Thank you for viewing. This is a WD Elements 5TB external hard drive. I used it for data storage on a Mac. The original AC power adapter and USB cable are included, and the protective film on the exterior is still in place. Before listing, I erased the entire disk twice using Disk Utility, and there were no issues. It is currently formatted for Mac, but I can format it to exFAT for Windows if you prefer. I look forward to your purchase. The WD Elements with 5TB of storage offers fast data transfer via USB 3.0. - Brand: WD - Model Name: Elements - Storage Capacity: 5TB - Connectivity: USB 3.0 Search terms: 2TB 3TB 4TB 6TB 8TB
