If it failed during write, your e2fsck is just removing the bad sectors not magically repairing what ought to be there. You can only repair a filesystem if you can read failing data and replace it with undamaged data. And it sounds like the failures are in important places if that's happening. You could have a cascading failure (not just static errors, but increasing ones). Some cards can self-repair, so you mightn't notice problems until the failures become severe, and external repair attempts could fight with internal ones. A failing card is unreliable, it's not worth the grief. -- uname -rsvp Linux 3.10.0-1160.119.1.el7.x86_64 #1 SMP Tue Jun 4 14:43:51 UTC 2024 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
