After upgrading to 7.5-pve2 smartmontools package I'm getting an error in email

Code:
Device: /dev/sdf [SAT], failed to read SMART Attribute Data

I've checked it out on the command line and it seems like if the drive hasn't been accessed recently I get this error...

Code:
smartctl 7.5 2025-04-30 r5714 [x86_64-linux-6.17.13-11-pve] (local build)

Read Device Identity failed: scsi error device will be ready soon

If I try again immediately after getting this error, it works normally.

Code:
smartctl 7.5 2025-04-30 r5714 [x86_64-linux-6.17.13-11-pve] (local build)

This drive is a backup drive running in a HGST Touro External USB enclosure which I have used with multiple internal drives over the years as I've needed to upgrade space. This is the first time I've had any issues and it started on reboot after the upgrade.

I think this might be due to some change in 7.5 smartmontools, but I can't find anything that seems to indicate what the change might have been that would have affected this. Has anyone else run into smartmon issues like this after the upgrade to 7.5? Any ideas about narrowing down what the change might be?
