A few weeks ago I started getting read errors on three new-to-me drives that I recently picked up. These drives are all older 8tb Seagate Archive drives which I picked up off of someone in an unused state - they only have <2 months of power-on hours.
I am only getting these read errors near the end of parity checks and only on these drives. The drives were pre-cleared without issue before having them be put in.
I am currently using a supermicro SC846 case with a SAS2-EL1 backplane and an LSI 9205-8i HBA with both cables plugged into the backplane. I thought the added drives might be stressing the HBA so I added a 40mm fan to it with no change. I have also tried reseating the HBA and the cables, as well as changing the slots the drives are in. The odd thing is that all 3 usually have identical levels of read errors, sometimes only a few and sometimes tens or hundreds of thousands.
The drives all pass extended SMART tests and don't seem to have any other issues.
I have no idea what the issue could be here - I really doubt all 3 drives are failing in the same way at the same time but I don't see another issue? Could it be the HBA? if so, why only these drives?
