== Tips == |
|||
=== Backup cdrom === |
|||
Here a script I use to backup cdrom on Linux, named {{file|ripcd.sh}}. |
|||
* Use '''cdrdao''' for raw extraction. |
|||
:* extra AUDIO tracks. |
|||
:* extra MODE2 tracks. |
|||
* Use [https://github.com/claunia/edccchk edccchk] to check ECC/ECD on raw image |
|||
:* Make sure raw image has no ECC/ECD warning/error (if so, better extract ISO to have errors corrected). |
|||
* Use [https://github.com/xeyownt/raw2iso raw2iso] ([https://github.com/not-a-user/raw2iso original]) to convert raw image into iso file. |
|||
* Compare files on ISO with those on cdrom. |
|||
;Limitations: |
|||
* Note that some CD may have extraction errors in the 2s lead out (150 last sectors). This is normal. |
|||
* Sub-channel extraction (<code>rip-cdrdao-raw-sub</code>) does not work. At least, it does not produce same data as CloneCD. |
|||
;rip-dd |
|||
* The <code>rip-dd</code> function in the script (not used) work around that by extracting only the data part, excludind that lead out track. |
|||
* Note however that <code>rip-cd</code> does not make a complete rip (ignore audio tracks for instance). |
