Looks like this is already reported upstream: https://github.com/storaged-project/udisks/issues/732
It's more than 2.5 years that the bug doesn't get attention/activity, so I'm marking this Ubuntu bug as having Low importance due to low user impact. That bug mentions "it's a QEMU issue in the way the CD-ROM device emulation is done", but I unable to verify if this is true or not. ** Bug watch added: github.com/storaged-project/udisks/issues #732 https://github.com/storaged-project/udisks/issues/732 ** Also affects: udisks via https://github.com/storaged-project/udisks/issues/732 Importance: Unknown Status: Unknown ** Changed in: udisks2 (Ubuntu) Status: New => Triaged ** Changed in: qemu (Ubuntu) Importance: Undecided => Low ** Changed in: udisks2 (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to udisks2 in Ubuntu. https://bugs.launchpad.net/bugs/1993356 Title: udisks doesn't make sense from cdrom Status in udisks: Unknown Status in qemu package in Ubuntu: Triaged Status in udisks2 package in Ubuntu: Triaged Bug description: udisks doesn't make sense from cdrom there are journal errors from sending ATA command IDENTIFY, maybe incomplete kernel or qemu support?
