I just removed a bunch of Personal stuff I should not have. Is there anyway to undelete???
Jerry
What I do is mount the ext3 in ext2 mode and use mc to undelete all the files in another disk

But ext3 deletes/blanks all the directory info - eg the complete filename when a file is deleted, so you cant know which inode the file lives on ...
Sohow would mc undelete them ???

There are also 3rd party file recovery utilities (usually not free). If the blocks do not get overwritten then it may be possible to recover the file. I used a product call Stellar Phoenix before which indicates that it works on linux file systems.

The only way that it could (on ext3) would be to do a brute force search, and then reconstructing large or binary files would be near impossible.
The information just is not there to work from .

I've used the tools mentioned here
http://www.fish2.com/tct/help-recovering-file
in the past. Painful, but it works.

Lazarus just analyzes blocks in a sequential way, looking for stuf that file(1) or some heuristics for text files can identify. It will not handle fragmented files. So, it will only help with files smaller than the block size and files without fragmented data blocks. Though, this may help:

That's very tedious to do. You could find all unreferenced blocks with some work. But the only thing that you will get from that is just a dump of blocks. And it is nearly impossible to make something out of that, considering that there will always be block fragmentation in variable data.

BTW. I just looked up their site, and it says "Provides recovery of *deleted file(s)* for *Ext2* File system only." (emphasis added)
The disk I have indicates EXT3 as a supported file system but I have the Recovery suite. However I would not be surprised if it did not work as they said.

The impression that I get is that they support file undeletes on ext2, and other features on ext2/3. So, the program may support ext3, but not for undeleting files.

Jumping in late here, I recalled this snippet from NTK a few months back...
>> TRACKING << sufficiently advanced technology : the gathering
If you want to be truly loved, write a data recovery utility. We can't imagine there's a day when Christophe Grenier isn't swathed by offers of beers, steak dinners and marriage for TESTDISK and PHOTOREC, his two open source disk and file recovery utilities. The test TestDisk gives is sort of a final exam for your futzed partition block, quizzing your unreadable drive for tell-tale NTFS, HFS+, Ext3 or what-have-you data, and cribbing the lost partition data from what it finds. PHOTOREC gives up on such fripperies as a filing system and instead grubs directly on the drive for file data, spotting beginnings for popular file formats and having a stab at where their ends might be hanging. PHOTOREC, as the name suggests, started as a utility for clawing back pictures from bit-rotten flash cards, but can now sniff out files from Ogg Vorbis to Microsoft Powerpoint. Both utilities will run on Mac, DOs, Windows, Linux, and probably vegetable oil for that matter. Forget about them for now - when you need them, you'll find them. http://www.cgsecurity.org/wiki/TestDisk_Download - though you'll waste an hour searching NTK for "olive oil" http://www.flickr.com/photos/manuelidades/113461346/ - voila! c'est un web deux point zero shot de screen
Photorec might help if you know what you're after. It's often worth unmount a filesystem you've deleted stuff from and, if you have the space, just dd-ing the whole partition to another filesystem somewhere for later analysis. There's a good (if somewhat old) article on this from Sys Admin Mag:
