Help! Undelete ext4 files with Foremost?

[ubu-for]

Does anybody know if I can undelete files from an ext4 partition with Foremost?

Damn fast and unstable ext4!!!

Maybe I have the same problem like the following user?

The application would need to be patched to support EXT4 properly, and considering that the latest upstream release was in October 2008, I think you can guess the answer to your question.

I read that a new version of testdisk (6.11) that supports ext4 is available. Doesn't appear to be in the Jaunty repos yet.

Why enabling ext4 ? Canonical won't enabled it until Karmic... So, if you lose data without doing backup, this is your fault, not ext4 one.

Someones gotta test it.:). In the mean time, it does give a notable performance boost on file system operations. Apart from possible bugs it looks like a number of utilities don't support it yet.

I haven't lost my whole partition. You can't backup every new folder!

Sure it's ext4's fault! Ask Linus! ;)

I've downloaded a rpm of Testdisk and converted it to a deb file with Alien, but now which option allows me to undelete some folders and files?

[ubu-for]

Photorec, a part of Testdisk, is very easy to use, but quits always with the following error message after I've selected the folder where to store the recovered files.

Filesystem analysis, please wait...
*** glibc detected *** corrupted double-linked list: 0x0819faac ***
Aborted


Any ideas?

You could try sending a problem report to the dev:

If I google the error message, I think it's because I took the rpm which wasn't compiled for Ubuntu.

I just had a go at downloading the source from cgsecurity. I managed to successfully compile it and it seems to work.

Instructions (http://www.cgsecurity.org/wiki/TestDisk_Compilation)

I had all the libs except uuid-dev zlib1g-dev which I installed via apt-get.

There seems to be a line missing from the compile of testdisk itself. They have:

./configure
make


I also did a

sudo make install

Thank you very much alphacrucis2 for your great support!!!

I thought the Linux version of Testdisk have to be compiled but I only had to extract the tar.bz2 file and started Photorec with the following command.

***@***:/$ sudo /home/***/testdisk-6.11/linux/photorec_static

This Linux version of TestDisk & PhotoRec should work on any 2.6 i386
or x86_64 kernel. It's a static version, the binary doesn't depend on
shared libraries.

Finally Photorec could recover most of my files and all the rest I'll get back soon or will be a warning from ext4 "Never move files! Copy only!".

P.S. Photorec found really old files, too. Here's one of them. :mrgreen:
