Yes - it works only on 3.5". The differences between 5.25" DD and HD
disks are so big that when you format a 360kb disk to 1.2mb disk,
you'll get at least 500kb of bad sectors. The rest of that disk is
also very untrustworthy, since the media is really different. But
converting 3.5" DD to HD is usually quite safe.
