So it turns out that my hard drive had a mechanical failure and nothing was able to be retrieved.
Isn't that fun?
There are companies that can work with the failed hard drive, but they are not cheap. It will be a while before I find out if anything on the old hard drive can be saved. So for now we're starting new.
Isn't THAT fun?
But Thanksgiving WAS fun, so that's good. And I hadn't deleted all the pictures off my camera before the hard drive crashed, so I've got a few weeks worth, anyway.
