I discovered that the photos I took disappeared from gallery.
The same with video.
When browsing to a video file and playing it through Astro the file reappered in the gallery, but only the one played.
The media files on my external SD were still visible.
After a bit of messing around the External SD files disappeared too.
Both the internal and external SD cards are mounted and I can browse through them using Astro but the Gallery and music player doesn't show anything.
I then installed SwithcPro Widget which can activate the media scanner.
The media scanner runs, but the files still won't appear in gallery / music player.
I'm running MCR FR10.
Just updated the baseband to the latest version and restored everything from backup.
I really don't want to delete everything and start from scratch, but unless someone in here can help me I'm afraid that's my only choice.
