As another body that today bought a 2TB HDD, I can confirm the presence
of kernel messages relating to READ_DMA48 with FreeBSD 8.
The drive in question is a Hitachi one, not a Samsung.

Is it the drive, system or operating system?

Well, the drive works without any such error with both Windows 7 and 
NetBSD 5.1.

So it looks like the finger is now pointing as a bug in FreeBSD... and 
if it is fixed in HEAD then it needs to be merged into the branch for 8.1.
