My daughter just finished building my new computer and is starting to install Windows and I need to make a decision right now on partitioning a part of the hard drive to use as the scratch disk for CS6.

Before I was using an external 500GB HD as a scratch disk. Is it better to partition my 2 TB main HD or is it ok to still keep using the external? If I should partition, how much should I allot for it?? 500GB still?

If anyone can answer asap that would be super! My daughter and I are standing by ...
