I went so far as to install Windows 7 on the 840 Pro, downloaded and ran Samsung's own tool to verify it was at the latest firmware and was healthy. The smartctl is below.

update-smart-drivedb
smartctl -t long /dev/sda
<wait 20 minutes if system is idle; longer if active>
smartctl -x /dev/sda

Report that smartctl along with dmesg.



[root@localhost digimer]# smartctl -a /dev/sda

Weird. 15 hours for an SSD offline data collection? On my 830 this figure is 1020 seconds, same as the extended self-test.

The output of the smartctl commands are below. Pardon the ignorance, but what's "offline data collection"?

ps - thanks for the help. :)
