Try to read the man page and use the direct access to the related functions. |
55 |
|
56 |
From your printout, I cannot even tell whether the device argument was correct. |
57 |
|
58 |
Start with readcd -scanbus |
59 |
|
60 |
If you continue with readcd dev=xxx (only needed at all if you have more than |
61 |
one CD like drive), you could e.g. try readcd f=out-file -noerror |
62 |
|
63 |
If your drive cannot read the toc or otherwise believes there is no medium, |
64 |
readcd cannot help. You need to check why the toc cannot be read. If the CD ic |
65 |
scratched, then try to use Plexiglass polishing paste. Be carefull to prevent |
66 |
polishing paste to slip to the paint side and to let the CD move on the paint |
67 |
side. |
