.bin.

Run tsang1.bat, which contains:

if not exist fp1-1a.bin goto noexe
findpart getsect 1 330 1 1 1 fp1-1b.bin noheader
set findpart=edit
findpart findfat 1 330 1 33 3601 fat2to1 788
findpart putsect 1 330 1 1 fp1-1a.bin 788 00000000 checkfile
fp1-1b.bin
findpart 1 330 1 - 0B 330 1 1 787 127 63 330 788 128 63 26
set findpart=
findpart 1 fp1-1.txt
:noexe

(Not word wrapped in the batch file).

After that, you can attempt to mount the partition read only in Linux.

Insert the content from fp1-1.txt here.


Svend,

You are brilliant!

I ran tsang1.bat from the boot floppy and it produced the output in
fp1-1.txt as follows:

I booted linux and mounted the filesystem and could see the files!

Fantastic!

Is there more to do?

I can't express how much I appreciate your help.

Thankyou once again.
