Call me a thick newbie if you like.

I have just installed HDRX12_3.0 20050524 on to my 300GB Seagate.
Initially, I did not have much success due to DriveReady SeekComplete errors, UNTIL I found a posting that Darren King had articulated the exact steps to follow. Still not sure I have a faultless install yet, although it did come up with the amount of available recording time at the end. I understand that means I'm OK.

Anyhow I am now ready to install the hard drive into to my HoboTech TiVO but damned if I can work out how to get the cover off. I did manage to get the front plastic panel off. Thinking that this would show me the way, I am still stumped. Not a screw head to be seen anywhere!

I have searched the forum + Google but still no clues. What can I not see that is before me very eyes?
