ABSTRACT:
A tape drive emulator (30) is between a host computer (40) and a removable disk drive (22) and appears to the host computer 40 as a sequential storage system, e.g., a tape drive. However, the tape drive emulator (30) processes the data obtained from or applied to host computer 40 so that the data can be communicated to removable disk drive 22 in a manner compatible with a conventional removable disk drive. Yet in so doing, tape drive emulator 30 imposes on the data (1) an data organization, imperceptible to disk drive 22, for rendering the data expressable and locatable in a tape drive format, and (2) an additional degree of error correction that provides enhanced data integrity necessary for data backup/restore operations.
