Subj : ddrescue To : ALL From : Dumas Walker Date : Mon Feb 08 2021 03:45 pm I have been trying to use ddrescue to make a good copy of a DVD that only works in some of my DVD players. I actually got it to work with one DVD, but the other one gets so far and then, after several hours, the screen looks like this: *** # ddrescue -v -b 2048 -r 4 /dev/sr0 D1.iso D1.log GNU ddrescue 1.23 About to copy 7255 MBytes from '/dev/sr0' to 'D1.iso' Starting positions: infile = 0 B, outfile = 0 B Copy block size: 32 sectors Initial skip size: 64 sectors Sector size: 2048 Bytes Press Ctrl-C to interrupt ipos: 4415 MB, non-trimmed: 360116 kB, current rate: 0 B/s opos: 4415 MB, non-scraped: 0 B, average rate: 79775 B/s non-tried: 1716 MB, bad-sector: 0 B, error rate: 8192 B/s rescued: 5179 MB, bad areas: 0, run time: 18h 2m pct rescued: 71.37%, read errors: 5569, remaining time: n/a time since last successful read: 16h 30m 43s Copying non-tried blocks... Pass 5 (forwards) *** Note that the last successful read time is over 16 hours. At this point, the numbers in the left column have long since quit incrementing, while the numbers (that are not 0) in the other two colums are the only ones going up. I have searched on the internet about this. Some folks talk about theirs going days without ever stopping on its own. Others point out that sometimes you can CTRL-C out and the iso you get will be mostly OK. Mine unfortunately was not. :) Is there anything I should think about changing on the command line to get better results? * SLMR 2.1a * I am Popeye of Borg.
