New to Zip drives....have a question

[SilverThief]

Ive got an internal Iomega Zip100. I have a couple of disks that have stuff on them, one is completely full. When I try to erase the disk, it says I cant because the disk is write protected.
Does this mean I have a useless disk? I dont need or want anything on it.
Or is there some way to delete/format this disk?

If you installed the zip tools then right click on the drive in explorer and go to properties. There should be a tab with Iomega on it. Click on that and you should see the drive protection status towards the bottom and a button to change the write protect status.
