(adsbygoogle = window.adsbygoogle || []).push({}); I installed a new hard drive in my ps3. But I didn't sync my offline trophies. What will happen if I put in my old hard drive IN, sync them, then put back in my new one. Will I lose all my content like music, videos and pictures?

You can go back to the account you got the trophies on and do the sync for trophies but yes you will lose all the data you should just back up your ps3 before switching harddrives.

Thanks.. I'll just back up the stuff.

Yeah, back up the drives. You can't swap HD's without having the PS3 format the one you just put in.
