When my player arrived I placed my sdcard in turned it on which DX50 began to scan, it stayed scanning for a very long time over 10 minutes, 15 minutes, 20 minutes, being a new owner and not reading any posts about this phenomenon I thought might of been normal, though I became tired rather quickly resetting the player. I turned it back on went straight to browse folders (stuff the scanning I thought) where it would play music but sometimes not in order and also would do a quick scan of each new folder I played once.

On the next boot being scared of the scan button I pressed it anyway which it did so for about 30 seconds (if that) and I've never had a problem since never got stuck again. My music plays in order, all my FLAC folders play (I did no tag cleaning), when I add new folders via PC it just does a quick scan on start up and everything plays sweet.
Overall so far I really enjoy DX50, we're becoming good pals together, a purchase well made, especially knowing support is around to improve on the DAP further,
