This is my first posting here so I apologize for any improper use.
I have a bunch of old floppies and I was formatting them so I could sell them on Craig's List. Most format OK (full format) but some give the message in the title above. All of the disks have the write enable switch in the correct position. I am using Windows XP SP2. I've completed about 60 with 9 of these failures. I would appreciate any suggestions.
