Except it wasn't an early design. OK, it was an early-ish wincheaster,
but stepper motor controllers are much the same whatever you sue them
for. The problems were known about and could have been avoided.

I believe it was the first HDD of any sort to use a floppy disk type of
interface. It was followed by the SA1000 interface, which in turn became
the ubiquitous industry standard ST506 interface. Since it was first, it is
not surprising that it had problems, many of which it inherited from the
Shugart floppy interfaces it was trying to resemble so as to reduce design
in times.

For pure
bad deisgn, nothing beats the Shugart SA4000 hard disk.
I have one of those. It has all the warts of an early design.
