Prime Routine
The
prime
routine performs logical block read and write operations to a specified volume with automatic retries on errors. The driver accepts either the standard 32-bit address or a 64-bit large volume address, both of which must be aligned on a 512 byte boundary representing a logical block address on the volume. The prime routine performs either a read or write command as specified by the caller.
