The problem was not present before version 216 (Fedora 21). I have also confirmed the problem in Ubuntu 15.10. This means all the file managers ignore the disks and they can't be mounted via udisksctl (udisks2). They can still be mounted via the mount command or udisks.\r\n\r\nAlso, there's an error in the journal when the disks are inserted.\r\n\r\n```\r\nmar 19 02:10:39 warlock.net01 kernel: sr 0:0:0:0: [sr0] tag#5 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE\r\nmar 19 02:10:39 warlock.net01 kernel: sr 0:0:0:0: [sr0] tag#5 Sense Key : Medium Error [current] \r\nmar 19 02:10:39 warlock.net01 kernel: sr 0:0:0:0: [sr0] tag#5 Add.

It just happens to be the default in K3B. Other people are using Easy CD Creator in the reports.\r\n\r\nThank you and best regards.\r\n\r\n\r\n\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/systemd/systemd/issues/comments/198692136","html_url":"https://github.com/systemd/systemd/issues/2872#issuecomment-198692136","issue_url":"https://api.github.com/repos/systemd/systemd/issues/2872","id":198692136,"user":{"login":"robertxgray","id":9676118,"avatar_url":"https://avatars.githubusercontent.com/u/9676118?v=3","gravatar_id":"","url":"https://api.github.com/users/robertxgray","html_url":"https://github.com/robertxgray","followers_url":"https://api.github.com/users/robertxgray/followers","following_url":"https://api.github.com/users/robertxgray/following{/other_user}","gists_url":"https://api.github.com/users/robertxgray/gists{/gist_id}","starred_url":"https://api.github.com/users/robertxgray/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/robertxgray/subscriptions","organizations_url":"https://api.github.com/users/robertxgray/orgs","repos_url":"https://api.github.com/users/robertxgray/repos","events_url":"https://api.github.com/users/robertxgray/events{/privacy}","received_events_url":"https://api.github.com/users/robertxgray/received_events","type":"User","site_admin":false},"created_at":"2016-03-19T12:14:42Z","updated_at":"2016-03-19T12:14:42Z","body":"I have written to the CD again to finalize the multisession.\r\n\r\nBefore\r\n```\r\nE: ID_CDROM_MEDIA_SESSION_NEXT=2\r\nE: ID_CDROM_MEDIA_STATE=appendable\r\nE: ID_CDROM_MEDIA_TRACK_COUNT_DATA=1\r\nE: USEC_INITIALIZED=28425\r\n```\r\n\r\nAfter\r\n```\r\nE: ID_CDROM_MEDIA_SESSION_LAST_OFFSET=483917824\r\nE: ID_CDROM_MEDIA_STATE=complete\r\nE: ID_CDROM_MEDIA_TRACK_COUNT_DATA=2\r\nE: USEC_INITIALIZED=71456\r\n```\r\n\r\nBut still no ID_FS_* attributes in udev :disappointed:"}}
