Hmm, I can't say for sure. This server is a backup location in a home in Germany. It is connected to mains power, so I don't have monitoring of power spikes or similar.

See here (I have added both `smartctl -a` and `smartctl --xall` to this gist): https://gist.github.com/nh2/db886f3afbbb4b186aa5088ca2782c06#file-smartcl-output-txt-L63 https://gist.github.com/nh2/db886f3afbbb4b186aa5088ca2782c06#file-smartcl-output-txt-L158 > There are assembly bugs floating around in that general span of > versions, so an upgrade is a good idea.
