Help To Recover Corrupted Files, After Recovery Software

[joko]

years ago i last used my 2TB MyBook WD hd drive, ive had 2 and found them both unreliable so they sit on a shelf unused
however, ive lost some old work and so im going back over all my drives, SD cards etc and searching them and also running recuva

on this drive, i've found loads of files and some have given me me back some of the lost files, however loads appear to be there, they have a page count, an MB size but when i open them, all there is, is pages and pages of this -
###################################################################################################################################################################################################################################################################

so this symbol replaces every letter in the doc

so does anyone know how i can turn them back into the proper files?

i think there are some files on the drive that are from a previous Recuva attemptt but i cant remember

also most of the pics are named, have an MB size and a file extension - jpg etc - but when they open it just says 'unsupported file format' etc

any ideas is any of this is salvageable?

im on win 10

thanks :)

I doubt it. All sounds corrupted.
You may get lucky if a good disk recovery programme manages to work out what the low level data should be and recovers it. But I'd not hold my breath were I you.

Possibly a long shot but I'll mention it anyway:

I've experienced 'unsupported file format' messages with jpeg images when the problem has been nothing more than an unrecognised file name. (e.g. the inclusion of a foreign character or a punctuation mark). Simply renaming those files (e.g. to test1.jpg, test2.jpg, etc) has fixed the problem for me on several occasions.

How did you create the backups in the first place? My Mybook came with backup software, which I ignored and used my own. It could be that if you used software that came with the disc to write the backups you have to use the same software to reinstate your files.
