I would appreciate advice from the community about a failing hard drive.
When booting up, the computer complained about /dev/sdb, which is a ext4
HDD with data (not the computer main disk). dmesg shows `AE_NOT_FOUND`
and `failed command: READ FPDMA QUEUED` messages (full dmesg log at
https://hastebin.com/raw/jebelileru).
It has finally booted after trying unsuccessfully to start /dev/sdb.
I launched smartctl which shows hard drive failure.

I did not try to mount the HDD. I plugged an external HDD (ext4) and
launched ddrescue. After two days it has recovered 33GB of 1TB but the
speed are now so slow it will take 7104 days to complete.
# ddrescue -n /dev/sdb

Should I wait hoping for a speeding? Should I pass different option to
ddrescue or use another tool?
