I was trying to determine a md5sum from a DVD I had inserted into a FreeBSD 8.0 on my Dell Inspiron 9400 notebook. I thought dd if=/dev/acd0 | md5 would work but I got "Invalid argument". Trying dd if=/dev/acd0 bs=1048k | md5 worked in so far that it didn't yield an error but after the DVD stopped spinning the command hung and I only could bail out using ^C. Any clues? -- Christoph
