sansa e280 v2 issues...

[crossrunner99]

I didn't really know how to classify this problem, but anyway:
  I have successfully used my player for about a year.  At one point I inserted a 16GB micro SD card with about 8g of music on the card.  it worked fine, but due to unrelated issues I had to get another card.  I loaded about 12g onto this card before inserting it, then tried to use it.  The player stops dead after varying amounts of time, frozen.  I tried reformatting the card, and I'm going to try a new rockbox version (mine older). 
     **I don't have much experience troubleshooting this thing, and I have no idea what is causing this.

Does the original firmware also have trouble with this card?

So first off, the original firmware has no issues.  Strangely, neither does rockbox...
 Several days ago in a vain attempt to make the thing work, I wiped the card all except for a few hundred megs of music and it worked fine.  Realizing later in the day I was no longer able to troubleshoot my problems, I added 10 gigs of music to try to recreate the problem.  Everything ran fine on the original firmware, and other than some database cataloging issue ran fine on rockbox.  I then reloaded the same files I originally had onto the card yesterday and so far it had been running fine. 
 
 I have also noticed some peculiarity in the database where it saved multiple entries of one song.  when it compiles a database, there can be at least five links to the same file.  I think this could have something to do with the problem, especially because I have not created a database for its current files yet.

The duplicate entries in the database is probably just this bug rearing its head:
