A secure media device preferably includes a Universal Serial Bus (USB) Mass Storage Class (MSC) interface and a USB Human Interface Device (HID) interface. A storage media area is also preferably provided. The storage media is preferably divided into a secure and nonsecure area by arranging the storage media into multiple Logical Units (LUNs). The nonsecure area is preferably accessed in a conventional manner using a host USB MSC driver through the USB MSC interface on the storage device. A password dialog application can be located in the nonsecure area of the storage device. A preferred method of configuring a secured storage device includes dividing storage media of the storage device into a secure and a nonsecure area. A password for accessing the secure area is preferably set using a host USB HID driver and a USB HID interface on the storage device. A preferred method of accessing a secure area of a USB secure storage device includes verifying a password using a host USB HID driver and a USB HID interface of the storage device. Once the password is verified, the secure area is preferably unlocked. After the secure area is unlocked, the storage device preferably responds to a host USB MSC driver poll with an indication that the secure area is accessible. Until the secure area is unlocked, the storage device preferably responds to a host USB MSC driver poll with an indication that the secure area is inaccessible. The secure area of the USB secured storage device is preferably locked via firmware in response to a removal or other locking event. According to various aspects of this invention, therefore, there is preferably no need for a custom driver or software package to be installed on a host computer to facilitate access to the data contained in the secure media area.
