Abstract
A memory cache device for a CD-ROM for use with a host computer capable of initially filling a clone area of the hard disk with data from the compact disc using a sequential striped fill process for copying a plurality of blocks of data from the compact disc to the hard disk, the process comprising the steps of: accessing a first block of data of a sequence of data blocks from the compact disc and copying the first block onto the hard disk, accessing a second block of data in the sequence of data blocks from the compact disc and not copying the second block to the hard disk, and accessing a third block of data in the sequence of data blocks from the compact disc and copying the third block onto the hard disk, the fill process continuing until the entire capacity of the hard disk devoted to cloning the compact disk is full, while leaving sufficient area for storage of blocks not initially copied in the fill process.
