Let’s start here : I see you have a Dell Precision 7550
- Do you know if the hardware is configured to push the bandwidth needed to drive a Monitor from DP => Thunderbolt 3 + a LaCie Rugged SSD Pro at the same time? You can check with the Dell website for that info, I cannot speak from memory. You’ll be looking for Bandwidth per port. Depending how many ports you have, 1port could be full bandwidth + Charging, other could be limited to slower speeds etc.
- This is a symptom of the first question I asked, It can be a bandwidth issue, but could lead to a driver issue. Thunderbolt can be iffy. . .
Do you have LUKS set up on this device? Did you format the device and it set up for root user only? (happens if you partition with gparted under the root account ) This can cause the mount issue ex:
I find I have issues after formating my drives, and have to set permissions to allow user and groups read/write after doing so I can unmount from nautilus.
Well, let me know what you would like to achieve, --key-file entry, configure /etc/fstab/ & /etc/crypttab properly, Fedora Workstation mounts drives from /run/media/<User>/Your-drive and in nautilus you can simply use 
+ notification of "
followed by “Safely Rremove device”
According to the Tech sheet you have a Mini DP 1.4 ? Why not use the DP => Mini DP 1.4 with an adapter ?

Some devices can bifurcate better than others, Intel has always had terrible bandwidth for devices. DMI is horrible. AMD just went with PCIe all the way. There could be a way to resolve this, but I cannot find a map of how Intel/Dell do Bifurcation on these models.
If Thunderbolt is straight from the CPU (it should be) Then there should be bandwidth to accommodate the Daisy Chaining of DP multiple monitors and have peripherals. They claim 4x4k Monitors on this model somehow.
You do not own the device, It’s owned by a user with higher privileges.
If you do not have any important data on the drive try this :
Set it to User ( I opened Nautilus as the root user and changed it. There are commands for this if you know them. ):
This has worked for me, in the past give it a try. I currently have this happen sometimes with USB Enclosures but not USB Drives. . .

Yep’ That is correct ! I have never asked why Fedora does this for OOTB Hotplugged drives. Every time I needed to work on it I was in a hurry, Vim :g was easier for me to fix the /etc/fstab & /etc/crypttab .
Poke around with the permissions, My USB/SS/USB-C drives work this way. We share a similar partiioning scheme too xfs
This. . . Has a more lengthy and complicated answer, I will throw a arrow in the dark here :
- In the BIOS Check if you have PCIe tunneling set to OFF/Disabled
this can change the behavior of the devices potentially being bifurcated in some way DP > TB3 + TB3 NVMe . . .
Could be drivers, could be device could be. . something else ( even Cables . . knock off cables exits. )
Using the UUID for the device and putting that into fstab for mounting would ensure it always is mounted under /mnt even when hot plugged. To avoid hangs if the device is not connected at boot time add the nofail option into the fstab entry.
It seems udev checks the fstab entries before auto-mounting under /run/media

I think udev manages all auto-plugging needs. I know it does the mount of flash drives under /run/media, and that when I put a line in fstab to mount an exteral USB drive in a different location by UUID that also automatically happens when the device is attached. This is how I manage my backup drive in a USB case externally.
Whether that also carries over to TB connections I have no clue.
Recently there was an issue with an external drive drawing too much power on a USB port and it would cause an already mounted flash drive to drop off when the other device was attached. This may be similar on the TBolt port if there is not enough power available to handle the start-up power surge without dropping the voltage too low and causing other devices to lose their config.
