FreeBSD will drop down to PIO mode, probably mode 4.
According to Scott Mueller's book, PIO mode 4 offers up to 16.67 MB/sec, whereas UDMA can offer up to 100 or 133 MB/sec. So, yes, less efficient (but also a bit quieter in my experience).
And the cpu load should increase, no ?
Have you been able to switch the data cable for a know good cable? That solved the problem for me.
I've tried a brand new one, but no difference...
