Date: Mon, 02 Aug 2004 17:36:34 -0400 Back in the days when the 20 megabyte drive was king, I used to do that all the time. I moonlighted at a local computer junkyard. We mixed and matched parts to make functional hard drives. Sometimes the'd not have all the capacity of the original drive because a board that looked about the same but wasn't was fitted but they worked. I had a little homemade clean box I used to open the drive compartment. Consisted of a table top sand blast cabinet, a HEPA filter element and a muffin fan to blow the air through the HEPA element. The procedure was fairly simple. Remove the electronics card and blow off all the dust with an air hose while holding a thumb over the vent hole. This part is very important. Then put the drive along with the needed tools in the box, turn on the fan and get a cup of coffee while the air cleans up. Come back, open the drive up and do the needed work. I've swapped head assemblies, installed new bearings, even removed defective platters from the stack and replaced them with platters taken from other, defective drives. Back then at least, if the platters were the same color and finish, they'd probably interchange. I operated one of the very first commercial ISPs back then, dixie.com. The unix host machine (33 mhz 386 with 12mb RAM) sat in my office's lobby in a 19" rack. I'd taken a 20mb drive, removed the cover, made a plexiglass cover to replace it and mounted it to the front of the shelves. I had it connected to the machine as a /tmp drive. No big deal if it failed but it never did. I arranged a light to shine on the drive to make it very visible. Amazing how much time people would spend staring at that drive, especially when the system was batching news to go out. I guess I'm not surprised that a modern drive would survive an opening if the air is fairly clean. I know that modern drives have built-in clean-up filters so any contamination should be filtered if it doesn't hit a head first.
