External USB HDD connected to RPi 3B +

Probably there is a config boot file that I could set to not mount automatically the unity usb HDD.

But that will not stop the HDD to “start” it will just stop it from mounting!
To avoid automouting of just one of 2 drives you would have to reconfigure udisk.glue.
Alternative is to mount your fist disk via fstab and disable udisk-glue overall.

Prevent automount of partitions by uuid

Hello, Is there a way to prevent partitions (identified by uuid) from automounting (when an external disk is plugged in) ? It can be done with udev rules on Raspbian. OSMC uses different tools to handle automount (a package called udisks-glue is installed). On Raspbian in udev rules I just set ENV{UDISKS_IGNORE}:="1" On OSMC I tried similar rules, with UDISKS_PRESENTATION_NOPOLICY instead of UDISKS_IGNORE, to no avail.

Avoid automount external units

Hi I like to avoid auto-mounting external drives when osmc boot or plug any unit. I like to mount units manually. Thanks in advance
