 Why not just put a piece of scotch tape over the notch on the disk, as
 you might do to write-enable a standard audio cassette that has it's
 write enable notch broken out?

 The problem seems to be the fact that the se/30 checks the disk type, then
 tries to read MFM on the FDHD, fails, and asks to format the disk.

 Perhaps if you fool the hardware the computer can successfully read the
 disk...
