Thank you for viewing! This is an external HDD for TV recording. Both the case and the internal components are made by Japanese manufacturers, so you can rest assured. HDD Case: Logitec HDD: Toshiba Size: Approximately 13cm x 8cm x 1.5cm Weight: Approximately 150g It's very compact and lightweight. Included are the HDD for recording and one USB cable to connect to your TV or computer. The USB cable is approximately 50cm long. In addition to TV recording, it can be widely used as an external HDD for PS5/PS4 expansion storage and for computers. Basically, this HDD can be used with current model TVs (not discontinued) that have a recording function. Examples include Sharp Aquos, Sony Bravia, Toshiba Regza, Panasonic Viera, LG Infinia, and Hisense. If you are unsure whether it is compatible, please let me know the manufacturer and model number before purchasing, and I will check for you. The case is new! The 2.5-inch HDD inside is a used item that has been confirmed to be working properly with CrystalDiskInfo. 1TB = 1000GB. With this capacity, you can record approximately 125 hours of HD quality video, depending on your TV and compression settings. If your TV supports recording two programs simultaneously, you can record two programs. Basically, it will be recognized simply by plugging it into the TV's USB port. If a message like "Please format" appears, follow the instructions. It supports the latest USB 3.2 Gen 1 connection, allowing for high-speed data transfer. It is a bus-powered type, so no AC adapter is required. It can also be used as an external HDD for computers, but once formatted for TV recording, it cannot be recognized by a computer, so they cannot be used interchangeably. In the unlikely event of a failure or if you want a larger capacity, you can remove the internal HDD without tools, so you can replace it yourself. Shipping will be via Yu-Packet Post Mini, wrapped in bubble wrap and an envelope.
