I'm running Ubuntu 12.04 on a Lenovo IdeaPad Z580 and have been using the default Backup application with an external SATAIII hard drive. However, when I connected it via USB today, it didn't show up in the file browser like usual, and the Backup application doesn't recognize that it's connected.
I remember bumping the HDD a little harshly the night before, so I'm hoping I didn't do something totally evil to it. Maybe it's not recoverable, but if it's not I'd like to know. I'm in the midst of writing a thesis, and backing that up via the internet is a bit annoying...
I like to think of myself as at least competent with these sorts of things, but after browsing other forum posts and solutions, nothing has worked so far to get things running as usual.
Some of this may be useful:

All of the above commands were run while the HDD was on, connected to power, and connected to my laptop via USB.
I wish I could remember how I originally formatted the HDD, but it was at least a year ago and I didn't write down what I did...
With my limited knowledge about mounting, to me it looks like it is mounting fine, but maybe not in the right place? /boot/efi seems like a weird place to me...
EDIT: Sorry guys, I wasn't paying attention at all to the storage space listings... Whatever I had been thinking about mounting at /boot/efi and about /dev/sda was wrong because the available space never matched what I should have expected (320G). I've concluded that the hard drive was actually fried, as suggested, and have since gotten a replacement.
