External expansion drive is recognized by lsusb and dmesg, but not fdisk or lsblk

Unix & Linux Asked by rarelyNecessary on December 6, 2020

I have a Seagate SSD expansion drive that I haven’t used in a few months that I’m trying to plug into my laptop (Lenovo Yoga 460 running OpenSUSE Tumbleweed). When I plug in the expansion drive, I’m not able to access it, and I think it’s making a faint beeping sound but I can’t quite tell.

It’s being recognized by lsusb:

Bus 002 Device 002: ID 0bc2:231a Seagate RSS LLC Expansion Portable
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 138a:0017 Validity Sensors, Inc. VFS 5011 fingerprint sensor
Bus 001 Device 003: ID 04ca:705a Lite-On Technology Corp. 
Bus 001 Device 002: ID 056a:504a Wacom Co., Ltd 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

And when I run dmesg | tail - n 20 after plugging it in, I get messages about it being recognized:

But when I run sudo fdisk -l, there’s nothing listed for it, just my main laptop hard drive and the SD card I have inserted:

Partition table entries are not in disk order.

Similarly, when I try to run lsblk, there’s nothing listed there out of the ordinary:

└─mmcblk0p1 179:1    0  14.9G  0 part 

Is there a way that I can still mount the hard drive?

EDIT:
Also doesn’t show up with lshw -class drive:
