I've had a look around for SC101 drivers for you, but can't find any Windows 7 info on it either. Hopefully Netgear will get some written sometime soon when W7 is closer to release.
I guess because it's a SAN drive and not a NAS/USB connected one, you need the management software on your PC to access it?

I've never used a SAN drive myself.
BTW, I've just seen you're from York - that's one of my favourite places! The city is a really nice place to visit, and the countryside is fantastic for walks.
