Loose cable? (I hope)


Recommended Posts

Hey guys, I started having serious stuttering issues last night while watching a movie streaming from my unraid box.  I pulled up myMain and saw a bunch of errors (shown below).  After some wiki browsing I found a page saying these errors usually indicated a loose cable but I wanted to be sure as this is my first issue with my unraid system ever.  Also, other files work fine from this same disk.  I ran a smart test on disk3 and have attached that as well as the syslog.  Could someone be so kind and give it a once over?  Many thanks.

Smart looks fine.

 

Is the drive already red-balled ?

 

I've had the same problems, and they were fixed by replacing the sata cable. Sometimes reseating helps, but just to be safe replace the sata cable as well as the power connector (bad y-splitter?)

 

Other time I had this problem it was with an SFF-8087 cable which forced one of the sata connectors to "creep" out of the hdd after 1~2 weeks. It was barely noticable but it was not plugged in to the drive cage straight anymore.
