Abstract
A disk can store data from two different operating systems, particularly DOS and MAC OS formats. The initial sector on the disk, sector zero, is divided between the operating systems, allowing two sector signatures. As a result, DOS recognizes the disk as valid and the MAC OS can support a driver on the disk. According to another aspect of the invention, the DOS portion of the dual-format disk is reclaimed by having a software program start its execution on the dual-format disk then switch its execution to another storage device. As a result, the program can dismount the dual-format disk and safely reclaim it for use on the MAC OS.
