That doesn't work.  You can't erase a modern hard drive that way.  It used
to work on the old ones, but now even powerful degausers can't get through
all the platters -- the outside platters shield the inner ones from the
magnetic field.  Note that the degaussers for sale at Radio Shack can barely
erase a floppy disk.  I put some floppies I thought I had erased into a Mac,
and after working for a few minutes, the mac offered to repair the disk...
Another floppy was able to crash Win 98 repeatedly, but that's another
