A correct diagnosis is _essential_ to fixing problem. It has nothing to
do with md5sum:

{pts/1}% dd if=/dev/scd0 of=test.iso bs=1k
dd: ������ `/dev/scd0': Input/output error
54856+0 ������� �������
54856+0 �������� �������

dmesg ->

 I/O error: dev 0b:00, sector 109712
 I/O error: dev 0b:00, sector 109712

it seems that something evil happened with the way cdrom driver handles
EOF. The resulting image seems O.K. and can be processed normally; CD
itself is also O.K.
