One doesn´t and one does:
# smartctl -l scterc /dev/sdd
smartctl 7.2 2021-01-17 r5171 [x86_64-linux-5.11.10-200.fc33.x86_64]
(local build)

SCT Error Recovery Control command not supported
# smartctl -l scterc /dev/sde
smartctl 7.2 2021-01-17 r5171 [x86_64-linux-5.11.10-200.fc33.x86_64]
(local build)

SCT Error Recovery Control:
Read: 85 (8.5 seconds)
Write: 85 (8.5 seconds)
So I guess the /dev/sde drive is set correctly, right? Or would you
recommend disabling SCT ERC for this drive?
