Thanks for providing the additional logs. As Sergio said, SMART is often unreliable on USB drives. What can happen, in very general terms, is that a proper SATA ssd is attached to a SATA-to-USB adapter. The adapter is not fully transparent to the SMART data, or it provides incomplete data, which may be enough for the vendor's "health monitor app", but isn't fully standards compliant, and so it can appear as failing.
I did a quick Google search for "sandisk usb Perc_Avail_Resrvd_Space" apparently that's a common issue for Sandisk USB drives. You may need to disable SMART monitoring for yours. If in doubt, do an extra backup :-) I doubt there's a bug in Ubuntu here, but if you believe otherwise please comment back with your rationale and we'll look at this again. I'm leaving this report marked Incomplete for the moment. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1953523 Title: KDE problem mounting Sandisk USB To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/smartmontools/+bug/1953523/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
