Abstract:
A method of operating a disk drive having a cache memory wherein the disk drive is connectable to a host computer for reading and writing data on a disk, the method comprising the steps of:defining a length parameter specifying the length of a data segment to be written to the disk; defining a first portion of the cache memory for storing a data segment whose length is equal to the length parameter; defining a second portion of the cache memory for storing a data segment whose length is not equal to the length parameter; receiving a host write command including a write data segment having a write command length; storing the write data segment in the first portion if the write command length is equal to the length parameter; storing the write data segment in the second portion if the write command length is not equal to the length parameter, and delaying writing the data segment on the disk according to a predetermined delayed writing policy.
