i put music onto the sd card, i go into my media files, then media card, and no music....then i hit epxlore wich brings up media card and device memory, i hit media card and presto ,,,my music is in there, but when i open the file it says unable to play,,,i put the card in another phone and it worked just fine...any suggestions? im super confused...i was at it for hours but cant figure it out,,please help!!!! thanx.

Make certain the BB is unplugged from the USB cord and the PC when you look for the music via the BlackBerry... media files on the Media Card won't appear when viewing from the BB while it is plugged in.

i did have it unplugged, and i even pulled the battery so i would reset, still the problem kept coming back, any other suggestions?

Were the music files DRM iTunes? Those won't play on a BB...

If need to do, reformat the Media Card and start again.

I have a friend that has a pearl.. his does the same thing, although mine shows up like it's supposed to..
The guy at tmobile told us... well I can't remember what he told us!
I think it's just something that "just happens" It might be the type of file it is...

haha too bad this post isn't of much help.. although I've seen it, and the music files still played for him... he just had to pull em up all weird

I've had no problems with media on my 8100, but I only use MP3's. Are your files in another format?

tey are mp3's, at one point it said that it was read only, not sure what that meant, it was unplugged from the comp. they do play on my friends pearl just fine.

If the files are "read only" they won't play. I don't know how to change that either. I once transferred songs from a player to my pc and the "read only" ones would never play. I could never get them to play no matter what I did.

check to see if they are read only on your PC. right click on the files, select "properties", and down towards the bottom of the popup properties window is a read-only checkbox. make sure that is un-checked, and transfer the music over again.
