how to recover from damaged filesystem
by maxreason from LinuxQuestions.org on (#6QXVK)
While trying to copy a large directory from one HDD to another on Linux Mint v22 with drag and drop in the usual "nemo" application ... "something went wrong" and two other HDD not involved in the copy got screwed up.
I have no idea why two HDD that were not either source or destination drives (or OS drive) would be damaged during a copy. If you know, great, tell me. But my question is how to recover the data on those two HDD.
When the failure happened, the two HDD instantly became unmounted and the icons for those two HDD vanished from my desktop. Subsequently I was not able to mount those two HDD.
When I run the "disks" and "gparted" applications and display those two HDD, those applications say the filesystems are damaged. The "disks" application says "filesystem" damaged when I execute its "check filesystem" command on either of those HDD. But it does show the partitions on both HDD and the label for the partitions on those HDD are valid (unchanged from before the "crash").
One additional factoid. Both drives are NTFS, and that is shown by both "disks" and "gparted". So not everything is smashed to pieces on these HDD.
One more factoid. Both of these HDD are in an external HDD case that holds 5 HDD and plugs into a USB port on my Linux Mint v22 computer.
I don't have a windoze computer any more, so I can't plug the drives into a windoze machine to test them in windoze.
Any suggestions how to try to recover data? Truth is, I may have copies of the contents of these drives, but without being able to see any contents at all ... I can't determine whether I have backups or not. Dummy me ... as usual.
