This is a used WD 1TB My Passport for Mac Portable External Hard Drive, in great condition. See the image from CrystalDiskInfo about the usage health stats: less than 2100 Power On hours! Where else are you going to get a guarantee on the condition of a used hard drive? Cosmetically in good condition too, the original plastic cover was never removed. Comes with the open box and of course the USB adapter cable. The device supports hardware encryption and works on Windows as well as Mac, see images. I used it to securely back up and access files between operating systems. I removed the password, so the drive is ready for its new owner. To add a new password, you need to use the WD Security program from Western Digital, which is free to download.
