Not really just today, but overnight, I finished transferring all my ripped music to my newest hard drives. The 750GB I got at a super deal a couple of weeks ago, the two 320GB drives I bought in the falll and one more 160GB which I have had for a while, are full of nothing but music. Back-ups are spread across a huge number of 40, 60, 80, and 120GB drives, though.
Of course, I also have my original CDs, reel to reel tapes, LPs and library card (SHSHSH!) in case of major failure.
Much easier to access four drives than what seemed like "forty four."
