[ To Greg ]

The problem still remains with Linux v5.12-rc1 (see [1]).

Yesterday, I ran some disk-health checks with smartctl and gsmartcontrol.
All good.

For the first time I used badblocks from e2fsprogs Debian package:

root# LC_ALL=C badblocks -v -p 1 -s /dev/sdc -o
badblocks-v-p-1-s_dev-sdc_$(uname -r).txt
Checking blocks 0 to 976762583
Checking for bad blocks (read-only test): done
Pass completed, 0 bad blocks found. (0/0/0 errors)

Good, there is no file-system corruption or badblocks or even a hardware damage.

Anyway, feedback is much appreciated.

Thanks.
