adfs deleted files?

[gtoal]

I have a disk image file https://gtoal.com/acorn/arm/notblank/BLANK.ADF which none of the utilities I have for reading Acorn disks show as having any files on it. But 'strings' of the image suggests there is quite a lot there. My guess is that I saved the image to be used as a blank after deleting all the files on the original floppy but not having reformatted it. I'm wondering if anyone here has any utilities for undeleting ADFS files? Either something I can compile and run on linux, or something that runs on a Beeb or Archie that you wouldn't mind using on that image file for me? (I don't have a working Beeb or Archie at the moment myself).

It's possible that I do have already the significant files on that image but it would be nice to know for sure.
(The other files I have which look similar are in https://gtoal.com/acorn/arm/DISK0406/ and https://gtoal.com/acorn/arm/DISK0407/ )

Thanks,

G

The ADF2INF.py tool in this repository lists the disk contents as this:

Code: Select all

$.aof (empty)
$.Decode        8000            BCBC            F040

$.tmp (empty)
$.Twin          8000            8000            7C68

Mounting the disk in RPCEmu also shows that it has these files.

Thanks. I'll get a copy of that utility. It looks like there's nothing significantly new there. The "doit" files are just 1-liners to compile and link one of the programs. Everything else we have already. Appreciate you checking it out for me.

Just for interest, recently I had to manually reconstruct the map & root of an ADFS disc where track 0 had become unreadable:

If you've got a valid directory tree, you can recreate a free space map with MkMap: link. I keep meaning to write the complementary tool to recover the directory tree.
