Sometimes another drive will read a marginal disk. Remember, their media is made of microscopic magnets. Magnets are vulnerable to any nearby electric field and also tend to lose strength over time. I have even dropped a good disk and had it no longer read...can't figure that one. Some disks lose their ability to be formatted as well. Usually you will get a message saying track 0 is bad. It's time to toss it.

I have a box of 3 1/2 floppies kept together in plastic box.
Yesterday a particular floppy worked, today I get message "DISK NOT FORMATTED".
Just curious, why disk would lose (?) info. All other disks in box are OK.
Is there any practical way to recover/save the info that was on the disk?
