This is an external hard drive from Buffalo. I bought it for TV recording, but unfortunately, my TV wasn't compatible with the product's specifications, so I'm reluctantly selling it. It's practically unused, as I only tested it once by connecting it to a TV. It's in excellent condition, having only been used for the connection test, but it has been opened. Please check the model number on the manufacturer's website to confirm compatibility with your devices (TV or PC) before purchasing. Model Number: HD-AD6U3 Manufacturer: BUFFALO Included items: Main unit, AC adapter, USB cable, Instruction manual
