Greetings! This is my first time using Unraid and I'm seeing some disk issues. I ordered 10 Used HDD's from the same Ebay Vendor. They are in a refurbished Dell T620. The disks are connecting to a H710 controller that I flashed to IT mode. I've attached the diagnostics from UNRAID. Hopefully I'm just missing something simple.

 

 

I see similar errors to what is below for 7 of the 10 disks so far. One seem to be running the preclear without any issues.  I had initially added the disks to an array but the Parity-Sync quickly shot up to 35+ days(3tb drives 2xparity) . I canceled that and decided to try and run the pre clear on each disk. The smart check shows that the disks are "healthy" but not sure that its correct.

You need to remove this from the disks, more info below.

thank you sir! I found the link to the tales from IT post and will give that a shot! Will update if it works.

Where did you find the Formatted with type 2 protection info in the diagnostics so I know where to look in the future

The syslog errors suggested that:

and you can confirm by looking at the SMART reports for the drives.

Thank you! That did the trick.
