The weaknees warranty maybe up however the maxtor warranty may not be (some maxtor drives have 3 yr. warranties others 1 year). If you are willing to open your box up you can check it at:

This is a quote from the weaknees warranty page:
"Many of our newly-installed TiVo hard drives come with a full manufacturer's warranty, which is generally one to three years. Some of our drive kits use OEM drives which have our six-month warranty only. If your drive fails after our six month warranty, but before the manufacturer's warranty (if existent) is over, we will help you exchange the drive quickly for a service charge.*"
Kind of sucks that weaknees doesn't warranty their imaging of the drives for as long as the manufacture warranty.
In regards to not using your Direct TiVo much - it is being used continually because of the 30 min buffer so as long as its on, its recording to the hard drive.
