I have 3 HP servers running Windows 2003 R2 that I need to re-size the C: and D: drives. All three servers are Raid-5 and all three are running SQL. Long story short, the system drive (C:) is way too small and the data drive (D:) is way too big. I'm seeing several "Partition Magic" partition tools available. Any recommendations on which one to use. I could spend $150 or so to buy one.
