While you had good luck with that, the storage of the disks may have had an impact on things.
More importantly is the FACT, that the heads on a floppy drive can get out alignment easily. I have on more than one occasion in the past, made a floppy disk and immediately attempted to use it in a different Windows computer without success. Moving the floppy back to the original computer allowed that computer to read the disk.
That is why I stated for best results use the same drive the disks were originally created on. Of course, if that drive is no longer available then you do what you gotta do.
I have disks even older than 15 years that still work. I is still a crap shoot. Floppy disks are the least reliable media you can use for long term storage.
