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?
