Probably. They do say they may be able to decrypt the drive if I haven't ruined it sufficiently, which may give me a chance to get all of my files off of it. Ideally, once they do that, I'll put the spare 1TB drive into the machine (we bought it when we though we could do drive cloning, which we cannot do because of the encryption), they'll re-image to that drive, and I can pull all of my documents off of the cannot-boot older drive. That would be helpful. In any event, I once again have to start picking my way through the process of rebuilding a computer and getting comfortable with it.

I do back up a lot of stuff, but it doesn't seem possible to back up everything, which was why cloning the drive periodically (I could set it to run overnight) was so useful.
