You CAN'T use the media test on a floppy you want to keep!!! It wipes the contents of the disk!
If the media test says its bad, then its bad. The test writes an 8us pulse width and then reads it back to determine how much noise there is. The allowable amount of noise is much more than a standard floppy would allow, so if it shows up as failed then the disk can not be used. If you can't format it with MS-DOS, that would also tell you the disk is bad.
3.5" disks did not fair well with time. These commonly fail, where as 5.25" disks left in the heat and warped seem to always work fine.
