You're dividing a 40GB hard drive into 5 partitions? Ouch! I have a 30GB hard drive for Poser 4 alone, and it's almost full. I'm having troubles using Poser. You really should continue getting one hard drive exclusively for Poser. Then take that 40GB hard drive, and make one partition for the whole drive. If you're working with graphics, you need more room, not less. You lose lots of efficiency when you divide a "small" hard drive into so many partitions.
