That's not actually true. There are specific byte combinations that trigger certain things when dealing with MFM data and flux level data. Paula is by far more carefree than the WD177x series, but you still can't use every byte (0x00-0xFF) in the MFM data. I know a little bit about Paula and floppy drives... I created Supercard Ami, Supercard Ami II, SYBIL, and AMIA hardware devices for the Amiga to copy/image floppy disks. I make a product right now that also images/copies floppys:

Besides giving you the ability to backup your software, this product creates flux-level images that can be used under WinUAE, FS-UAE, E-UAE, and FPGA Arcade Replay to give you an exact emulation of a real disk, just as real hardware (Paula) sees it.
