As the title says, readcd always fails when I try to copy a CDR
prepared by cdrecord and mkisofs. I use both the simple command
"readcd dev=0,0,0 f=cdrom" and the added option "-clone" (sample
output appended below). The files in the CDR, however, are free
from any data error, when I check them against the original files
using "diff" or "md5sum".
The trick is to read only what you wrote. If you use isoinfo -d
you can see the size of the ISO filesystem. Then use
"sectors=0-size" to read only that much back. You also want to
burn -tao, that is reported to help default behaviour without
the need for sectors=.
The problem is that with one drive I could only burn -tao. CDR's
burned with -dao (on my other drive) are read successfully with
readcd.
If you do what I suggested and get the size of the f/s, then read only that
size, it doesn't matter. At least on any media and burner combo I've tried,
up around 14 I use at least monthly.
