Abstract
A method for detecting errors in streaming media devices is described. In one embodiment, when a command to write a block of data to a streaming media device is received, integrity metadata associated with the data block is attached to the data block and written to the streaming media device together with the data block. Subsequently, when a read command pertaining to this data block is received, new integrity metadata is determined and compared to the attached metadata. If the new integrity metadata does not match the attached metadata, an error message is generated.
