# How do you hide disks from showing up in File Managers?



Relying on a fixed partition name is error-prone!
It's better to use UUID that are unique to a partition.

Get your disk UUID:

$ blkid

Get extended information:

$ lsblk  -o NAME,LABEL,UUID,MOUNTPOINTS,SIZE,MODEL

More extended information:

$ udisksctl info -b /dev/sdxn 
(where /dev/sdxn is partition). 

Write the following in «/etc/udev/rules.d/99-hide-disks.rules»:

# hide "Alien System" partition in UI
SUBSYSTEM=="block", ENV{ID_FS_UUID}=="UUID_of_Partion_To_Hide", ENV{UDISKS_IGNORE}="1"

The comments are optional, but recommended so that the UUID becomes 
less magic. Be sure not to mix up = with ==, one sets the variable, the 
other compares against a variable.

After creating the rules file, apply it by rebooting or by running:

sudo udevadm control --reload
sudo udevadm trigger --subsystem-match=block

Now run the udisksctl info -b /dev/sdxn command again and it should 
contain:

    HintIgnore:                 true


========================================================================

For fixed partition names, the general format is (this is case sensitive!):

KERNEL=="device name", ENV{UDISKS_PRESENTATION_HIDE}="1"

If it does not work, try:

KERNEL=="device name", ENV{UDISKS_IGNORE}="1"
