very weird overload cache disc problem

Hello,

I’m using Cubase elements 7 since a few weeks, and i have got a big problem with my differents hard drives.

Here is a video of my problem: http://www.dailymotion.com/video/x2rgbz5

Only my ssd is working, i have to put my projects on it or i want to put them on my barracuda hard drive. When i put my projects on the barracuda or another hard drive, i have got white noises and overload cache disc problems with only 2 tracks, sometimes one! On my ssd, 20 tracks and VST: no problem!!!

Cubase is installed on my ssd, i’m using windows 8.1, intel i7 4790, 16go ddr3 ram.
