Hi folks,

can you show me how to compare (checksums of) CD-R versus its original iso
image (used to be copied to /mnt/cd/wd)?
I don't know how to access the raw data on the CD  (I feel that it should be
some trick with with /dev/sdC1/ctl or  /dev/sdC1/raw ... )


Also, I've got trapped in (presumably easy to write) script to compare all
files in two (intentionally identical) directories. Just something like cmp
filelist1 filelist2. I ended up with ugly enough catting everything together
and piping it to cmp   :-(((
Beg for your help here, too. I must be an idiot, or what.


Cheers,
++pac.
