Essentially what I want to know is, has ddrescue made any progress? Is my hdd pretty well dead?After executingsudo ddrescue -d -r3 /dev/sdb dos_pace.img dos_pace-ddrescue.logon a USB 2.0-enclosed drive, I've gotGNU ddrescue 1.19Press Ctrl-C to interruptrescued:         0 B,  errsize:   1376 MB,  current rate:        0 B/s   ipos:     1083 MB,   errors:    4170,    average rate:        0 B/s   opos:     1083 MB, run time:    4.10 h,  successful read:    4.10 h agoCopying non-tried blocks...
