BUFFALO This is a set of a Buffalo TV recording recorder (built-in 1.0TB) and a Buffalo external hard drive (2TB). It has been used very little and stored with the power off. Everything in the photos is included. I believe it can be used without any problems for both recording and playback. I have just performed the initial setup process to restore it to factory settings. It is a genuine product that has not been modified. Recommended for TV recording during the New Year's holidays. ＜TV Recording Recorder＞ DVR-1/1.0T BUFFALO HDD recorder with W tuner, 1TB Simultaneous recording of 2 programs Built-in 1TB HDD External HDD can be connected via USB. ＜External Hard Drive＞ HDD2TB HD-LS2.0TU2C 2TB with USB ～～～～～～～～～～～～～～～～～～～～～～～～～ Product Overview of Buffalo BUFFALO TV Digital Terrestrial Recorder HDD 1TB Built-in DVR-1/1.0T A simple recorder for comfortable use Even if the hard disk on the main unit becomes full, it's okay.
