The clean install is of course clean. http://www.tomshardware.com/forum/254829-32-cloning-smaller-drive covers more as well as my old favorite shrink (GPARTED) and CLONE.

I would like to replace my boot 7200 rpm WD hard drive with a new 10000 rpm Velociraptor WD hard drive. I was going to clone the drive but the device we have at work will not clone from the 1TB drive to the smaller 600GB drive. Is there freeware available or should I pay for software? Should I just go ahead and reinstall the os on the drive. I have a windows upgrade disc from vista and I have all of the applications to reinstall.
