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.

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.

To add on to this answer (which is correct):

Your "of" can also just be a regular file if that's easier to work with vs needing to create a new partition for the copy.

I'll also say you might want to use the block size parameter "bs=" on "dd" to speed things up, especially if you are using fast storage. Using "dd" with "bs=1G" will speed things up tremendously if you have at least >1GB of RAM.

I totally spaced on BS=4M which I believe is the standard block size for ext4
