Default Ext3 file recovery

If you mean recovering a deleted file, then no. The ext3 file system
does not allow for recovery of deleted files.

Yes, I meant file deletion.

If you unmounted the volumed quickly after the deletion, then Google
for ext3grep. It *may* recover your file. If you did *not* quickly
unmount the partition, then all is lost.

Q: How can I recover (undelete) deleted files from my ext3 partition?

Actually, you can't! This is what one of the developers, Andreas Dilger,
said about it:


In order to ensure that ext3 can safely resume an unlink after a crash,
it actually zeros out the block pointers in the inode, whereas
ext2 just marks these blocks as unused in the block bitmaps and marks
the inode as "deleted" and leaves the block pointers alone.


Your only hope is to "grep" for parts of your files that have been
deleted and hope for the best.

That's the official position, but read the following fascinating story
by somebody who had not deleted a single file, but rather his whole home
directory:
