It wasn't that chicken-and-egg situation that I was referring to, but the long standing issue that the self check has been bad for a very long time. If *something* *else* can manage to not read past the end of the disc, why can't it? In this circumstance, the checksum doesn't present that sort of problem, because it's a fixed size. You know how many bytes it's going to use, even if you didn't know what bytes would be in it. So, you could certainly include the checksum on the disc and still have a known disc *size*. The chicken and egg problem of how do you put a checksum onto the disc that you're going to checksum only has one simple solution: Don't. You'd have a routine that asked for a checksum to be inputed, from some other source, and the disc to be checked against it. -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored.
