Suddenly everything goes awry without any sign of what you did wrong. It is as if someone just came in and blew up your computer, leaving you with little or nothing of what you had.  Why does this happen to us innocent college students, just trying to make the grade? Why does it have to happen at all? As you can see from this user, it was like a grenade went off inside her computer, blowing away all her information:

“I had typed seven pages of my ten page term paper, and BAM! I lost the whole document”
