摘要
A method and apparatus for enabling a magnetic disk storage device that stores data according to a first data structure characterized by a fixed-length disk block size to respond to input/output requests from a host that define data according to a different data structure characterized by a different fixed-length host block size. A host adapter transfers requests and data between the host and a cache memory in the magnetic disk storage device as host blocks. A disk adapter transfers requests and data between the cache memory and magnetic disks as disk blocks. CRC data and a sector number are appended to each host block in a set of disk blocks.
