Buffalo HD-LCU3 Series Model Number: BUFFALO HD-LC2.0U3-BKD Recording Capacity: 2TB I purchased this as an external hard drive for my TV and connected it, but I rarely used it, so I disconnected it several years ago. I reconnected it to the TV and tested its operation for this listing, and it was able to record without any problems. It has been formatted and initialized. It supports USB 3.0, so it can operate at high speeds. Included accessories are a USB cable (1m) and an AC adapter. Please understand that this is a used item stored at home. Thank you.
