Hi!

try it with md5sum:

$ md5sum  debian-505-powerpc-netinst.iso

$ dd /dev/cdrom bs=$blocksize count=$blockcount conv=notrunc,noerror |
md5sum

   The variable, $blocksize, $bolkcount, depend of the CD or DVD, to
get this info:

   $ isoinfo -d -i /dev/cdrom

the result must be the same.

That seems to have worked ok:

$ md5sum debian-505-powerpc-netinst.iso
86268f3a463460828ec12831d6520df7 debian-505-powerpc-netinst.iso

$ isoinfo -d -i /dev/cdrom
