Welcome,
I experience continuus degradation of btrfs system partition on hybrid
750GB Seagate Momentus XT-2 (ATA ST750LX003-1AC15, rev. SM12). dmesg
fills with hundreds of errors like "btrfs csum failed ino 93608 off
425984 csum 2316250426 private 3579463503".
I had simmilar problems with the older model, Seagate Momentus XT bought
two years ago, where firmware update didn't solve them (cf.
http://superuser.com/questions/313447/seagate-momentus-xt-corrupting-files-linux-and-mac
and
http://forums.seagate.com/t5/Momentus-XT-Momentus-Momentus/Momentus-XT-corrupting-large-files-Linux/m-p/109008).
Now I want to give Linux another try on this amazingly fast hardrive.
Yes - the drive perfectly well under default drivers on Windows XP. I
use it everyday and I never lost a single byte under Windows.
What can I do on my part to help you troubleshoot the problem? I guess I
might do some sort of tripwiring files to see that their contents
actually degrades, but I think it the result is obvious and not very
helpful to you.
If you can't help me, please advise me, how to heal the partition - the
offline btrfsck (from btrfs-tools 0.19 available on Mint 13) doesn't fix
anything here.
Is there any way to tell which files are getting broken?
I use Mint 13, 3.2.0-30-generic 64-bit kernel.
