Yes. Drive actuators are (or used to be) typically rated for at least 50,000 load-cycle counts; at ~1000 events per day, there's about a 50% chance of such a drive dying before two years are up: http://en.wikipedia.org/wiki/Hard_disk_drive#Landing_zones_and_load.2Funload_technology Some models of drives intended for laptops (typically smaller 2.5" form factor w/ single platter) can tolerate many more load-cycles, and newer drives also claim to handle more.
