High density disks on double density drives

In PC's, I always use 1.44 meg disks in 720k drives. I just tape over the
second hole, and format them in one of my 720k machines. I have one of
these "doctored" disks that is 5 years old, and still holding its original
data strong and true. It has even been around magnetic fields (slit off
monitor onto back, right above coil), and hasn't lost a byte.
