Record Box Data Base

I moved my database to my external hard disk so i can work to 2 machines!

In my pc at my studio, (preparing traks etc) and in my laptop for djing in clubs!

But when i finished some work in my studio i place hard disk in laptop and tracks was analysed in mylaptop but when i linked them through ethernet cable to my xdj rx the wave form doesn't appear! And it was asking for record box analyse!

I had to make analyse again from my laptop.. And i'm thinking not do the option to move my database again because i don't wont again to have the same problem!

Any solution??ideas??
