[Disk read errors on 3 months old disk]

Thank your very much, seems very likely that's exactly my problem.

Will update this post after rebuilding the disk.

[Disk read errors on 3 months old disk]

Using 6.9.2

 

I bought a data disk about 3 months ago and added it to the array.

Within the first 2 weeks I got a single read error. I checked some forum search results but didn't really get too much out of it.

I decided to format the disk, change the SATA-connector (using a HBA, used another SATA out from the same reverse breakout cable) and rebuilt the disk.

Afterwards the array turned good.

Everything stayed fine for a couple of weeks.

Recently the same disk failed the daily health check and showed 35 read errors.

I ran an extended SMART check, but nothing suspicious. At least what I can make from it, according to google research.

I was kinda busy the last couple of weeks but today I noticed the read errors jumped to 51.

 

Is the disk failing?

 

The concerned disk is disk9/sdi.

 

Anything I could to try fix the disk or should I send it in?
