About booting games off a HHD using a Matrix Infinity

[Cyber Akuma]

Ok, I got my drive (Segate ST3500641ARK, 500GIGs) and network adapter, and now I have two new problems.

1. As I was putting it in I realized something, I have no caddy/tray for it. While I can still fit it in the slot, I am worried about it coming loose or short-circuiting from the bottom of it coming into contact with the metal bottom of the HDD bay. I checked my official drive and the tray makes it fit peftectly in the slot as well as insulate the bottom of the drive. Where can I get one of these trays, caddies, whatever they are called without buying the entire HDD with it? Is it a risk?

2. I cannot seem to get the HDD utility program to work. I am using version 1.10, and it just hangs on the following screen:
Checking the HDD.
Wait a moment

Yes, the ATAD patch on my MI is enabled, without it the HDD Utility cannot even tell that a harddrive is connected.

Any help?
