Abstract
A storage management system, apparatus, and method to increase the storage capacity of data storage media. Applicants' method uses a data storage device comprising a fixed device architecture, where that data storage device is capable of operating in a first capacity mode or in a second capacity mode, and where that data storage device is capable of switching between the first capacity mode and the second capacity mode. In certain embodiments, the first capacity mode utilizes a 22 bit blockid format and the second capacity mode utilizes a 32 bit blockid format. In other embodiments, the first capacity mode utilizes a 32 bit blockid format and the second capacity mode utilizes a 22 bit blockid format.A computer code product comprising a data management system which includes an operating system and data storage device microcode, which supports the capability to switch between alternative information storage architectures, and thereby, increase the capacity utilization of data storage media.A data storage and retrieval system comprising a computer useable medium having computer readable program code disposed therein for implementing Applicants' method to switch between use of alternat…
