Hi. I'm considering switching my recording computer to Fc5 x64 from Windows XP. My questions are... Is there any reason not to try it if I back all my stuff up? I mean, will it hurt my computer in any way to reformat and install FC5 not like it, and go back to Windows? Also: in Windows I have a partition for the OS, a partition for programs and documents, and a partition for my recording files. Should I do something similiar in FC5 and if so, how much should i dedicate to the OS(i have 72 gigs to deal with) and how do I configure FC5 to use them?
