Password protected, 20TB Seagate Expansion external hard drive. Recently purchased as an excellent refurbished unit. I used it a couple of times, but decided I needed a 28TB Seagate Expansion hard drive, so I purchased the 28TB hard drive and no longer need this 20TB Seagate Expansion hard rive. It comes password protected. Any questions, please write, and I'll do my best to answer them, but I'm not really a high tech type person. Although it was an excellent refurbished unit when purchased, I'm listing this drive as used since I used it a couple of times. While it is used, it is in very good condition, and includes the cable and the USB cord. Thanks!! FREE SHIPPING!!!
