So I have a 250gb WD external USB drive with a ton of stuff backed up on it. Long story short it was working the other day, but now its not mounting. I used DiskWarrior and it repaired permissions and such. It also says "This disk does appear on the desktop" and yet its not there. Also, in Disk Utility, I unmounted, mounted, ejetcted, etc and nothing makes the drive show up. It tells me how much free space it is and its the right amount so I know the drive isnt erased. Anyone know what I should do?
