January 4, 20224 yr Hello, recently I have been getting read errors on a few disks. Been using the same setup for years now, slowly adding drives over time and never had this issue before. One drive already became disabled due to this and I rebuilt it successfully. Now another drive has become disabled because of this. The drives it has been happening on are mostly newer ones. However, the second one to become disabled because of this, I have been using for over a year. I've read that this is more commonly caused by a bad connection instead of the drive. I'm wondering where I should start or if anyone has any tips for me on this. I have a 4U supermicro chassis and my drives are plugged into a backplane (BPN-SAS-846A). I believe I have 3 LSI 9210-8I that the backplane is plugged into. Since this is a more recent issue is it possible my issue could be caused by one of the LSI cards that I am now starting to use more due to the new drives? Edited January 7, 20224 yr by Chandler

Silly that Seagate has this issue. I went through and completed all these steps after I rebuilt the disabled drive. EPC and low current spin up are off on all my ST8000VN004 drives. My drives are still getting the read errors though. Any more ideas? Here is a new diagnostics if that helps. tower-diagnostics-20220107-1445.zip Edited January 7, 20224 yr by Chandler

January 10, 20224 yr Community Expert If disabling EPC and low current spin up didn't help you'd need to use a non LSI controller, or different disks.
