Drive Read errors

I just built a system with brand new Iron Wolf 8TB drives and several are throwing the occasional read error out.  One drive has been kicked out of the share twice and I'm in the process of returning it as I feel that several hundred read errors are a bit excessive.  My first drive had 1 or 2 read errors and hasn't any since.    Right now, a 3rd drive just thew out 8 errors after behaving for almost 2 weeks.    When I run the SMART tests on them, it finds no errors.    If find it hard to believe so many drives could be faulty right out of the box.   My 10Tb Iron Wolf parity drive has been a champ.  A

 

I'm running Unraid 6.9.0-rc2 and my 5 drives are going thru an HBA (the drives didn't come with SATA cables like I expected).  Could that be the issue?  Is there a setting to raise the threshold for a drive getting marked disabled?  I'm expecting my new drives to arrive tomorrow and need to hold out until then.  lol

 

THanks.

THis is the result of the short test.  The long test is still running.  I attached a screen print as the below text is poorly delimited.

Diagnostics would have given us everything you posted there plus everything else we asked for.

Got the firmware updated.   I opened the case to add M.2 cache and it seemed like the SAS cable had a subtle click when I checked the connection.  That might've been the problem.

 

Everything ran fine for about 16 hours and then I got another set of 8 errors on the same drive as yesterday as well as 1 error on a 2nd drive which kicked it immediately out.    Maybe it's the cables, maybe it's the LSI card.   I'm kinda getting the idea it's in the LSI HBA.  I ordered new cables and I'm about to switch to some unused LSI cables.    Gotta wait for the pre-clear to finish on the new drives I added.
