The option -t random specifies that "the block should be filled with a random bit pattern".
Now, just how random is that bit pattern. Does it choose a random byte and fill the entire hard drive with it? Does it make up a random disk block and write that to the whole disk? Or does each block get its own randomly chosen data, presumably generated by a pseudorandom generator so as to catch bad seeks? In this case, is the seed always the same, so I could take a disk I wrote on with -t random and check it next week, the computer being off in between? -- hendrik -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
