My 60gb players are full (less than 1gb left). I'm going to remove one of the 30gb drives in each player and replace it with a 60gb drive to make a total of 90gb's. I normally make sync's to my PC via WsFTP so I have exact backup's of Drive0 and Drive1 in my player. Is there any other folders that I need to backup before my upgrade? After the upgrade I plan on just doing a reverse sync from my PC to my Empeg to restore the music and playlist's. This will work, right?
