There are 2 versions to this problem:
I've formatted this thing about 2 times from the player, re-importing my data to it after, because I get a "Damaged SD card" error if I let it go on for too long after seeing some music disappear. That can't be right though; this same error has happened with another SD Card. Sometimes after getting that warning, turning the SGP on/off negates it. Also, if I plug the player into my PC through USB, I can still see files, and the "GB used" count on the card is the same as if it had the files. Around the time these issues happened again after the second format, I figured out that the player sometimes sends music to the LOST.DIR folder, with a different filename where it's unrecognizable. That's the first version.
Thanks to this, I formatted a third time, this time using Windows' formatting instead of the one on the phone. Things seemed to go OK, but then the battery ran out one day. I recharge, and turn the player on to see some music files deleted. Not moved into LOST.DIR. Permanently deleted. I haven't gotten "Damaged SD Card" yet. That's the second version. I don't know what to make of this.
There are several possible causes to this problem:
-The main cause seems to be turning the player off. It seems if the player goes off without the SD card being unmounted (through low battery or some random reboot), my music files are now living on borrowed time. However, that's a really stupid cause IMO. This player can do so much, but it somehow goes crazy on ONLY my music when the player gets turned off without an unmount? Something else seems to be up.
-I use Poweramp to play my music on the SGP. Maybe it's doing something that automatically kicks files into LOST.DIR or deletes them. I haven't been able to find that setting though. I delete music through this program as well. Maybe it's bad at that. I don't know.
-I use Winamp to import music to my SGP. It organizes music into a nice structure with an artist folder, an album folder, and the songs within that. All the audio, however, is housed in a folder I made called Audio. Could anything about this structure be throwing things off?
Has anybody else gone through this problem? This player is awesome enough to suffer through this, but I don't know how many re-formats and re-imports I can take.
