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.

What would be the best way for me to recover data from my old laptop's hard drive, which seems to have a bad superblock? (lemmy.ml)

I got an external hard drive enclosure for the purpose of recovering some of the files from my old laptops hard drive. The hard drive and all of it's partitions show up in both disks and gparted but it wont mount. When I tried to mount it manually, it gave the error message stating that it can't read the superblock. I've never had to deal with this issue before, so the only things I've tried so far were fsck and the data recovery option in GParted, and neither of them helped.

I tried searching about it online but all of the solutions I found online either didn't work or required methods that are currently not possible for me. The hard drive had Ubuntu (22.04 if I remember correctly) installed on it and I just need access to the files in the sdd3 partition, which was formatted in ext4.

If the disc is corrupted it may be failing, recommending ddrescue over dd is probably a better call not knowing anything else about this situation. Essentially, no reason not to use it.

I swear by ddrescue. It's a situation I strive to never be but i've been there before. I used it once to rescue an employees masters capstone project from their dead work laptop.

After reading about it - true. Disadvantage of doing this stuff for a long time - you miss new developments. Only reason I'm aware of testdisk is that I lost the sources of my own superblock search tool, my old binaries broke with a newer glibc, and before reimplementing it I checked if sombody else had done that in a more usable form in the meantime.
