Here is my experience, which may or may not be pertinent.

I had a first gen iPod shuffle, basically a 512 MB flash drive with music player.  
During a file transfer, it locked up and I could never get it back with any of 
the tricks that google provided me.

So I left it on.  I am not sure what this means because "On" is more like 
"unlock", as it isn't really "on" unless it is playing and the file system 
corruption prevented it from playing.  I left it on for six months.  Still had 
a charge and wouldn't play.  I left it on for about 13-14 months.  Charge 
gone.  Erased.  Plugged in. Reloaded music.  Worked fine

So an extended time with no power, at least on this device, does result in a 
loss of data.
