One day I decided to fool around with memory managers (out of boredom). I managed to fubar the MBR or something similar. Free trip to the computer shop, 200$ for restore and backup tape drive (the shop owner made himself a nice sell on a HP Colorado T1000 [still working]).

Similarly I once blew away the partition table and had to manually reconstruct it with the only available tool, MSDOS debug.com and a copy of Peter Norton's book.
