Sooner or later. this messages will be followed by something along the  
line of
ad6: WRITE_DMA failed

and you'll get READ_DMA failures as well.

As others have suggested, do not trust this drive.
You may command
	atacontrol mode ad6 pio
or put
	hw.ata.ata_dma=0
in loader.conf.

The errors will disappear. Use this if you can't backup because the reads  
fail.
Worked for me. YMMV.

Even if smart does not find anything -- use the drive for junk purposes at  
max.
