Upgrade HP Mediasmart server OS Hard Drive?

[TheSiege]

Basically I want to do a clean install of the OS, and upgrade the HDD

The partition for the OS is 20gigs and the other 465 is alocated to drive extender. Any ideas how to do this?

I can't really access the 465 gigs. It all comes up as 1 drive along with my other 3 HDDs????

You have to first format the pc and then try to partition the drives..........
And then Finally upgrade the hdd.
