This is an odd one that I can't figure out for the life of me. I am transferring a bunch of music from my PC to my Droid. I usually just drag and drop the mp3's into the appropriate directories I created. Everything copies over fine and I am able to play the files on my Droid through Windows Explorer. They play fine through the computer with no issues at all. I unmount my Droid and launch my music app. I can see the files and if I am fast enough accessing the music (after the unmount) I am even able to play a track on my Droid. But after a few seconds for some reason the artist information disappears from all my tracks and the songs are labeled no artist information. Then when I try to play the track again I get an error: "sorry the player does not support this type of audio file" And then I get kicked back to the main screen. I reconnect the Droid to my PC and open up the music directory and ALL the files are GONE. All the tracks are transferring over to the card fine. As I said I am able to play the tracks off of the MicroSD card through my computer. So the files are physically there an accessible after the transfer. I just have no idea why they are getting deleted? This is all happening on FroYo running BB 0.4. What I have tried: Copying same tracks from my computer onto my wife's non-rooted Droid. They work perfectly fine on her phone. Tried alternative music player besides the native Droid app - bTunes & MixZing Tried copying tracks over to the Droid using Double Twist formatted MicroSD card in both PC and in Droid and copied music files over first on the freshly formatted card. ALWAYS unmount before disconnecting USB cable. Tried a different ROM But nothing seems to be working. I copied over about 200 pictures to my phone (size ranging between 1-8mbs) and they all work fine. I am able to bring them up in my gallery and fly through them with no problem. It just seems like all my music tracks are getting deleted when I disconnect the USB from my phone. Any ides or suggestions for troubleshooting? Thanks in advance!
