PhotoRec UI improvements

#1 Post by markmarques »

I had using photorec | Testdisk for the past 10 years , always with success ...
( Both Linux and Windows versions )

But recently I have found a bit of a small issue:

(I am trying to recover the files from a DVD | MDS set of files ) .. but beforehand "recovered" the full ISO ( full single continuous single file Track01.ISO with 4.3Gb ) with Isobuster TM . )
In Isobuster It listed and were "possible" to recover several files ( MP3, MPG , ...

So my idea was why no try to use Photorec ?
Got the latest windows 7.2 WIP windows binaries and pointed them to analyse Track01.ISO file ...

And here are my small comment:

If I select only MP3 and MPG type files It find some of them within a minute or two and exits with sucess...

But if I select to recover all the known types of files it starts and after 3 hours it had no feedback whatsoever ...
( the process were alive and responded to the "STOP" button correctly though, in the next iteration call indicated if I would like to continue where it was last time ... but still no feedback ...


My comment and idea would be if possible to have some kind of visual feedback in the UI ...
something that could give a rough idea if the program is doing anything like the "old" "/|\" indication or similar in the interface ...

Another comment to improve would be the filetype selection , would it be to much to ask for multiple columns ... ( something similar to the Filesystem type menu choice ... )




Thank you in advance
Mark Marques

Isobuster understands ISO and UDF and will probably try to access files using metadata instead of fingerprinting. This would require at least a partly working file system.

If your DVD used the ISO or UDF file system you can see here
https://www.cgsecurity.org/
that it is not listed.
Testdisk does not support it.
Use commercial third party tools instead.

The most urgent issue not yet done with file type selection is an entry in the manual translating file type into the associated family that has to be selected.

Christophe Grenier will certainly think about your proposals once he reads your posting!

There may be an endless loop.
Can you share privately this iso (ie. google drive) so I can try to reproduce the bug ?

Sorry for the delayed answer...
I am unable to send the file as I have bandwidth restritions ( the ISO file is almost 5Gb ) ...

Nonetheless how can I check if it is a "loop" detail ?
Is there any "debug | log mode" to activate ?
