Hmm,
He states "i am useing a floppy cable with a twist in
it and a 20 pin data cable."
hard drives did not use a twisted cable on them.

No IBM included a twist in their 34 pin hard drive cables, it was different
than the floppy twist.
Most clone manufacturers didn't bother with the hard drive cable twist.
On the hard drive cable the twist merely changed the drive select signals,
on the floppy drive cable both the drive select and motor on gets twisted.
The floppy drive cable must be twisted to have drive A work properly the
hard drive can work with or without a twist.

IBM DID use a twisted cable for hard drives!
It was not the same twist as the floppy cable.
If IBM hadn't used a twisted cable, (or a cable with missing pins ala RS)
then they would have had to teach their people about drive select jumpers!

The IBM 34 pin WAS twisted. It was not the same twist as the floppy
cable.
