Upgrading sky box hard drive

[Sacramento]

Hi folks
Could anyone please tell me how to go about fitting a larger hard drive into a Sky+hd box. Is it easy enough to do?
I find the existing one too small. I go away for a few weeks for work and when I come back it's usually full. Also getting technical faults on some recording failures, suspect the drive is maybe breaking up as have had to do the rebuild thing 3 times recently. Any help and advice greatly appreciated.
Box is an Amstrad as supplied by Sky, just about 2 years old and I was told by Sky that it has a 500GB drive, then they tried to sell me a 1TB box for £150, maybe this would be cheaper than doing an upgrade?
Any thoughts, ideas please?

Thanks

Steve
