Hi!
As I'm interrested when my disks will die I wrote this plugin
(It's far from complete and was just my first test)
Do you think this is useful?
Is there a place for python plugins where I/you can add this?
Did I miss that there already is a plugin to read
https://en.wikipedia.org/wiki/S.M.A.R.T. status?
btw. nice work guys!
Regards
Florian
