This is a 4TB I-O DATA external hard drive for TV recording. The TV I purchased at the time didn't support 4TB, so I never used it and it's been stored in a closet. It has been cleaned, tested, and formatted. - Brand: I-O DATA - Model: 4TB HDD - Features: TV recording, compatible with PC - Accessories: AC adapter, instruction manual, cable - Other: All items shown in the images are included. Available for immediate purchase. Thank you for looking.
