Did I forget to specify block-size (or the like) to dd, or is that my data is plain wiped ? > Or is there still other things to try? First rule of data recovery - do not modify your disk further... I can't say offhand, but creating another partition and doing mke2fs on it is not a great idea, because it is entirely possible that this overwrote some of the data that you wanted back. Whenever you are doing partition manipulation you are also well advised to save the output of "sfdisk -l" or equivalent (i.e. start/end sectors for each partition) so you have something to fall back on. As for recovering email, what I would do is "strings /dev/hda7" or similar, and dump the output to ANOTHER disk/system (via ssh or NFS or something that doesn't affect the disk in trouble). You can likely get a bunch of your data back (probably easy to find relevant data using grep or something on the output text), but since it is email folders it is likely that your files were very fragmented on disk, so you may have a bunch of work to edit it into a useable form. How much work you do depends on how important your data is.
