I've been running Rockbox on my 160GB Classic for a while now and I've just upgraded to emCORE r867 and 121007. So a big thank you to the developers!
All is fine except when I try to build the database of tracks so that I can have random playback - Unfortunately it gets to about 1100 tracks (out of around 6000) and hangs and I have to reboot. It does this at the same point every time that I try so I guess that I have a corrupt music file.
Is there any way of logging the progress so that I can find out which file is causing the issue?
Take a look at the rockbox bug section. You can take a look if your bug's already been listed.
