A corrupt sector corrupts the remaining part of the block. Block sizes are much smaller than 1 GB because when part of a block is changed, all the following bytes have to be rewritten (if a reasonable the cipher mode is used). By the way, the very fact that the block is not lost completely indicates a major cryptographic weakness: there are no integrity checks at all. (The constant IV problem is another one.) These weaknesses don't matter in many scenarios, but it's still an undesirable situation. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
