I've got a 4.4R ISO file. Size is 324368*2048. I did "burncd -f /dev/acd0c -s 8 data 4.4R.iso fixate" and then did "dd if=/dev/acd0a bs=2k | wc" which showed the CD was one 2048-byte block bigger than the ISO file. I used "dd" and "md5" to verify that the first 324368 blocks of the CD were the same as the ISO file. Why the extra block? Also: Is there ANY difference between /dev/acd0a and /dev/acd0c between the name and the minor number? May they always be used interchangeably?
