FWIW I have just had (different) issues with the Samsung F1 drives.

The Silicon Image Sil3112 cards I use would see them but then hung the machine.

I managed to buy another Sil card with a flashable onboard BIOS and a freedos flash upgrade fixed my issues.

Elsewhere on the web I found that people needed to use the samsung utility to downgrade the drives to 150Mbs (the jumpers don't always seem to do the trick) - I didn't investigate the sw.

I bought 4 2-way Sil 3132 PCI-e drivers ($16 each from china) and am currently installing 5 of these beasts in my Myth/video/media box.
(should keep Mrs lbt happy for a while)
