I've just sucessfully replaced my original 320Gig (160GB HD Box) with a 1TB Hitachi Model and thought I'd share the process with you!
My Orignal Drive is Seagate 320Gig (Yes its a 320Gig drive in a 160Gig box!)
Replacement Drive 1Tb Hitachi HDT72100SLA360 picked up from "Aria.co.uk" for around £49.00 on a special (Keep looking out for specials!)

The Process is REALLY simple !
STEP 1 - TAKE TO BOX APART
This is relatively a simple process remove the three screws at the rear and pull the whole black case (front and sides) from the rear, its a snug fit so be firm, I used a flat bladed screwdriver to prise the case forward, be careful for the "on top Switches" as these look delicate once the outer case is removed. Now remove the Screw that holds the "on top switched" on TIP- Take out the viewing card First!!
Watch out for the Lugs on each side of the front of the case -

STEP 2 - REMOVE INNER CASE
The inner case is much easier to remove, just unscrew the two side screws and then pry the metal case off, Place all the bits in a neat pile and remember where the screws came from (you don't want any pocket screws!!) you should now be left with somethink that looks a little like this -
STEP 3 - REMOVE THE HARDDRIVE
Before you start frantically takeing out screws to remove the drive caddy, take a look at the connections on the board, remove the connections to the small fan on the caddy (A bit fiddly, but be carful are its fragile!), the SATA connection (red lead) and the power lead. Once these are removed unscrew the 4 screws holding the caddy in place, you should now be left with something that looks like this -
STEP 4 - COPY THE DRIVE
Okay, so we've done the hardwork, now for the easy bit? No. Depending on you computer configuration this may be a stumbling block. My mother board has two SATA chipsets both raided and I use them, I didn't want to unplug my drives cause I know my RAID chipsets are incomplatible with SATA2 (3.0MBPS) drives which my replacement is. I bought a £15 SATA RAID controller (PCI card) and Installed it (VIA CHIPSET) plugged my new 1TB drive and the Original Drives in (Took power from a spare conneciton within the computer)then I ran Copy+ after making sure the new drive was a basic non-formatted drive. Be patient and let it do the business, make a brew and count all the screws you have!.
Be carefull using drives ouside of caddys! you don;t want to short circuit the boards!
STEP 5 - SWAP DRIVES IN CADDY AROUND
Assuming eveything has worked up to this point, swap the drives around the the caddy, the 1TB drive was thicker than the origninal but it still fits in. TOP TIP. when pacing the caddy back in the box put the "Hold Down Screws" in the caddy BEFORE placing in positon, and remember that the SATA cable goes under the caddy and not around!
:!::!:STEP 6 - OPTIONAL BUT DANGEROUS TEST
DO NOT TRY THIS UNLESS YOU ARE EXPRIENCED WITH WORKING WITH LIVE POWER!!
I got to this point and wanted to make sure everything works, so I cabled up the box and plugged the power in last of all, it all lit up and SLOWLY booted up, I gave it 5 minutes and then made sure it worked by recording 2 HD programmes at once and playing back a HD recording, it wall went fine! I powered it down, removed the power cord and un cabled it.
STEP 7 - RE ASSEMBLE
Put the SKY HD box back together again the the reverse order, The outer black case was tricky as its a snug fit, take you time as you don't want to break it.
STEP 8 - MARVEL IN YOU NEW 1TB BOX
I'm hoping its all okay at this point but a few notes that may be of some use to someone -
The replacement drive was incompatible with my motherboard, I was going to reduce the speed from 3.0mbps 1.5mbps and make it compatible to SATA not SATAII but I didn't need to do this.
I was also going to use hitachi feature tool and manage the acoustics of the drive to a quieter setting but have left it alone. Two reasons for this 1) I couldn't identify the drive in BIOS (Dead End) and 2) I it would reduce the performace and may cause a problem with the box if this was the case.
