ext234 do have an option to scan for bad sectors and create a bad
sector map which then can be used at mkfs time, and ext234 will avoid
using those sectors. And also the md driver has a bad sector option
for the same, and does remapping. But XFS and Btrfs don't do that.
If the drive is under warranty, get it swapped out, this is definitely
a warranty covered problem.
Thank you very much.
Once upon a time...(I am old), there were lists of bad sectors, and the
software did avoid wrting in them. It seems to have disappeared. For
which reason ? Maybe because these errors occur so rarely, that it is
not worth the trouble ?
