Updated some files last night and was prompted to reboot. when I rebooted the computer I was greeted with a black screen and a message stating:

error: file not found grub rescue>

Did some research and got the grub2 loaded back up and working again. I can now log into my computer just fine now. Now the only problem is that my external hard drive is not showing up on the desktop when I plug it in.

Ran a disk utility and it shows up there.

Ran gparted and it shows up there. However, under the Mount Point column it's showing /boot/efi. Is that value supposed to be that?

Issued the command cat /proc/partitions: no error messages and the external shows up there.

Issued the command lssub: external hard drive shows up there.

For whatever reason the system isn't putting an icon on my desktop allowing me to mount and access the contents of my external hard drive.

Any thoughts or ideas? Thank you. I'm running Xubuntu 12.04 64-bit.

Update: Was using Thunar to find some files and I was able to access my external hard drive by going to /boot/efi/ and all my external's files are in there. I don't know what's going on.

It should not be mounted there. Did something get corrupted? from terminal run mount – oldfred Aug 22 '13 at 15:14
I honestly don't know. When I was having the issue with the grub rescue I loaded up the Xubuntu live CD so I could connect to the internet and search for a resolution. My research led me to install a program that fixes grub boot issues. Maybe when I was using that program something got corrupted/changed. – Jason Smith Aug 22 '13 at 18:36

Ok, unplugged the external and left it for days without doing anything to do. Plugged it in to see if I could salvage it and as soon as I plugged it in it was recognized by the system and it's icon appeared on the desktop. Seems to be working now so I'm not sure what was going on with it before.
