To drag and drop you must have the manually manage music box checked.
Also, iphone will sync or manually manage with one and only one computer at a time. Syncing or manually managing with another will erase the current content from the iphone.

I posted something similar. My older MBP had to have the RAM stick replaced and in the process the HD was wiped clean. I have used my back-up on an external HD to put everything back. However, now I cannot get my iPhone4 to sync the way it did in the past.
