Adobe Media Server: Connecting Hard Drives

[WCKicksAss]

Hello,

I'm running into bit of an issue. I've got 3x1TB HDD's on my Server, but I got Adobe Media Server connected to the largest HDD for low space. Like 100gb left. My host says it's not possible to make the hard drives 1x3tb. So does anyone know how to connect this? Reason: Video on Demand. Will tip via PayPal if you can help


Thanks​
