I agree with eneles, the only way to increase the HDD capacity is either by replacing the current HDD or by using an external one. As far externals go, try this: http://www.scan.co.uk/Products/Produ...oductID=296949 or, if you prefer to upgrade the internal one, try this: http://www.scan.co.uk/Products/Produ...oductID=559214.

If you want to upgrade the internal drive, you'll need to image the disk onto an external drive, using Ghost or some other equivalent software.

If all you need is more space, I'd go for an external drive and wouldn't have to worry about imaging.
