problem with my new hard drive!!

I have a problem with my 160GB hard drive to buy in mpcstuff, when I want to save a project I can not save the samples (file write error) only save the data, I formatted it from my macbook and then live from the mpc and nothing, also 2xl jjos reinstalled and nothing, I hope very much for your help, wait for my hard drive to south america chile, Greetings

you have to format the hardd drive with the MPC operating system not your computer. It is in the manual and it will show you how
