PSP firmware 5 and the Memory Card Issue

 

Have you updated the Sony PSP firmware 5.0? Alright, there’s an issue in the 5.0 update related to the Memory Stick Pro Duo cards. When downloading the content from the Store to PSP with an 8 GB or 16 GB Memory Stick Duo media inserted, you may see a message appears saying that the media does not have sufficient free space, even if it is sufficient.

 

Sony has classified this into the "known problems" and is working to fix it. The 5.01 Update should be out soon...
