Help recovering crashing SD card

[riz94107]

I have an Odroid-C1+ running some version of Armbian (I forget the details, exactly) - it's been happily working for a while, but recently that board went dead.  I finally got a serial console on it, and captured the output below.   Pretty clearly, something is wrong, and it being a cheap flash card, I bet the card itself is going bad.   My real question:  does anyone have a good suggestion how I can recover anything there is to recover from the SD card before setting up a new one?  It's been long enough since I set up this device that I'd prefer not to start from scratch if I can avoid it.

 

I'm not much of a Linux guy (usually NetBSD/MacOS), but I do have a  Ubuntu 16.04LTS VM I can use for mounting - but I'd love any suggestions how to maximize my chances of having something recoverable...  Thanks!

Buy a new SD card and reinstall it with Armbian (the current version/origin or the new update)
Restart your O-droid with the new SD card and do the basic config (name, network)
With a SD/USB card reader, connect the old card to your O-dorid
Retrieves what is still readable and makes the copies directly where is needed on the new SD card
