A little over 40 years ago, while we were still using TRS80's at the college, the purchasing agent was sleeping with a vendor, and got us RoyType HD diskettes, instead of what we asked for (Verbatim Datalife). When used in the TRS80s, it would format and write without showing errors, but

DD 5.25" disks are about 300 Oersted. HD 5.25" disks are about 600 Oersted. If you use HD disks to write DD content, the data fades away real fast. However, on 3.5" disks, the difference is more like 600 Oersted VS 750 Oersted, and you may get away with using the wrong disk. 360K disks are
