This bloody software is running for over 3 days straight now (I'm now at 79%; first 60 went ok then went really slow). It's using roughly 34% cpu power continually on my 3,2ghz quad core. There's only one disk in my system and I have roughly 3gb left (from a total of 1tb). I did read the message after pressing start that says it will take longer if you have this low amount of space left but still, this is just ridiculously slow. Any advice?
