I get a 6x blinking LED when powering on. I have already tried some stuff according to the FAQ (using Win Vista), but the force update procedure does not succeed. So I first wanted to backup data before actually changing data on the drive.
So I removed the drive from the NAS housing and connected it through an USB adapter to an Ubuntu PC.
It instantly recognizes and moutn /dev/sdb2 as 5.3 GB filesystem, but the interesting partition is not mounted automatically.
I tried a manual mount:
sudo mount -t xfs /dev/sdb6 /home/andreas/big2
This is how the latest dmesg entries look like:

So why does the mount command fail giving back a

[ 1524.113218] XFS (sdb6): SB validate failed
?
What is wrong here? Thanks for helping, Andreas.
