I've somehow lost access to all my non-linux drives. I'm not sure how. I have two other hard drives set up (a windows boot and an external usb I was using under windowsxp). A few days ago I could access both under linux with no problem. Now, I see them listed under media, but when I click on them, nothing is there (same thing happens when I go there in a term window). Now, the computer (under linux) sees them, but I can't see anything in them. (in nautilus it shows "(Empty)")

Any ideas what happened or how to get access to them again?

My guesses as to what might have caused it: -I was trying to set up AdobeAIR (unsuccessfully) and had to make and remove a couple of symbolic links. Never got that to work but maybe links I made or removed did something?

-I was also trying to set up nautilus so that I could enter it with sudo permission. I also didn't figure out how to do that successfully, but maybe something I did while trying messed it up? (I think I installed and uninstalled nautilus-actions configuration tool).

Note: I'm working on a relatively new install of 12.04
