Questions.  What should a person do to prevent this from happening? Plug 
the USB stick in on occasion for a few minutes, so it can 'recharge'??  
Should one do something else to prevent this?  Should one mount the file 
system?  Do something to the files to make them rewrite?

The reason I ask, I store backup data on m.2 sticks, USB sticks and such 
so that if I have a system crash, they would be much needed and 
quickly.  I store them in a fire safe.  I usually only plug them up when 
I need to update them.  Since I store things like the world file, 
passwords that I rarely change, they are not plugged up very often.  
That said, I also use USB sticks for bootable ISOs as well, like the OP 
does to it seems.  Those can sit untouched for a while.

Just curious if there is a way to prevent this.
