OK, ready to

?
I had this old Intel Pentium 33 (or was it 66?) MHz compy given to me. Big step up from my 8MHz 286. It had Windows '95 Plus! on it, 8MB RAM, and a 200 MB Hard Disk with DriveSpace 3 compression enabled. Oh, and the dude who gave it to me had messed it up somehow. Not knowing quite as much back then, I messed around with it a bit before deciding to re-format.
For some reason or another, I couldn't / didn't want to format it in my computer, I had to take the hard disk and put it in my Dad's computer first. (Probably to back-up something & restore it after the format, or to transfer the system files - I could have used a floppy, but, like I said, I was a newbie back then, just learning DOS commands & Windows Control Panel settings.)
Anyways, so I pop the hard disk into my dad's compy - I didn't bother asking him, as he seems to decline to endorse any plans that he doesn't understand, and doesn't think is worth his figuring out... I know he could understand it if he wanted to, but he figures he doesn't have time, and he can always hire someone to fix his compy (now he's got me for free

), so why bother... which becomes a catch 22. I usually settle on "asking forgiveness is easier than asking permission".
You folks probably see trouble brewing already. Yup, I boot to the DOS prompt, type in
format c: /q
hit enter, y, enter, enter, y, enter, until it starts ... just as it says "formatting", I realize...
On my system, being the only hard disk, my HD was c:... since I had hooked it up on my Dad's system as slave, it was d:... my dad's hard disk was c:
I realized this in about .01ms after seeing "Formatting Drive C:" and I hit Ctrl + C, Ctrl + Break, Esc etc etc many times, all to no avail... it quick-formatted 1GB (mostly full) in about 2 seconds.
Luckily for me, I had backed up my Dad's documents about a week or two before, doing another unauthorized experiment... so my Dad wasn't too awefully mad when I told him I could get his stuff back. But it took almost all of a day's work to get his system running back the way he had it again.
The worst part is, I learned about the unformat command not too awefully long after that...
