    Glad you got your stuff back. Also tells me photorec works a lot better than extundelete.

  • the real advantage of extundelete was it recovered the names and directories aswell, but the result was maybe 10 % of the lost data.


    With Photorec it's perfect. The only thing i do not understand, my *.mp3 files are still having their tags, so with mp3 tag i can recover the name.


    My movie and also *.jpg files have also been "tagged" but lost their tags during recovery.


    I gotta find out why, cause if i would be able to give them a tag that can be recovered Photorec would be my bread and butter in file recovery :)

  • Good to hear, most of your stuff is back!


    I'll test photorec and extundelete in a VM also and report back. Additionally there is "ext4magic".
    Let's see, which is the best one

    Yep. Including names and directories! I think it´s just a matter of HOW you deleted something. A fried of mine deleted his whole raid via CLI and rm -R. I recovered -everything- with extundelete without any data loss.


    Very excited about your feedback Solo!

  • going to test ext4magic and will report back.


    I guess with SnapraidFix it has overwritten a lot. Maybe with out this command it would have worked with extundelete aswell.

    I gave it a try today with:


    ext4magic /dev/sde1 -M -d /mnt/backup/recover/disk1


    The only thing happend was :


    Code
    root@sysresccd / % ext4magic /dev/sde1 -M -d /mnt/backup/recover/disk1
    Warning: Activate magic-scan or disaster-recovery function, may be some command line options ignored


    Since them nothing is happening...i took the paramters i found on: http://ext4magic.sourceforge.n…en.html#Recovery_examples



    Forget about it.....it took about 90 minutes and now started...let's see what is happening
