Is this anything to be worried about? I just saw this errors.

Thx in advance

Check that the power connection and the SATA cable connections are well seated.  These type of errors tend to pop up with either of those being the culprit.

 

Post a full system spec and we might be able to point out what might be causing the issue.

Just to add, I started getting the same errors when I upgraded to 4.6. I've reseated the cables, ran a Long Smart test and everything was fine. Can this be something with the new version of unRAID?

 

I'm curious if re-seating the cables will work for slarco.

Bump, curious what else this can be aside from cables or connection.

 

Did re-seating the cables fix the issue for you slarco?

This is def a drive related issue and not something specific to unRAID. It might be that a newer kernel is in  unRAID that has "tighter" timing then the older one.

 

Also, the above snippet shows SATA 6.0Gbps and it might be an incompatibility between the disk being SATA 2 (i.e. 3.0 Gbps) and SATA 3 (i.e. 6.0 Gbps).  I have heard of SATA 3.0 Gbps drives not working properly on SATA 1.5 Gbps controllers until the drive was jumpered to run at only 1.5 Gbps speed.
