I had bought a SLACKWARE-LINUX-10.0 distribution.
------------------------------------------------------
I cloned the disk nr. 3 using:
#readcd dev=0,0,0 -clone -f=slack3
#cdrecord dev=0,0,0 -raw96r -clone -v slack3
#mount /cdrom
#cp -a /cdrom/slackware-book .
#cp: reading `/cdrom/slackware-book/Slack8Book_files/image013.gif': Input/output error
#ls -l slackware-book/Slack8Book_files/image013.gif
-rw-r--r-- 1 root root 8192 2004-09-19 13:15 slackware-book/Slack8Book_files/image013.gif
-------------------------------------------------------
Now I cloned the disk nr. 3 using:
#dd if=/dev/cdwriter of=slack3
#cdrecord -v speed=8 dev=0,0,0 slack3
#mount /cdrom
#cp -a /cdrom/slackware-book .
/* no input/output error signalled */
#ls -l slackware-book/Slack8Book_files/image013.gif
-rw-r--r-- 1 root root 25962 2002-03-29 21:50 slackware-book/Slack8Book_files/image013.gif
-------------------------------------------------------
Conclusion: using 'readcd' plus 'cdrecord' seems to be
error prone.
