this, e.g. marking this sector as unusable?
Thank you,

$ sudo dd if=/dev/zero of=/dev/sdb1 bs=4096 count=1 oflag=sync,direct
dd: error writing ‘/dev/sdb1’: Remote I/O error
1+0 records in
0+0 records out
0 bytes (0 B) copied, 0.00142455 s, 0.0 kB/s
There should also have been some system error messages logged which
might be informative.
When any reasonably modern (last 20 years, or so) drive shows an
I/O error on a write operation, it generally means that the drive
has run out of spare sectors or has some problem other than media
errors. Such a drive is long past the time it should have been
replaced.
It would be interesting to see the output from
"smartctl -A /dev/sdb", if the interface supports it. (Not all
USB <=> SATA bridge chips support the necessary commands.)
