I'm happy to hear that you've got the defective drives replaced. The other two issues you mentioned do not seems related to the smartmontools package, so I'm marking this bug report as Invalid, as it wasn't a bug in the first place. I suggest you to file separate bugs against the relevant KDE packages if you think you spotted problems there.
I am sorry for somehow hinting you at dismissing an hardware failure warning in comment #4. What I wrote there _does_ match my experience with USB drives, but I should have added a warning about smartmontools possibly being right, so extra care was required with your data. ** Changed in: smartmontools (Ubuntu) Status: New => Invalid -- 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
