The dd finished backing up after about 3 hours.
$ sudo dd if=/dev/sdc1 of=/mnt/image.dd bs=1M
==> 152625+1 records in
==> 152625+1 records out
==> 160039240704 bytes (160 GB) copied, 9750.86 s, 16.4 MB/s
Although I can't see to change the permissions of the result:
$ ls -l
==> -rwxrwxrwx. 1 root root 160039240704 Jun 1 12:13 image.dd
$ sudo chmod uog=r /mnt/image.dd
$ ls -l
==> -rwxrwxrwx. 1 root root 160039240704 Jun 1 12:13 image.dd
$ sudo chmod 555 ./image.dd
$ ls -l
==> -rwxrwxrwx. 1 root root 160039240704 Jun 1 12:13 image.dd
At this point, some people said to try to recover using
the backup; while others said I should work off the original disk.
I think I'll try the testdisk recover procedure first.
