Abstract
Disclosed herein is an improved sector remapping method that maps logical sectors into physical sectors in storage disks such as SATA (Serial ATA) drives without reducing either storage capacity or I/O performance efficiency. Under this sector remapping method, logical sectors of data can be written into the physical sectors of a storage device through control frames having padded data or information associated with the padded data, as well as data frames having real data to be stored. With the padded data to be added to the real data, the frames provide multiple physical sectors to be transmitted into the storage device in a single write operation. The sector remapping method can be implemented in a storage bridge coupled to a storage device such as SATA drives.
