In that case, I'd carefully scan the kernel log (sometimes it is not 
enabled, or it goes mixed in /var/log/messages), watching for DMA related 
messages. If the kernel sees a dma timeout or some other problem when 
using it, it dissables dma on that drive and continues.

What exact command do you use to set it? I use simply "hdparm -d1 device", 
and let the drive choose the exact mode.
