I was recently given a used external SSD and I want to connect it to my laptop, which is running Ubuntu 20.04.4 LTS. When I connect the SSD via USB, Ubuntu does not seem to detect it. I do not know how the SSD was previously formatted or with which OS it was used.
No sign of the drive in Files (the file manager) or Disks (the partitioning tool). No sign of the drive in lsblk output.
It appears to be represented by this line in the output of lsusb:
Bus 004 Device 052: ID 0525:338a Netchip Technology, Inc. Envoy
And here's the output of dmesg after connecting the SSD:
