I'm getting SMART errors on SAS/SCSI disks.  

I also have the same problem with a different SAS/SCSI drive.

There's also some drive intermittent drive buzzing noise that seems related to accessing the GUI self-test web page.  I also think I get disk temperature warnings from this web page/screen too.

 

This is an unmounted disk, no data, zero'd.

 

I've run pre-clear, and there's no reported errors.

 

I'm new to SAS/SCSI, so I don't know what normal should be.  I don't see the same same kind of SMART information on SATA drives.

 

The "Errors Corrected by ECC" are very concerning to me, but I don't know if that's bad, normal, an uncorrectable problem.

normal,

It's normal, SAS SMART is very different from ATA SMART, from my experience, which is not much with SAS, you wan to monitor "Elements in grown defect list" and "total uncorrected errors" which should both stay 0.

Might "blk_update_request: protection error" or "Buffer I/O error" be a problem?

Problem yes, but not necessarily a disk problem.
