Dug around in my screw driver collection and found a Torx 10, but it doesn't fit the screws on the back. It's supposed to be the right size, according to the instructions on Digital Home. Mine seems to be a little too big or the slots don't line up. Can't tell for sure. The site says it's a Torx 10 security screw, but I assume the word security was thrown in as an explanation and it doesn't mean there's a special Torx 10 security screw driver which is different from mine.
I posted a link to a bit set I have in another thread. I tried the T-10 security bit an it works. I suppose in a pinch you could take a regular T-10 screwdriver and cut a slot through it with a thin abrasive disk using a Dremel so it will fit.
I also see Torx security bits on amazon.ca (a lot of hardware stuff on amazon.com does not ship to Canada).
Thanks for posting all that. So, you're saying there are different Torx 10's and one is called a security bit and the other isn't even though it's also a T 10? That would explain why mine doesn't work.
LOL, I just looked up the same Wikipedia article, which was quite educational. At least now I know the security one is different.
Finally tracked down the Torx 10 security bit I need at Canadian Tire. They have a set of Torx security bits for about $15, which is in stock. Will wait for the weather to improve before walking over there, though, probably by Thursday/Friday. It's still -18C here, with wind gusts up to 60kmph.
Thanks to everyone in this thread for your help.
I can install a new 160GB stock drive for you in about 20 mins for $60, drive included. Same stock drive that came with the 8300HD. I have an extra from when I upgraded mine to a 500GB.
