Abstract
Systems, methods, and computer program products to perform an operation comprising receiving a first unit of video data on a first input/output (I/O) channel, of a plurality of I/O channels of a digital video recorder, computing a first value by applying an error-detecting function to the first unit of video data, attempting to write the first unit of video data to a storage location of a storage device communicably coupled to the digital video recorder, computing, after attempting to write the first unit of video data, a second value by applying the error-detecting function to a data stored at the storage location of the storage device, and upon determining that the first and second values are not equal, storing an indication that the first unit of video data was not successfully written to the storage location of the storage device.
