Abstract: Improved techniques for rendering a peripheral device removable (e.g., unpluggable) are disclosed. According to one aspect of the invention, the peripheral device is rendered removable from a host computer without preparatory user actions. In effect, the peripheral device can be automatically prepared for removal in the event that its user removes (unplugs) it from its host computer. According to another aspect of the invention, the peripheral device includes a data storage device that is mounted to a file system of the host computer when the host computer desires access to the data storage device. Otherwise, the data storage device is normally unmounted so that if the peripheral device were to be removed (e.g., unplugged) no harm or damage to data stored therein would occur. These aspects of the invention can be utilized alone or in combination with one another. The invention is particularly well suited for peripheral devices that are media players which are nullhotnull unpluggable without detrimental consequences.
