According to a redhat bug report (https://bugzilla.redhat.com/show_bug.cgi?id=1310682) it was introduced by a kernel update from 4.3 to 4.4. So I've testet 4.3.6 from mainline and it is not effected.
Btw. you probably get this on a live system too and for all hdds (since root is on the flash drive). This can have quite an impact, because some DEs automatically mount all removable drives (e.g. kde). If one of your hdd partitions contains a hypernated system, your in for a lot of fscking and/or ro mounted partitions on next resume. ** Bug watch added: Red Hat Bugzilla #1310682 https://bugzilla.redhat.com/show_bug.cgi?id=1310682 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1568352 Title: "/sys/block/sd(X)/removable" erroneously indicates "removable" for fixed drives Status in linux package in Ubuntu: Confirmed Bug description: This seems to happen only to additional hdd (not the one with the root partition). gnome-disks and some file manager report those drives as ejectable.
