Broke a partition. Is there any way of saving it? (lemm.ee)

While I was switching distros, I accidentally broke a partition. I'm almost certain that all the data is there, but it doesn't have a filesystem (I used ext4). Is there anything I can do to fix it, similar to changing the file extension without changing the contents. PS: It's a data partition. I was trying to resize it, accidentally also moved it to the left, found out that it was taking forever to move it, so I cancelled it. Finished the move to the left operation (I think), but it threw up an error about the filesystem. I don't remember what it was, though.

Thanks to everyone who suggested Testdisk. It worked almost perfectly.

You can try fdisk.

If the partition table is there - create a new partition at the exact same location, of the exact same size.

If the partition table is not there - create *the exact same type (mbr vs gpt) partition table, then do the first if.

Fdisk should tell you that it found a filesystem signature. Do not wipe it.

... exact same starting block, size and geometry.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
