1 Hello,
2
3 I am trying to recover data from a failed drive. An initial attempt with dd
4 took over 12 hours and it was not even at half of the 80GB damaged drive; so
5 I quit. Info on the web pointed me to ddrescue
6
7 ddrescue -n /dev/sda /dev/sdc rescued.log
8
9 which has taken over 6 hours so far
10
11 Press Ctrl-C to interrupt
12 Initial status (read from logfile)
13 rescued: 0 B, errsize: 0 B, errors: 0
14 Current status
15 rescued: 58656 MB, errsize: 4408 kB, current rate: 4096 B/s
16 ipos: 58660 MB, errors: 32, average rate: 2958 kB/s
17 opos: 58660 MB, time from last successful read: 0 s
18 Copying non-tried blocks...
19
20 The "current rate" varies and sometimes is down to a few B/s!
21 Is this normal? The drive copied to is a USB external drive.

23 Thanks for inputs.
