Repairing library problem on E71

"There's an internal library of songs and their metadata. When the device is connected in USB mass storage mode, you can add and remove song files without the metadata library being updated. The USB mass storage is a block device and the phone has no visibility to the filesystem level operations performed on it.

When the Music Player app detects that the song files may have changed, it scans through the files to see if there are changes to be updated. Nothing wrong with that, but it can take a while, especially if you have a lot of songs on the device.

One possibility to get rid of the popup is not to connect in USB mass storage mode but use PC Suite mode instead and transfer songs using PC Suite's Music Manager. That way the device can keep track of actual changes on the filesystem."
