Hi,
Four weeks ago I bought a new 2TB Seagate Barracuda internal SATA
drive. That drive has two 667GB ext4 partions (667GB unused) and it is
used for storage. My main system (Debian Sid 64-bit and KDE) resides
on a 40GB SSD, also using ext4.
Two weeks ago I noticed a severe performance drop, where any file
manager couldn't view directories on the 2TB disk without a one or two
minute penalty. After that I have had three hard freezes of that disk
and the entire system. Before the freeze there is very much hd
activity and finally I need to turn the power off. I have now also
made a backup of /dev/sdb1 should it be fatally serious.
I was recommended by someone at the #debian irc to make changes to the
spindown_time but that only helped for a few days. Yesterday, the 3rd
freeze came and the system wouldn't even recognize the disk after
reboot; just 'clicking' waiting for a response. I showed the kern.log
to someone at the same channel who concluded that this should be a
firmware issue.
Here is the latest kern.log which may identify the issue: I hope it
contains the relevant details. But first the output of smartctl -a
/dev/sdb.
I have now set the hdparm spindown_time to 0, disabling disk sleep
which seems to have been the culprit as judged on messages in the
Dolphin file manager etc.
Thanks for any help!

The SMART data shows there haven't been many start/stops other than from
power cycles, so I don't think spindown is related here. The error log
entries and the Offline_Uncorrectable and Reported_Uncorrect attributes
would indicate that your drive is having read errors. Think you likely
need a new drive.
