You see, many (about 4) years ago we purchased a 2nd hard drive from Best Buy, and for some reason we had them install it. Naturally, they put in the standard-slot area. The hard drive was too small to fit by itself, so they put these two metal extending bars on either side. The problem is, these bars apparently made the contraption too big to fit into a standard slot, so whoever was doing the install decided to wedge it in diagonally between both slots, to the point where the metal braces actually bent around it. Because the drive was now misaligned along every axis of the compartment, the installer only managed to put in two screws to secure it, instead of the expected eight. What's more, the two screws were on the same side of the drive, leaving the other side to hang freely.
This is how the computer stayed for several years until that fateful day when I needed one of those two slots blocked by the metal monstrosity. Being the determined fellow that I am, I decided to try to yank out the Best Buy hard drive to try to clear out some room for the new CD drive, and then put it back in somewhere else. Not surprisingly, the thing came out quite easily, given that it was only loosely held in by two screws. Now here's the shocker: I decided to un-bend the metal brace and try to put the hard drive back in the right way. It fit perfectly. All this time I had been silently respecting those Best Buy install "technicians" for not being discouraged by a hard drive that didn't fit, and using their ingenuity to install it anyways. Now, I realized that drunken monkeys would likely have done a better job. That’s all I can say. I hope my attitude towards Best Buy has now been justified.
