[ale] gddrescue

[dev null zero two]

yes. store image file and log file on known good disk. try with -n first to
grab as much good data as possible first in the case of the drive getting
worse over time. afterwards try without -n and then play with other
parameters. use a logical data recovery tool on the resulting image if
there was moderate physical damage and the image file is incomplete.
