Take a spare floppy and format it then write some file to it. Now can your computer read it?
My 3.5 floppies that I have a great deal of information on will not work on 5 different computers. Three have 3.5 drives and two have external drives. I have a format error and have been told by "experts" that my disks have deteriorated. but they still work in my older camera. MS Works and Word Document files will not work at all. I am using a Gateway GT5408 and my lap top is a Sony Vaio all use either XP or Vista. The other is a Dell and two off brands. I don't believe my disks are at fault. I think it is a Windows fault. How can I recover the data from around 50 3.5 disks?
