Yesterday when I worked on my MBP, I saw my external hard drives. And, this morning, I did a software update and after the update, I don't see any of the hard drives anymore. I didn't see what the updates were; I just accepted them and went away. After the restart they aren't there anymore. By the way, when I remove the USB cable to the drives, Lion complains. However, none of the applications that access the drives can see them. I am on Lion, 10.7.2, now. Things I've done to try to remedy this: Removed the USB from the mac and plugged back in. Restarted mac. Anybody know what the heck is going on? Thanks.
