2TB recording hard drive with excellent quietness and heat dissipation. - Brand: I-O DATA - Model: Recording Hard Drive - Capacity: 2TB - Features: Quietness, heat dissipation, tested for long-term continuous recording Thank you for viewing. I received this from a friend who accidentally purchased it, but my TV is not compatible, so I am selling it. I took it out of the box and attached the cord, but the item itself is unused. There are no major noticeable scratches on the main unit. It is a used item, so please forgive any oversights. I think it's an external HDD in beautiful condition. I am also listing it on other sites, so please leave a comment before purchasing.
