Thank you for viewing. This is an external HDD for TV recording. Both the case and the contents are made by domestic manufacturers, so you can rest assured. HDD Case: Logitec HDD: Toshiba Size: Approximately 13cm x 8cm x 1.5cm Weight: Approximately 150g It is very compact and lightweight. The included items are this HDD for recording and one USB cable to connect to a TV or computer. The USB cable is approximately 50cm long. In addition to TV recording, it can be widely used as PS5/PS4 expansion storage and an external HDD for computers. Basically, this HDD can be used with current models (not discontinued) of TVs with recording functions. Sharp Aquos, Sony Bravia, Toshiba Regza, Panasonic Viera, LG Infinia, Hisense, etc. If you are unsure whether it can be used, I will check for you, so please let me know the manufacturer and model number before purchasing. 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 the TV and compression quality. If your TV supports recording two programs simultaneously, you can record two programs. Basically, it will be recognized just 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, so high-speed data transmission and reception are possible. It is a bus-powered type, so an AC adapter is not 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 it cannot be used for both. In the unlikely event of a failure or if you want a larger capacity, you can remove the HDD inside without tools, so you can replace it yourself. Shipping will be via Yu-Packet Post Mini, wrapped in bubble wrap and an envelope. Due to the nature of the product, we cannot respond to requests or questions received more than one week after delivery is completed. We are also selling other capacity HDDs and laptops!
