Hi, I installed a second hhdrive on my brothers pc. We deleted iTunes from his C drive. Then I installed iTunes on the new drive. Now he says when he downloads music the music is not only installed on the new drive but his C drive also (and iTunes shows up on the C drive again). When the bios run, the C drive is the master and the new drive is the slave. Btw these are IDE drives. Did I forget to do something when I installed the new hhd? Help please.
