Instructions
Insert the pen drive into a computer's USB port. Click the "X" button on the auto-run window that comes up to dismiss it.
Click the "Computer" option on the desktop or click the "Folder" icon on the taskbar to show a list of all installed drives on the computer.
Right-click the pen drive icon and click "Format" on the contextual menu that comes up.
Click "File system" and click "FAT32" as the type of file system for the pen drive. This is the only non-proprietary format the PS2 can read.
Click the box next to "Quick Format" to enable it.
Click "Start" at the bottom of the "Format" menu to format the pen drive into a FAT32 pen drive.
Pull the drive out of the computer and insert it into the PS2's USB port on the front of the machine. The pen drive can now be used with games that accept this type of memory format, like "SOCOM 3."
