Advertisements My Edge is already out of warranty i am being told as it was supplied as a replacement for my bolt (been through 3 of them) always a hard disk issue. In any case i bought a new drive and was ready to put it in. The screws in the bottom of the Edge tivo are a reverse (male) Torx 30 head. I looked for days for a driver that would accomodate but could not find one other than Weaknees.com but they want to sell you the whole drive kit that comes with the tool. So heres what i did. Went to Home Depot and fond a large screw with a Torx 30 (female head obviously) head. I ground down the outside until it fit fine into the recessed hole and then screwed it into a block of wood (the handle). Works great, removed the screws in a few seconds.
