I have a 120 Gig with a ton of music and some video that all of a sudden won't mount! The dialogue box says it contains no volumes that OS X can read... (I'm running X.2.6 on a dual 1.4 MDD) Then both my iPod and any CDs wouldn't show up on the desktop or iTunes. Disk images couldn't mount because they contained no readable information. All of a sudden these problems vanished but my 120 still won't show up. I have to finish editing a project with that drive - any suggestions? Thanks!
