Samsung Galaxy S II :: Usb Media Scanning At 0%?

I woke up this morning and the media scan was running at 0%, first of all i didnt think much of it so i just left it. A few hours later I heard my phone was dying so I went to put it on charge and noticed that the media scan was still running. so i turned it off, waited a few mins then turned it back on, just in case it needed a bit of a kick up the backside. Once I had turned it back on I just left it on charge while I went to do things. went back to it a little while later and it hardly charged at all and the media scan was still at 0%. I uninstalled a few apps - nothing changed, tried connecting to kies via usb and nothing as it was still scanning. The phone itself is is very hot at the top behind the camera, it's not charging properly and I havent been able to back anything up - I just hope everything is stored on my sdcard.
