Do you see any downside to allocating say 30Gb to C: to allow for Programmes, drivers & games etc together, or is it much better to separate up the games?
As I stated before, I may run my computers a little differently than other people. If you think you need 30Gbs then by all means allocate the space. The idea behind partitioning is to get the data off the OS partition so if you can at least do that, you'll be ok. I still can't imagine the sizes you state for Windows and Program files though, but perhaps its due to Media Center. Not sure. If you run Aida32 and view Installed programs, you can list/sort the programs by size. Not all programs will show the size, but it'll give you some idea. Also, the free Spacemonger
will show you the exact size of each catagory/folder/program on your computer. Neat application. By all means, allocate what you think you need. You're the user, so, I can only recommend things.
When I say 'retain the drives', I'm wondering if we can just back them up and put them onto the reformated drive, or is it necessary to load fresh ones? I notice you think they may be contained on the Philips Rescue Disc, but if they are, they'll be older versions I imagine.
That's what I thought you meant, but wasn't sure. Yes, back up the drivers so you can install them later. You don't need to download any fresh ones if the ones you have are current. Just back them up on a flash drive or something until you need them.
