he said he was taking the umd drive out of the psp tho
oh and i had the same idea but i then thought after all the different mod i have done to many psp's i would try and create some that can be added and removed with ease for example making a removable umd drive that just slots in when i need it although this would be quite hard it is still possible, anyway another way would be to make it plug into the usb slot externally so that you can remove it if you want it inside permanently then ill try and figure some way of being able to plug in the umd drive externally and get back to you
thanks
