I tried on a random lab machine with 2x HP MM0500GBKAK disks. With 6.5.0-18-generic:
Before: SMART Attributes Data Structure revision number: 10 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE ... 4 Start_Stop_Count 0x0032 100 100 020 Old_age Always - 293 ... 12 Power_Cycle_Count 0x0032 100 100 020 Old_age Always - 293 ... 192 Power-Off_Retract_Count 0x0032 100 100 000 Old_age Always - 292 ... and after: SMART Attributes Data Structure revision number: 10 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE ... 4 Start_Stop_Count 0x0032 100 100 020 Old_age Always - 294 ... 12 Power_Cycle_Count 0x0032 100 100 020 Old_age Always - 294 ... 192 Power-Off_Retract_Count 0x0032 100 100 000 Old_age Always - 293 ... Seems Power-Off_Retract_Count increments regardless. I rolled back to 6.5.0-15-generic, and saw the same behaviour. I think I need to try a different lab machine with different disks.

I also noticed the "click" of the head parking when shutting down the computer. By restarting the computer with previous kernel version (6.5.0-15.15~22.04.1) the issue didn't happen, so I assume it's a kernel bug, that causes it to shut down the computer before hard drive is deactivated ProblemType: Bug DistroRelease: Ubuntu 22.04 Package: linux-image-6.5.0-17-generic 6.5.0-17.17~22.04.1 ProcVersionSignature: Ubuntu 6.5.0-17.17~22.04.1-generic 6.5.8 Uname: Linux 6.5.0-17-generic x86_64 ApportVersion: 2.20.11-0ubuntu82.5 Architecture: amd64 CasperMD5CheckResult: unknown CurrentDesktop: XFCE Date: Tue Feb 13 16:35:55 2024 InstallationDate: Installed on 2020-10-02 (1228 days ago) InstallationMedia: Ubuntu 20.04.1 LTS "Focal Fossa" - Release amd64 (20200731) SourcePackage: linux-signed-hwe-6.5 UpgradeStatus: Upgraded to jammy on 2022-08-11 (550 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2053041/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
