Trying again.

[hmorgan1979]

I tried to get assistance before and it seems as though the request, after a bit of back ad forth, never got resolved, so here goes: I have a Toshiba 2TB external hard drive, and an Acer Aspire laptop. I am currently running Ubuntu Studio 18.10. My problem runs thusly: about three months or so ago, everything was fine. My external hd was working fine with my laptop. One evening I had unplugged the hd from the laptop because I was going somewhere. I returned the next day and hooked everything back up. My hd doesn't show up on my desktop or in the device list. I have tried with a different usb cable and still nothing. I ran lsusb and the results are below:

herman@InfernusMaximus666:~$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 8087:07dc Intel Corp.
Bus 001 Device 004: ID 064e:9404 Suyin Corp.
Bus 001 Device 003: ID 0bda:0129 Realtek Semiconductor Corp. RTS5129 Card Reader Controller
Bus 001 Device 009: ID 0480:d011 Toshiba America Inc Canvio Desk
Bus 001 Device 002: ID 046d:c52b Logitech, Inc. Unifying Receiver
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub


The Toshiba Canvio is the external HD.

Then I unplugged it, plugged it back in and ran dmesg | tail -n 20. again, results are below.
$ dmesg | tail -n 20

Again, the Toshiba shows up. This is where everything stands at this point.
Any help would be greatly appreciated.
