Here's an odd thing. When the 2.00 C firmware came out, I updated my Nerdseq just fine, and even made a video about making new cables for all the expanders I have 
In that video, you can see the filesystem check was OK
A few weeks later (now) I was doing another video where I wanted to load a previously saved project, but noticed I could not get into the Load Project menu: it just flashed at me. Being a QA guy and assuming it's just a developer oversight
I did come get the latest firmware v2.01? to try and see if that fixed the Load Project menu.
When I put the SD into the computer, I was greeted with the horrifying OS message "Cannot read drive. Initialize?" which of course I said no... all my projects are on that chippy... dummy me, never backed them up off the SD card (so yes, my mistake and I will now pay that price).
Taking the SD card back to Nerdseq without initializing or formatting, now I realize as it is loading, there is a filesystem error:
I am pretty sure all hope is lost at this point, my 30 or so projects are likely lost. I do not think XOR can magically fix a busted SD card
but I am mostly posting this to tell you this happened, which could just be a defective SD card (though it has lasted 2.5 years since I bought Nerdseq).
FWIW, I do power off and on a lot, but I am always extremely careful to not power cycle quickly and I do have surge protectors on all my gear... so I am unsure how this could have happened. I doubt it was the firmware upgrade, but just in case, here's some info for you.
I am going to reformat the SD now and put a ./firmware folder with the 2.01 release in there, and see if I am up and running again. I will miss my old projects, but nothing can be done so no sleep will be lost. It is what it is. Always Backup!
Thank you, as always, for such an amazing device.

Oh, one more piece of info why I think the SD card itself is just destroyed: both Windows 10 and MacOS report this drive as 32mb... not 16GB that it should be. Not sure if that'll ring any bells.
