But with another drive of the same model, everything is fine.

Same Revision: C3D0 and Compliance: SPC-4?
Same controller used for device access?

PS: Please do not set the Milestone in future submissions.

Replying to Christian Franke:

Yes, same revision, compliance and controller Intel RS25SB008

[Christian Franke]

Please provide outputs of smartctl -r ioctl,2 -a /dev/bus/0 -d megaraid,N for both devices as attachments to this ticket.

[padner]

Thanks for the answer, Christian!

I added attachments

[Christian Franke]

Changeset r4958 adds workarounds for bogus log directories from Samsung SAS SSDs (see tickets #1225 and #1239). It may also affect the output of these HGST SAS HDDs. Please test if possible. Tarballs with source and binaries are available at ​https://builds.smartmontools.org.

[padner]

Thank. I tested version r4965, but there is an error, attached files

[Christian Franke]

So recent commits did not change the result:

smartctl -d megaraid,44 ...: Exits with 4 because the following SCSI commands fail:
READ DEFECT DATA (12), and
LOG SENSE of FORMAT STATUS LOG PAGE (08h/00h).

smartctl -d megaraid,45 ...: Exits with 0 because all commands succeed.

The commands sent to both disks are identical. So this is likely not a bug in smartctl.

Are these disks possibly in different modes (RAID vs. Spare disk, Active vs. Standby power mode)?

[padner]

Hi, Christian.

Yes, they have different modes.

44

Firmware state: Hotspare, Spun down
Inquiry Data: HGST    HUH721212AL5204 C3D08DG4KATZ 

45

Firmware state: Online, Spun Up
Inquiry Data: HGST    HUH721212AL5204 C3D08DG5TYVZ        

If disable controller feature "Spin Down of Hot Spares", drive firmware state change to "Online, Spun Up" and smartctl return 0

ps sorry for the long answer

[Christian Franke]

SCSI commands failed because the disk was spun down. This is not a smartctl bug.
