Can I make a PIO hard drive run in DMA mode?

Threaded View
Is there any way to make an old (1994 era) Conner CFS420A hard drive
work with a USB to SATA/IDE adapter?

When I hook up the CFS420A to the adapter it spins up OK and is
recognised by name in the Device Manager (running Vista Home Premium)
but is not given a drive letter.  From what I've read online it seems
the problem is that the old HDD is in PIO mode and therefore isn't
"seen" by the adapter I'm trying to use.

I want to be able to access files on the CFS420A using my laptop, but
it seems impossible unless I can get the drive to go to DMA mode, if
that's even possible.

Any ideas?  Helpful ideas!

not a DMA/PIO issue

you need to go into disk management and assign it a drive letter
