i´ve flashed hundreds of drives with my via6421 controller.
Just dont install drivers, only install PortIO
Works fine with EVERY drive.
Perhaps there are other solutions. But there are so many onboard controller out there...
Off course you should install the neweste drivers for all your PC-Components.
But if everything fails, buy this controller-card for about 20$ and you should be fine.
