The HP agent recommended uninstalling the device driver (in Device Manager), rebooting and letting detection reinstall it. This action seemed to fail as it presented the following error message follows:

I click Finish, ignoring the error and suffer no other problems. But I would certainly like to find out what is going on here, before the drive goes West again. I suspect corruption in the registry, but where to start is a bit of a mystery. HP's suggestion was to wipe the drive and reinstall the operating system, and all my applications - not very palatable for so little payoff. If anyone can offer suggestions, I would be humbly grateful.
