Abstract
Embodiments described herein disclose methods and devices for expanding the storage capacity in a storage device, including the steps of: creating at least one partition in a storage memory of the storage device; designating a reserved-storage area and an enabled-storage area in at least one partition; storing a partition size in a FAT of the storage memory; and upon authorization, increasing the partition size to include sectors in the reserved-storage area, thereby expanding the storage capacity in a storage device. Preferably, the reserved-storage area is not accessible by a host system. Preferably, the partition size is determined from a partition range stored in a master boot record in the storage memory. Most preferably, the partition range is determined from an enabled capacity stored in a memory-management area in the storage memory, and wherein the memory-management area is not accessible by a host system.
