This item is for the replacement and repair of the Panasonic DIGA BRX-4000's internal HDD. Made by Western Digital. Perfect for repairs or as a backup in case of HDD failure. ※ This item is an HDD containing the recorder's "system binary," but it is a hidden file and cannot be viewed on a computer. Please be aware of this. ※ The recorder body in the fifth photo is for reference only and is not included. ※ This item has been successfully installed and booted by the seller, but as it is an older item, it is being sold as completely junk to avoid any issues. ※ The HDD's performance is normal, as shown in the fourth photo. ※ In rare cases where this item does not boot, clone this item to another HDD and install that HDD. We are unable to provide support for the replacement or repair. Please research information online and use it at your own discretion. # DIGA Item number 74
