Hmmmm, I've been contemplating btrfs on some new installs
with the eventual goal of a CEPH network file system, on top
of ext4 and/or btrfs. Is this issue just with the drivers, or 
related to btrfs too? 

How is btrfs , from the "driver's seat"?

Does this aberration you detail, extend to the Green Seagate 2T drives?

> I just saw on the mythtv list about the sector size problem these drives

Can you give a precise link to this list or can I follow it (read only)
via net news?  (if so what is the news group name)?

I'd like to read up on this issue, as I have several gentoo installs 
(very soon) that will have  RAID1 using (2) ST 2T green drives.

Alternative RAID configs and performance/reliability results is
also of keen interest to many; so thanks for posting about these
issues.


James
