Question : 'Unable to mount expansion drive'

When I try to access my external (USB) hard drive on Ubuntu, I suddenly get the following error message:

  'Unable to mount expansion drive. Not authorized.'

However, I can access the drive fine on another machine. (It might also be worth mentioning that my audio output has suddenly stopped working too)

I googled the error message but couldn't find much, except one guy saying it's an unresolved bug for which the only solution is a reformat. But I thought I'd get a second opinion first...

Thanks!
