Black external hard drive with USB 2.0 connection, HD-CB1.OTU2 model. 1TB. As shown in photos 5 and 6, the base of the adapter is deformed due to heat. I was using it for computer backups until yesterday, and it is usable when connected to the main unit. It can also be used for TV recording. Due to the above reasons, it is being sold as junk at a low price, but we would appreciate it if you could consider it with no claims and no returns after understanding the contents. - Model name: HD-CB1.OTU2 - Connection port: USB 2.0 - Color: Black - Accessories: AC adapter, USB cable Thank you for viewing.
