I just want a concensus to the size of everyones partition for vista. I am going to dual boot xp pro and vista 64. I made xp 45gb because I will not be putting a lot of info on that partition. I was wondering what you thought a good size for vista will be? I was thinking around 100-120gb. I have many large programs to install like adobe CS3, office 07, etc that take up a lot of space. I want to future proof it for size. What is your take on this?
I have seen some people say 20gb. Do you not put anything on this partition? That seems so small.

yeh that's pretty good. My Vista partition is 112 GB. I have that CS3 suite installed, Office Home and Student 07, Encarta Student, VS C# Express 2008 and C++ Express 2008, the general "must-have" programs like Winrar and Firefox among others, and some gigs in downloads and documents / files. I still have about 40 odd gigs left free on C:

Although, you should note that I have a different partition for media, which can gobble up free-space quite fast if you plan on having any.

With the two hdd I plan on xp on 45gb, ? on vista yet and left over space on this same drive as music. The other 500gb hdd will be documents, video, and pics etc.

If it's just music you should be fine. But if you're like me and use MCE to record shows and are just too lazy to transcode them, be prepared to sacrifice an entire disk to them. Right now I'm in the process of getting a 500GB drive cuz my current media drive is full.

Also, I would advise you pre-plan how you are going to partition those drives beforehand, and make sure you have an allowed configuration in mind. When I was partitioning mine I jumped right into it and didn't know there was a limit to each different types of partition, and that only certain configurations were allowed. As a result I have 18GB of unpartitioned space because I can't be bothered to repartition that drive again (partly for fear of data loss, and the rest because I'm too plain lazy).

Just to give you an idea, my laptop has a 100GB hard drive (well, 87 after marketing scams and a recovery partition), and with Vista Ultimate, VS 2008 Team Suite, Office 2007 Ultimate, a handful of other small programs and about 25GB of music I still have 15GB left over.

I have 3 partitions on my main drive and only one on the other. My vista is at 50gb as I am only putting the os and several small apps on this drive. All the other apps are on my other separate drive. My problem is that somehow the vista drive keeps filling up and I don't know why. I can't find anything that is adding up to 41gb that it says it is full of. Where could it be?

i suggets no less that 100G for vista Microsoft suggest 40 for ultimate, but base on what you plan to run and bare in mind the pagefile it will create.

I have only small programs on the C: drive. I have found a 14gb temp folder in windows. Can I not move the page file?

yeah you can locate the page file to a different drive that what the opeating system is installed on

I had talked to people and so many have made vista only 40gb or even less. What am I doing wrong that I have this happening? I also found a file called winsxs. It is packed with amd64 stuff. Does everyone have this?
