My external 1T drive produced an error on my Windows Vista and stopped being accessible. Other computers could access it for a while and then it wasn't accessible to anyone. It wouldn't mount on Gentoo, and it won't mount on my Mint desktop although it does show up as a drive, it just won't mount.
So I searched the forums and found a post about a similar situation, and the first piece of instruction was the following code and to post the output.
sudo lshw -C disk
