Not quite the same but had a PC engineer kill a 486 SCO Unix server whilst trying to fix the external DAT backup drive.
I was on holiday, I told them not to touch it until I got back but they thought they knew better ("they" in this case being the parent company) so called in their tame maintenance company who'd clearly never worked on a Unix box before. Engineer waltzes in, decides he needs to shut the server down but doesn't have a clue how so just turns it off.
It took me about a week to get it fully back up and running with a mix of file recovery and restores from the last successful backup.
The parent company wondered why I declined to go and work for them.
