Thank you Joerg, I had two CD drives in the PC I tried previously. readcd was |
13 |
clever enough to identify the drive with the CD in it, but I specified the |
14 |
device on the command line just to be sure, following the man page. |
15 |
|
16 |
This time I tried using a different PC with a single CD drive: |
17 |
|

# readcd -scanbus |

There are no visible scratches on the disk, so I am thinking this is not a |
103 |
mechanical fault, but something to do with the burner. I am glad that I |
104 |
learned about readcd, but given the above results shall I give up hope and ask |
105 |
the guy to burn me a new CD using a different burner this time? |
