1. A method, comprising: receiving a first unit of video data of a first video on a first input/output (I/O) channel, of a plurality of I/O channels of a digital video recorder, wherein eachof the plurality of I/O channels of the digital video recorder are configured to write video data to a storage device communicably coupled to the digital video recorder; computinga first value by applying an error-detecting function to the first unit of video data prior to writing the first unit of video data to the storage device; attempting to write the first unit of video data to a first storage location of the storage device; computing, after attempting to write the first unit of video data to the first storage location, a second value by applying the error-detecting function to a data stored at the first storage location of the storage device; comparing the first and second values; and upon determining, based on the comparison and without configuring any of the plurality of I/O channels as a read channel, 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 first storage location of the storage device.
8. A non-transitory computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code executable by a processor to perform an operation comprising: receiving a first unit of video data of a first video on a first input/output (I/O) channel, of a plurality of I/O channels of a digital video recorder, wherein each of the plurality of I/O channels of the digital video recorder are configured to write video data to a storage device communicably coupled to the digital video recorder; computing a first value by applying an error-detecting function tothe first unit of video data prior to writing the first unit of video data to the storagedevice; attempting to write the first unit of video data to a first storage location of the storage device; computing, after attempting to write the first unit of video data to the first storage location, a second value by applying the error-detecting function to a data stored at the first storage location of the storage device; comparing the first and second values; and upon determining, based on the comparison and without configuring any of the plurality of I/O channels as a read channel, 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 first storage location of the storage device.
14. A digital video recorder, comprising: a processor; a plurality of input/output (I/O) channels including a first I/O channel; a storage device; logic configured to perform an operation comprising: receiving a firstunit of video data of a first video on the first I/O channel, wherein each of the plurality of I/O channels of the digital video recorder are configured to write video data to thestorage device; computing a first value by applying an error-detecting function to the first unit of video data prior to writing the first unit of video data to the storage device; attempting to write the first unit of video data to a first storage location of the storage device; computing, after attempting to write the first unit of video data to the firststorage location, a second value by applying the error-detecting function to a data stored at the first storage location of the storage device; comparing the first and second values; and upon determining, based on the comparison and without configuring any of the plurality of I/O channels as a read channel, 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 first storage location of the storage device.
