My heart sank at the very thought.
Sometimes an adrenaline rush can be good - at other times you just want to crawl into a corner and cry.
Computers are like childen you need to give them 100% of your time and attention or wave goodbye to a nights/weeks/months/years work at the press of a button.
These 'ARE YOU SURE' reminders may be a pain but I'm glad they are there.
I'm glad you were able to recover so much. Bet your back-up has a back-up now!
