[SOLVED] Failed partition resize: can I recover my data?
During the process of resizing a partition with gparted, I got an error:
check filesystem on /dev/sdb2 for errors and (if possible) fix them 00:00 ( ERROR ) e2fsck -f -y -v /dev/sdb2 /dev/sdb2 is mounted. e2fsck 1.40.2 (12-Jul-2007) e2fsck: Cannot continue, aborting.
The problem was that Ubuntu or Gnome had automatically mounted the partition sdb2, which is on a hard disk which is hooked up through usb. I now have one small partition and a lot of unallocated space on the drive. I meant to have one big partition with the data from the small partition on it, but it seems gone now! The device can be mounted but appears to be empty. However, gparted says 79% of the partition is in use.
Can I recover the data?
Maybe I should run the command e2fsck -f -y -v /dev/sdb2 again but without the partition mounted?
I have a partial backup, but all my storage space is now taken.
Here's the entire gparted_details.htm:

Why should I run testdisk from a live CD and not from my normal Ubuntu installation?OS's I use: Debian testing, Debian stable, Ubuntu, OpenSuse 12.1, Windows 7, Windows Vista, Windows XP
I don't think testdisk is installed by default and running from live CD should work for all drives in the system - no issues with things being mounted etc. It also minimizes the chance of data loss due to running the system.
That makes sense, thanks.OS's I use: Debian testing, Debian stable, Ubuntu, OpenSuse 12.1, Windows 7, Windows Vista, Windows XP
I got my data back using testdisk running from the PartedMagic live CD.
Thanks Capser and Jonathan!
Glad to help you Daan !!
