[nmglug] Weirdness

Thanks Jared. I ran the test and the output is below. The SSD is a 1TB 
Western Digital less than two years old. I had installed a clean Ubuntu 
18.04, which I'm still running. I copied over my files (no conf ones 
though) and everything was fine until about a month ago now.

A weird thing that I didn't bring up is that when I check the boot setup 
(F2 or F12 on startup) I find my user name, ubuntu, listed as a device 
and it seems to always end up at the top of the boot order. I don't know 
what it is or how it got there. It's obviously not a drive of any sort. 
When I change the boot order to my SSD all goes fine except for the 
issues I have already stated. But I really want to thank you and really 
don't want to lose my SSD! But if that's what is happening then nothing 
left to do. I hope this output gives you some idea.

Thanks again

Brian
