Just got home from assisting a friend build his PC. Everything was successful and he's up and running. Windows 7 was installed on an SSD (http://www.scan.co.uk/products/60gb-corsair-force-serie...) with a 1TB Spinpoint F3 as storage. The F3 get's power and is recognised perfectly in Device Manager, however does not show as a storage drive inside My Computer.
It has puzzled me a little bit, I am wondering if the drive requires formatting before it will get recognised.
All you need to do is to go into Windows, right click on the "My computer" icon on the desktop, click manage. Then it will go into the computer manager - from there go into Disk Management, choose the drive - format it (if need be) then assign a drive letter and you should be good to go.
