摘要： A playback device includes a port configured to receive content from an external memory device, a device memory residing in the device, and a controller programmed to execute instructions that cause the controller to read a read data pattern from the defined region in the external memory device and determine if the read data pattern correlates to an expected data pattern to a predetermined level, wherein the expected data pattern is derived at least in part from a defect map of the defined region.
