Hi there! Just put together my first gaming machine that runs Linux. The motherboard has three M.2 slots. Two of which are populated:

1. 1TB Western Digital Black (boot)
2. 2TB Samsung Evo (storage/backup)

I currently have Timeshift backing up to successfully to drive 2. However, I was going to try out Deja Dupe as a more granular backup solution and realized that I can't see the 2nd drive when viewed through Files>Other Locations. GParted sees both:

1. /dev/nvme1n1
2. /dev/nvme0n1p1

In Deja Dupe I was able to manually type the backup destination in and it appears to have worked on initial backup. But I can't see the drive via Files in order to verify.

Does Timeshift highjack the volume entirely for it's own backup purposes? I couldn't find anything anything that indicated that was the case. I did see some threads on that other site referencing a potential bug if it did NOT show up in GParted. But not what to do if it does.

Additionally, I built this machine in a Fractal Terra case and it has a USB C and a USB A port on the front of the case. I have a Lexar thumbdrive that has both plugs on it, one on each side. Occasionally I can get it recognized via A or C port, but most of the time the C port doesn't work, period. The A port I just tried again and it doesn't work. But I have the Logitech Unifying Receiver plugged into the same port right now that is communicating to my mouse and kb. The ports on the back are also now not working (they were before). I tested this same thumb drive on a Macbook Pro and it is recognized. In fact, this is the same drive I installed Pop from when I built the thing. I also used it to try out EndeavorOS.

For thoroughness I tried an external SSD I have via USB A and that is also not recognized. I'm not familiar enough with how Linux handles storage to understand what is happening. But it seems at least the internal NMVE is "working" but not visible outside of the automated Timeshift backup.

Any help would be appreciated. Or a log I can start looking at?

Oh, and I don't know if it helps but Neofetch shows all the hardware correctly.
