Abstract
Systems, apparatus and methods are disclosed for testing performance of a disk drive in a digital home communications terminal. One such method comprises: downloading a disk drive performance test application from a server over a communication channel; executing the test application to measure at least one time for data transfer of a group of sectors on the disk drive; and reporting the time to the server over the communication channel. A digital video recorder comprises: a disk drive; a communication interface; memory storing executable instructions thereon; and a processor configured by the executable instructions. The processor is configured to download a disk drive performance test application from a server over the communication interface; execute the test application to measure at least one time for data transfer of a group of sectors on the disk drive; and report the time to the server over the communication interface.
