K Becca, hold the floppy, with the round metal piece facing you. If you look in the upper left hand corner of the floppy, you'll see a little tab. It needs to be in the down position to where you can't see light through it. That will unprotect it.
To format (in Windows) Go to your Windows Explorer and right click on the "A" drive (where "A" is the drive letter for your 3-1/2" floppy") and select "Format" Select what you want to do ( I would suggest "Full" format) and click go or start or whatever! LOL
And then you're set!
