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).

Have you been able to switch the data cable for a know good cable? That 
solved the problem for me.
