This will reveal if this drive supports SCT ERC. If it does, and it's
not enabled, it can be set to an obscenely high value, and then a
matching SCSI block device command timer might permit deep recovery by
the drive's firmware. And then you can just rsync the data from one
drive to another. I would not depend on SMB for this.

Was it you who told us of a script to cope with drives that don't
support SCT ERC?

OP: generally, if a drive can't read a sector in a few seconds, it
won't ever be able to read that sector. Possibly more data can be
recovered (with some holes) using GNU ddrescue, or the alternative
dd_rescue with dd_rhelp. Note that wither would be used to copy a
whole partition or disk.
If one has a backup, using rsync and getting the failed files from
the backup is probably faster than using either dd*rescue.
