No ID address mark was found on the floppy disk"...

Here I was, going through some old floppy disks when suddenly this happened.
After inserting one and trying to open it, I got the following message: "A:\ is not accessible. No ID address mark was found on the floppy disk".
Now this happens with every darned floppy I try...
I will be very grateful if anybody could help an old techno-dunce with this.
By the way, I have Windows XP.

I know this as well, but the thing is, that for some reason right now I can't open any floppy.
