Thank you for viewing! This is an external HDD for TV recording. Both the case and the contents 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 light. The included items are this recording HDD and one USB cable to connect to a TV or computer. The USB cable is approximately 45cm 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, Mitsubishi Electric, Pixela, etc. If you are unsure whether it can be used, 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 normally with CrystalDiskInfo's failure prediction information (S.M.A.R.T.). With 500GB, you can record about 60 hours of HD quality, depending on the TV and compression quality. If your TV supports dual-program recording, 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. This portable HDD is bus-powered, so an AC adapter is not required. You can also use it as an external HDD on a computer, but once it has been 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. This product is not subject to price reduction. Shipping is planned via Yu-Packet Post Mini, wrapped in bubble wrap.
