It's strange. I have 3 out of 4 drives in a box here reporting FUA
capability, and I have now tested all three of them both with plain FUA
writes and NCQ FUA tagged writes. I used data integrity verifying
writes, and the data is sound as well. fs likewise, I used ext3 mounted
with barriers enabled.
What exact model drive is this? It could also be a raid funny. Tejuns
proposal with testing the drive alone with ext3+barriers is a good one.
