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?
You'll need to provide some more details such as how old your FreeBSD
8 is, drive model number, controller details and the actual error
message you are getting.
I recently bought a Hitachi Deskstar 7K2000, which is sitting in an
Astone enclosure (identifying as "Sunplus Technology Co.,Ltd.").
Unfortunately, I'm limited to USB2 whilst I wait for the correct eSATA
adapter. Whilst the first disk was DOA, its replacement is running
perfectly (though slowly) with my 2-week-old FreeBSD 8.1-stable. In
particular, one of the first tests I did was to write a pseudo-random
sequence over the entire surface and then verify it to ensure that all
sectors are uniquely addressable
When I booted FreeBSD on the bare metal, the problem was not present.
Nor was it present when I attached the drive via USB to NetBSD and that
got me to thinking because it did show up with NetBSD under VMWare...
thus...
This turned out to be a VMWare issue.
The problem was solved by upgrading VMWare Workstation from 6.5.3 to 7.1.2.
Hope this helps.
