At least the 5 1/4 disks did. 3 1/2 disks did not like it at all. As long as you didn't crease anything the 5 1/4s would usually still work. The data wasn't especially dense on those (if you could see magnetic fields the patches would have been large enough to be visible to the naked eye) so the could take some abuse. At least until the magnetic coating started flaking off.
