It happened a few times before but now it's happening everytime I reboot the device and the only way to avoid this is to disconnect my external HDD and boot without it and then connect it. But like this, I have to wait every time for it to scan the whole HDD which takes a lot time. If I start the Pi with HDD connected, RuneUI shows volume at 100, and I can't change it, it keeps returning back to 100 and MPD doesn't react on buttons. I can create playlists and navigate through RuneUI but pressing Play won't do anything. I tried to run "mpc status" and it gives me Updating DB #2 status and it says Volume: n/a.
Before it always worked, after each start, there was a small updating but it worked while updating. Is it possible that I broke it somehow because I was installing a lot packages to enable LIRC and WiringPi? How to fix it?
I just wanted to ask if maybe somebody had same problem or if there's some way to reset/reinstall MPD or something. Problems are meant to be solved, not to be avoided 
I can't just rollback everything because I will probably mess it again when I do all this again, and I just want to have that LCD display, buttons and IR remote. But I'll definitely try everything again on a clean install of RuneAudio. Otherwise, I'll try to disable rescaning, this would be a decent solution since I don't update music very often. Also, to update it, I must unplug the disk and plug it into my laptop. When I plug it back to RPi it will update anyway.
I spent around 20 hours just to make buttons work and display song and artist info on LCD display and another 2-3 hours for little script which contacts my website with "curl" requests when playing a few choosen radio stations, so I can scrobble to last.fm from that radio stations. This would take maybe 2-3 hours in total with Java. Or maybe I should consider using PHP since I have some knowledge and it's already there and supported.
