BPM , Mediabase , two different computers

Hi guys,
I have a powerful desktop computer and i have a netbook .
I want to run all bpm calculation on my desktop computer and save all infos into the mediabase.
Here comes my problems, on my desktop , all my song files are in different drives letter compare to my netbook
eg : desktop - e:/mp3/songs.mp3
netbook - c:/mp3/songs.mp3
so , my question is , how do we "calibrate" the mediabase to recognise the songs instead of the file path? it shows all read when i load the saved mediabase form my desktop to my netbook because it can't find the files.
