The assumption that all the disk world is thinking in 512-byte records is wrong, too. It's even possible for regular (type 0) disks to be formatted to almost any record size, but the entire matter starts getting annoying for media where you can't change the record size like magneto-optical disks that are often available with either 512 or 1024-byte records. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
