So, lately my PSP has worked great but like a day or 2 ago my 8 gb memory stick got corrupted. I tried to format it in the psp's system settings but it just says ''Format failed. (80220087)''. When i put my usb cable in and tried to delete AND format it but it says something like ''could not format'' or ''file cannot be deleted''... I have googled it a few times and tried like everything but nothing works! So can someone please help me? It VERY annoying and i don't want to go back to my 2 gb pro duo... Edit: Ok, so now i found out the card write protected itself, and found the corrupted files...
