The R-Driver package also, by the way, contains a 77mm mini-CD driver disc, which may be of use to Win98 users, or may not; my devotion to journalistic excellence is insufficient for me to bother checking. Everyone using vaguely recent versions of Windows or Mac OS shouldn't need any extra drivers to use any modern ATA/USB adapter; USB storage drivers are built into the operating system. Linux ought not to be a problem either, but that depends on the bridge hardware chipset in the adapter cable, the Linux version you're using, and possibly also the thread count of your bedsheets.
