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 alternative information storage architectures, and thereby, to increase the capacity utilization of data storage media.
A method to increase the storage capacity of a data storage medium, comprising the steps of:
A data storage and retrieval system comprising a computer useable medium having computer readable program code disposed therein for increasing the storage capacity of a data storage medium movably disposed in said data storage and retrieval system, wherein said data storage and retrieval system comprises a host computer, an operating system, and a first data storage device comprising a fixed device architecture, wherein said first data storage device is capable of operating in a default capacity mode or in an extended capacity mode, wherein said first data storage device is capable of switching between said default capacity mode and said extended capacity mode, and wherein said default capacity mode utilizes a 22 bit blockid format and said extended capacity mode utilizes a 32 bit blockid format, the computer readable program code comprising a series of computer readable program steps to effect:
A computer program product comprising a data management system usable with one or more computer processors disposed in a data storage and retrieval system, said computer program product having computer readable program code embodied therein for increasing the storage capacity of a data storage medium, wherein said data storage and retrieval system includes a first data storage device having a fixed device architecture, wherein said first data storage device is capable of operating in a default capacity mode or in an extended capacity mode, wherein said first data storage device is capable of switching between said default capacity mode and said extended capacity mode, and wherein said default capacity mode utilizes a 22 bit blockid format and said extended capacity mode utilizes a 32 bit blockid format, comprising:
