Hi!

I have a never opened (the seal is still on the box) 2TB hard drive that works well on either Mac or Windows.

It's the exact one advertised here: https://www.amazon.com/Seagate-Backup-Portable-External-STDR2000100/dp/B00FRHTSK4/ref=sr_1_2?ie=UTF8&qid=1520725570&sr=8-2&keywords=backup+plus+slim

I purchased it for $65 on Amazon, and I'm willing to sell it for $50 here. I'm on campus all day, and can meet you where ever is convenient for you on campus. This is a great chance to get a hard drive cheaper than anywhere else (the book store on campus charges even more than Amazon), in as convenient a way as possible.

Let me know if you're interested!
