Leopard Sample Code: Hardware & Drivers
Mass storage devices run the gamut from the fastest read/write peripheral disk drives to sequential-access tape drives. Mac OS X provides a layered mass storage driver stack that has built-in support for common industry-standard devices. Developers can use the BSD interface and I/O Kit APIs to access storage devices and their media at different layers of the stack.
