- Ho to copy CD's and CD-R/CD-RW's
- Copying audio CD's:
- If you want to copy audio CD's, look for 'cdda2wav'. Be sure tu use use
- at least a cdda2wav-0.95beta or later. Older releases will not read correctly
- from SCSI-3/mmc compliant drives.
- Copying data CD's:
- The best way to copy a data disk is to copy the raw data on the master CD.
- This may be done by reading the data from the raw device by using 'dd' or
- 'sdd'.
- NOTE: All CD-R's written in Track At Once mode end in two unreadable
- run-out sectors. If the disk has been written with a Yamaha CD-R100
- or with a Yamaha CD-R102, there are even more run-out sectors.
- For this reason, you will not be able to read such a CD correctly with 'dd'.
- If you want to copy such a CD directly with cdrecord, you may call:
- cdrecord -v dev=... -isosize /dev/rdsk/c0t6d0s0
- But this may fail if the master gives read errors. To copy such a CD to a file
- you may use the program 'readcd' from this package
- Call 'readcd [target] [lun] [scsibusno]' and select funtion 11.
- Or call readcd -help to get alternate usage.
- To prevent readcd from reading the run-out sectors, reduce the
- number of sectors to copy by 2.
- If the master disk is made of several partitions (like a Solaris boot CD),
- the best way to copy a CD is to use the program 'readcd'. It ignores
- the partition info and does raw SCSI reads.
