Hi,

A lot of my 800k floppy disks, old or new, have the habit of being illegible on my SEs. 'Erase disk' from the Special menu rarely helped. Sometimes they'll ask "The disk 'disk name here' needs minor repairs. Would you like to repair the disk?" and clicking Yes doesn't cure it, and it just ejects the disk.

Here's the thread.

But I think I've found a cure to this 800k floppy disease!! Believe it or not...it's Disk First Aid. Works every time so far.
