Depends on the disk. There's some you can copy with ddrescue, some |
12 |
not. Have a tail -f on the messages, you can't use dd / ddrescue / |
13 |
dd_rescue if you get stuff like this in the log: |

Note the "scrambeld sector". If you don't get those, it should work in |
21 |
most cases. If you get those, use e.g. k3b to rip an iso-image (or |
22 |
rather udf-image) of the disk, or use 'dvdbackup -M' to copy the |
23 |
data. There's some "broken" disks though with intentional defects in |
24 |
the filesystem etc., often from Fbal. You usually won't be able to |
25 |
copy those "whole" and images witk k3b will probably be |
26 |
defective. Using dvdbackup, dvdcpy, lxdvdrip, mplayer, tccat or so to |
27 |
copy only the titles that you actually want (main feature, extras, but |
28 |
e.g. no trailers and stuff) will be the only way. |
