a zip disk question

[Gregory Nowak]

Hi allll,

As you hold a zip disk rright side up, and flang away from you, like you would insert it into the drive, in the front right corner on the underside of the disk there is a tab. Since this tab seems to be moveable, is this a write protect tab? If so, then how in the world do you engage it? If not, then is there a way to write protect one of theese disks? Thanks.
Greg
