If you used (right-click → Format), it cannot format a drive larger than 32GB to FAT32. You need a third-party tool. Furthermore, Windows’ default formatter sometimes creates a non-standard FAT32 implementation that the PS2 rejects.

Type select disk X (replace with your USB’s number). Be extremely careful to select the correct disk. Type clean (this erases the drive). Type convert mbr and press Enter.
