I have a Premiere. I upgraded the hard drive right after I bought it. The instructions I followed suggested that I keep the original hard drive. I think it was Ross Walker's website. I went back to read it, and maybe I'm blind, but I can't see why he suggested keeping the old hard drive. (The old drive is a Western Digital WD3200AVVS). The reason I'm asking is that a friend of mine asked me to fix his Series 3. It's stuck on the 'Welcome... Powering Up!' screen. My question is: should I just buy a new hard drive or use the "old" one that is basically brand new? Is there a compelling reason for me to keep the old one?
