I have (2) WD caviar black 650 GB hard drives run in a R.A.I.D. and I also have a western digital caviar blue p.o.s. 150 GB or something. If I used the WD blue with a seperate operating system to download songs/videos, is it possible for any viruses it gets to move to the R.A.I.D.. The alternative is building another computer strictly for downloads. plz help.
