I would like write some data recovery software

[gel]

I would like to write some data recovery software as a learning thing.
The sort of thing that you would use to recover data from a currupt HDD
or floppy etc. I would like to be pointed in the right direction as
far as modules to use and suggested approaches.

Uh... this is highly OS dependent... You need to be able to do
direct RAW disk sector addressing; something that OSs don't really like
to give to applications. You also need very good documentation of the
file system (and the only file system I know well enough to navigate at
that level is one I haven't used in over a decade -- the file system
used by the Amiga, which was a hashed-head, multiple linked list
scheme).

Yes, OK I guess NTFS would be of most interest to me. From the
research I have been doing it may be that it is a fairly in depth
undertaking and possibly not such a good project considering my
knowledge of NTFS and python. I will have bit more of a look about.

Thanks

what kind of recovery? disk broken into pieces and recover from it?

Then you'll have a hard time because NTFS specs are not available for
free. Just reverse engineered stuff.

Once you get a way to access the bytes to recover... the Hachoir library
can be interresting as a model to map structures on these data.

To recover data from a corrupted HDD or floppy manually, you can start by using built-in tools like Windows’ CHKDSK to fix disk errors. You can also try accessing the drive using command-line tools to retrieve specific files or attempt booting from a Linux live CD to copy data from the corrupted drive.

However, for a more efficient approach, the BLR Data Recovery Tool is a powerful solution. It simplifies the process by scanning the corrupted drive, offering selective recovery options, and restoring lost or deleted files while maintaining the original data integrity.
