Trading in PSP ?

My PSP slims UMD drive broke, so I want to sell the psp to Gamestop. Whenever I turn my PSP on with a UMD in it, it makes a clicking noise and then says "Disc could not be read." Will Gamestop test any UMDs in my PSP that I want to sell? If so, will they still buy my semibroken PSP? BTW it still has the battery and charger.

does it still read from the memory card ok?
if so id take it off your hands

More than likely, they will check to see if the system works, which means they will test a UMD out. I know they will take broken items in, but I can't verify if they would take a PSP with a busted drive. Even if they did, the refurb fee would probably make it not worth your while to trade it to them. You'd be better off selling to someone.

Sell it to Joe or on ebay. You would still get more money selling it on ebay as-is than trading it in to gamestop.
