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 'icedax'.
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 'readom'.
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'.
I recommend to write all disks in Disk at Once mode if your drive
is supported in DAO mode with wodim. In addition, you may wish to
add padding (see wodim / genisoimage man pages).
If you want to copy such a CD directly with wodim, you may call:
wodim -v dev=... -isosize /dev/cdrw
But this may fail if the master gives read errors. To copy such a CD to a file
you may use the program 'readom' from this package
Call 'readom [target] [lun] [scsibusno]' and select function 11.
Or call readom -help to get alternate usage.
To prevent readom from reading the run-out sectors, reduce the
number of sectors to copy by 2.
Recent readom versions may be called: readom dev=b,t,l f=outfile
To reduce the numbers of sectors to copy you may use the sectors= option.
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 'readom'. It ignores
the partition info and does raw SCSI reads.
If you like to copy audio CD's in a way that preserves as much accuracy as
possible, use:
icedax -vall -D... -B
wodim -v dev=... -dao -useinfo *.wav
This will preserve pre-gap sizes, indices ...
