USB HDD not visible in nautilus/nemo

Question

The HDD is visible in the 'disks' utility. I can mount the one and only partition on that drive using mount. gvfs-mount Recognizes the disk:

$ gvfs-mount --list
...
Drive(2): 750 GB Hard Disk
Type: GProxyDrive (GProxyVolumeMonitorUDisks2)

dmesg looks like this:

The disk isn't visible in nautilus' "Devices" category. Other USB disks are visible and I can mount them with nautilus. That particular drive used to work with nautilus two months ago.

The only partition on that disk is formatted with vfat. I tried rebooting and it hasn't helped.

Edit: the drive is also invisible in dolphin, so there seems to be some underlying issue.

Well, it is a bit late but for others....

You can probably look up in the udisks2.rules in /usr/lib/udev/rules.d/80-udisks2.rules and remove anything or all which comes after

# ------------------------------------------------------------------------
# ------------------------------------------------------------------------
# ------------------------------------------------------------------------
# Devices which should not be display in the user interface

as your disk probably triggers one of those conditions. Alternatively, try removing some parts at a time.
