200 GB is probably unnecessarily large UNLESS you install a bunch of games on C. They tend to take up a lot of space.

An ordinary Windows 7 installation with 20 or 30 random applications is probably under 40 GB. I don't often hear of even 100 GB being used unless a lot of games are involved.

Once you install Win7 to the new HD you can also plug back in the old HD, then once you're sure you have everything off of it or don't need to boot XP any longer open an Elevated Command Prompt to run the Diskpart Clean command exactly as given here: Clean and Clean All with Diskpart Command

Don't worry, it won't let you Clean the Win7 HD!

Then you can open Win7 Disk Management and it will let you partition the old HD as you want: Partition or Volume - Create New

Windows 7 Ultimate x64

Thanks a bunch everyone.
I have one more question, because my plans have changed slightly, due to incompetent "professional" ebay sellers who sold me each in turn 500GB Caviar blue HD and one week later I got refunds 2 days apart. (they had 200 and 45 pcs in stock!!) So it goes...
Meanwhile a friend was telling me that I should get an SSD and I found one in my budget, I found 30GB PCI slot.
My question is Is 30 GB enough just for W-7?
All my music software take little space, NO sound libraries etc...
If it is not enough, I can go back to XP but I want to put XP on the SSD, which will create a problem? 2XP on 2 discs?

I would not want an SSD that small to run Win7 with its programs, and I would not want to move programs to a slower HDD to defeat an SSD's purpose.

Let's see what others think.

I agree with Greg. I would go fo at least a 64GB. That is what I have and am currently using 30GB with user files and games on a spinner. 64GB is plenty if you manage it right.

30GB for a SSD is too small for Windows 7. Initially you may be able to fit in the Windows 7, but you will run out of space very soon. Like Greg said it will defeat the purpose of going for a SSD.

In my system (no SSD and a spinner with 640GB), I allocated 80GB for C: with typical space usage values for OS (approx 17.5GB), applications folder (approx 9.75GB), Users folders (approx 0.7GB), pagefile (approx 3GB) and a breathing space on C: drive. I don't have any heavy applications except for MS Office 2003 and Adobe Acrobat 9.0.

A 30GB SSD should be OK for Windows XP but not for Windows 7. I was managing with a 20GB partition comfortably for windows XP earlier but now my C: partition with windows 7 is 80GB with about 33GB already used.

I recommend you to have a comfortable size of about 80-100GB for a SSD.

Yes you're right, I googled around and 30GB just isn't enough, and I would probably regret it in a few months...
And plus "they" say that an SSD should not be "full", max 60-70%...
A 60GB is a couple bucks more...

Cheers and thanx for help
