I bought a PSP 2001 on the cheap a little while ago. When I got it the seller said it would not read UMDs. The dude must have been a dumbass because it looked like he cleaned the lens with clorox or something. aka lens was melted. I ordered a replacement UMD drive off of ebay. It worked like 4 times, but then stopped reading them. It just sits on the loading icon, but never gives me an error.
So I got another UMD drive. It still does the same thing. Just tries to load the game forever with no errors. I eventually have to take the battery out to get it to cut off.

As a side note: When I turn it on with no UMD it does make gear moving sounds and acts like it would read the UMD.

Any help would be greatly appreciated.
