That defies > all logic on the principals of how a hard drive works. Do you even know how a hard drive works ? Have you ever opened an IDE drive and looked inside it ? Most if not all of the IDE hard drives have a magnet in it that is about 1/2 inch wide and an inch or so long and maybe 1/8 of an inch thick. It is very strong. Without that magent the read/write head would not move. Look here especially near the end to see the magnet. http://www.youtube.com/watch?v=wEfA3FB-m6U&feature=related

From: js.b1 on 6 Jun 2010 12:33 Buy some large 100mm PP castors, plank of wood, screw a Really Useful Box of 9L (short narrow oblong) 18W (large fat oblong) 19L (tall narrow oblong), attach a vertical pole for manoeuvring, done. You may want braked castors if on a slope. You can buy something similar, with drawers, but the weight can become a pain unless you have a sloped door threshold.

Any idea what that shield is made of? it looks like aluminium, but isn't. |
