Ho to copy CD's and CD-R/CD-RW'sCopying audio CD's:If you want to copy audio CD's, look for 'cdda2wav'. Be sure tu use useat least a cdda2wav-0.95beta or later. Older releases will not read correctlyfrom 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'.I recommend to write all disks in Disk at Once mode if your driveis supported in DAO mode with cdrecord. In addition, you may wish to add padding (see cdrecord / mkisofs man pages).If you want to copy such a CD directly with cdrecord, you may call:	cdrecord -v dev=... -isosize /dev/rdsk/c0t6d0s0But this may fail if the master gives read errors. To copy such a CD to a fileyou may use the program 'readcd' from this packageCall 'readcd [target] [lun] [scsibusno]' and select function 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.Recent readcd versions may be called: readcd dev=b,t,l f=outfileTo 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 'readcd'. It ignoresthe partition info and does raw SCSI reads.If you like to copy audio CD's in a way that preserves as much accuracy aspossible, use:cdda2wav -v255 -D... -Bcdrecord -v dev=... -dao -useinfo *.wavThis will preserve pre-gap sizes, indices ...
