Thanks for the reply,
I don't know if I've read this correctly or not, but it appears that that the 1st and 2nd smart error happened at the same time "29801 hours" on the same block "3894526032"
The third error happened some time later at at "48162 hours" on block "3166961520"
So from what I understand there has been "18361 hours" or 765 days just over 2 years since the second and third errors.
I'm assuming I can put move any critical data onto the other drives in my array and leave this drive just for media content that can be easily retrieved again if the drive ever decides to totally fail.
I currently have a 4 drives, with one used for parity
In regards to linux and ssh experience, I'm confident I'll manage.
Can you see any problem with this thought pattern?
