Array has errors (64) - do I disregard?

Hello,

 

Last night I recieved an email that my server encounter some errors on a disk. This concerned me greatly because just recently (2~ weeks ago) I went through a whole ordeal with a drive seemingly failing, and then the replacement drive I bought failed, so had to buy a 2nd replacement drive to fix. (Context here)

 

Immediately upon seeing this error I began a SMART extended self test on the drive, and it has just completed. It returned without error. I'm attaching the diagnostics to this post.

 

Do I simply disregard this small error of 64 as a one off random thing maybe caused by a memory failure etc, or is this something I should take more seriously? I have had my unRAID server running great for 3 years, up until a couple of weeks ago. The previous incident clearly seemed that the drive itself had failed (under warranty) but now with these errors coming up randomly on a different drive, perhaps something else is also happening that needs to be addressed? I can't really recall ever having errors on drives before outside of a failed drive and faulty SATA cable.

 

What are the next steps I should take? Thanks.

It's not logged as a disk problem and SMART looks fine, so most likely a power/connection problem, could also be spin down related.

Given you are running into problems frequently, might be good to revisit your cables / connections etc. Both power and data. That is probably the only common thing here

Okay thanks for the suggestions.

 

I will turn the server off tomorrow and check what cable it's on. (Mobo / SAS card)

 

I thought I was being smart last time with putting labels on all my drives. Now I realise I'm an idiot for not labelling which end of the system they go to.

 

Edit: Can see in devices which drives are on LSI card / Motherboard ports.
