I accidentally pulled the USB cable out when the internal MMC of the n900 was mounted. I saw the name of the device change to "BCM2048B0 Initialization Configuration" http://talk.maemo.org/showthread.php?t=36556

I ran fsck which I think did something. Now there is a file called " ._" filled with junk.

The media player reports it can't find any songs or videos. Additionally, I cannot play the mp3's from the file manager which I think you could do before. I know the mp3's are there and valid because I can use panucci to play them.

Anyone know how to fix this? I'm guessing there is a link missing or something similar.

I have this same problem. I also get the message "(no images)" in the Photos application. I can also play my media with Panucci and can open the photos from the file browser.

I also have received the message...
Retrieving information on the new media files.
Estimated time remaining: 03:00
when I open the media player. Waiting the three minutes doesn't seem to change anything.

I don't think I pulled out the USB cable without ejecting it, nor do doing so should cause a problem like this.

I've reset the phone many times, taken out the battery, and connected and disconnected USB a couple times.

Argh!

Try resetting the tracker database.

Thanks for the very quick reply! I did a little more searching and found this thread...
N900's own media player not finding any of my well... media
I had just came back to this thread to link to the other one. The tracker reset and restart fix worked for me too.

Thanks again schettj!

had this problem after flashing with pr 1.2 emmc was corrupted. formatted the .docs right from the file manager, copied mp3s from Shared Files via wifi but got a no songs error in mplayer. anyway schetjj's solution worked great thanks!

tracker reset worked for me ! thanks !!!

i did th tracker reset in xterm and after some checking, removing and checking again it gave me (could not find index file : /home/user/.cache/tracker/file-index.db) and also (email-index.db)
i also tried the hard reset and Failed !!

The same problem here tracker reset didn't work
any suggestion guys ?

Dunno what to say but yo guys cant try reinstalling your codecs and or checking if those files:
/home/user/.cache/tracker/file-index.db
/home/user/.cache/tracker/email-index.db

Actually exist, if they don't exist, then maybe someone can try to upload those files (file-index.db, and email-index.db) to try and remedy the problem.

I tried "tracker-processes -r" --- It dint worked first
then i change user to root and run same command again and it worked...
