Thank you for viewing. This was a backup drive for a video storage hard drive, so it has very little usage time. - Brand: SEAGATE - Model: Expansion Portable Drive - Storage Capacity: 2TB - Interface: USB 3.0 - Color: Black - Included: USB 3.0 cable only (no box or manual) - Usage Time: 362 hours (at the end of formatting before listing) I believe it works without any problems. Instant purchase is OK. I will ship it on the same day of purchase if possible, or at the latest, the next day. As it is a small but precision instrument, I will pack it securely and ship it via Yu-Packet Plus. Thank you.
