SOLVED: [6.6.6] Third drive failed in two weeks

So I've just had my third drive in a fortnight go bad.

Last week I took the precaution of adding a 2nd parity but had another go unmountable since then.  Now the drives failing have been old but I'm wondering if there is something going on here which I'm not noticing.  Posted diag from today and one from a v poory state last week.

 

Any advise / comments much appreciated..

[off to buy another couple of drives!]

thanks, I noticed disk18 and have a replacement now - preclearing.

While starting a pre-clear, disk2 just went offline!!

 

It does seem that all these drives were on the same cable.  Bi of rearrangement and that cable's out of play now.

 

REALLY glad I added two parity now!

 

Other than drive18 with errors, would I be right thinking that they're likely OK?

Are you sure you have enough power for all those disks? Maybe you have an old power supply?

I would be suspicious of the Power Supply.   There have been several hardware problems lately which appear to have been fixed when the PS was replaced.  (PS are a much more complicated device now then they were back in the early 2000's and, perhaps, there has been some manufacturing cost cutting going on...)
