Hello, I am trying to partition a drive on a new laptop as many seem to recommend doing so. yet others advise against it. So, two questions: 1. Using Windows 7 Disk Management tool my 700GB HDD can only be shrunk to 336GB...which is strange for a brand new drive. Also 336GB is too much for the OS drive. Any ideas on why W7 Disk Management is giving me this restriction. Any tips? 2. Do I really need to partition? What are pros and cons? Thank you.
