Portable data storage device allowing dynamic setting of disk type and the method of dynamically setting disk type thereof

摘要

A portable data storage device allowing dynamic setting of disk type thereof includes a flash memory that includes at least two segments preset as a CD-ROM segment and a fixed type hard drive segment. When the portable data storage device is plugged in a processing unit of an electronic apparatus, one of the two segments having a non-applicable disk type is hidden depending on an operating system under which the processing unit operates, so that the processing unit may detect only another one of the two segments that has an applicable disk type. A method for dynamically setting an applicable disk type of the portable data storage device is also provided.
