Hi,
Right before Commodore was going to declare bankruptcy we were selling the LC'040 based machines and some of those shipped with DD floppies rather than HD ones. Perhaps they could no longer order them - bad credit?
Again, just my 2 cents (Canadian)...

P.S. One other thing - when you prop up the dust door on the drive, do you see white plastic sensors for the Read/write on the left and the HD sensor on the right?
