More early 8" floppies: hard sectored, IBM Minnow, Intel Intellec and IBM Demi floppies

We complete our early floppy diskette education by taking a look at a hard sectored 8" floppy, an IBM Minnow floppy, an IBM Demi Floppy, and some oddly formatted Intel Intellec diskettes. Will we be able to recover the data?
