I don't think it's fake but it's the lack of partition being the main issue.
I've just reconnected it to the previous system and found this in history:
sudo mkfs.exfat /dev/nvme0n1
sudo mkdir /mnt/nvme0n1
sudo mount /dev/nvme0n1 /mnt/nvme0n1
I think the fact that it reported as nvme0n1 cofused me and made me
think it was a partition.
All of the above worked and I was using the drive for days.
I ran: rsync, ls, df, cd, rm, rmdir and other commands.
Everything felt perfectly normal.
Now I'm unable to remount it the same way:
sudo mount /dev/nvme0n1 /mnt/nvme0n1
mount: /mnt/nvme0n1: wrong fs type, bad option, bad superblock on
/dev/nvme0n1, missing codepage or helper program, or other error.
I think it's time to give up on the data and move on...

There are fake 4TB drives in the market. Maybe you got one? There are some
tools available for checking this (I believe, in Debian there is a tool called
"f3" or similar.
If there are no important data on the drive, you might reformat the drive to
ext2/3/4 and then use "resize2fs" to corect the settings of your drive. In the
past I used to grow a partition with gparted, and gparted showed correctly,
but df showed still the old size.
Resize2fs then did the trick and I got the correct size.
If you have Windows on an other computer, there are so,e windows based tools,
which are made for testing the real capacity of your drive.
Additionally I got such a fake 4TB drive. Although the tools al showed "fake",
I could fill it with almost 4TB. Inside was of the case was an USB-stick and I
think, the capacity is made by software (shrinking files, double space
whatver). However, this stick is (USB-3!) raaaaaaather slow!
Just some thoughts, maybe it helps.
