Abstract: Methods and devices for enabling compatibility of media storage devices with a wide range of external devices are generally provided herein. More specifically, methods and devices disclosed herein allow a single media storage device to be accessed by external devices that are incapable of accesses the same file structure(s) and/or file type(s). A media storage device may include a plurality of logical units, each with one or more partitions. A file system on a first partition of a first logical unit may be selected for compatibility with one external device, while a file system on a second partition of a second logical unit may be selected for compatibility with a second, different external device. The media storage device may present as a fixed disc for further interoperability.
