So, you’ve ignored those S.M.A.R.T.
errors for a while now, haven’t you. Now you
realize that there might actually be something going wrong with your hard
drive. You try to naively copy data off, but it fails. But, no worries, there
is an option to
dd that can help you get most of the data off:
dd if=/dev/sdc of=/home/me/sdc.dd conv=noerror,sync
or, if using
dd if=/dev/vg0/failing-lvm of=/dev/vg0/new-lvm conv=noerror,sync
conv options specify that
dd should ignore read errors, and to
synchronize the read position with the write position when those errors occur.
sdd.dd or new
lvm volume could now be mounted:
mount -o loop -t ntfs /home/me/sdd.dd /mnt/old
Hopefully you can recover (most of) the files now.
