As mentioned, the high level error correction in readcd can only help when the |
| 56 |
drive does not include a decent Reed Solomon implementation in it's firmware. |
| 57 |
|
| 58 |
What you could do is to check other sector ranges to find out whether the hole |
| 59 |
capacity of the CD is unreadable or whether there are readable parts inside. |
| 60 |
Note however that if you come close to the outer edge of the CD (1-2cm) the |
| 61 |
error rate usually increases. |
| 62 |
|
| 63 |
check the sectors= option in the man page... |
