Problem

Solutions: Disk Controller: Electronics that mediate the transfer of data between disk drives and the computer's memory.

A controller is an actual circuit board which plugs into the computer's expansion bus. Its purpose is to follow through instructions given from the computer to the hard or floppy drive and report back to the computer. The controller also controls the hard disk's speed of interleave. Interleave is the ratio of physical disk sectorson a hard disk that are skipped for every sector actually used for write operations. If the interleave factor is 4:1, (four to one) the disk writes to a sector, skips four sectors, writes to a sector, skips four sectors, and so on.
