Как проверить cd/dvd уже после записи?

md5sum /dev/sr0

C dvd не прокатит. Там есть служебка.

Отвечая на свой же вопрос:

if test «$blocksize» = ""; then
echo catdevice FATAL ERROR: Blank blocksize >&2
exit
fi

echo «block size: $blocksize»
echo «block count: $blockcount»

#Command for reading disk
raw_read_command=«dd if=$DEVICE bs=$blocksize count=$blockcount conv=notrunc,noerror»

#Getting checksums
echo «Reading CD and creating check sum...»
$raw_read_command | md5sum > $MD5SUM_CD
echo «Reading ISO and creating check sum...»
md5sum $IMAGE_FILE > $MD5SUM_ISO

# Comparing md5 checksums
echo «Comparing check sums...»
cat $MD5SUM_ISO | while read CODE NAME; do
if [ -n «`cat $MD5SUM_CD | grep $CODE`» ]; then
echo «Success: $NAME»
else
echo «Failure: $NAME»
fi
done

#Cleaning up
rm -f $MD5SUM_CD $MD5SUM_ISO

Все же просто:

И никакой консоли.

Я несколько дописал тот скрипт :)
