Bests & Worsts Reviews from Amazon

I have several LaCie Rugged drives with different connection ports and use them for travel. All of the previous ones I've owned have worked well, so I was surprised when I received this one and it was a lemon. The reason I purchased it is that the new MacBook Pro only has USB-C ports, so this seemed like a reasonable deal. I have no idea why, but when it mounts on to my MacBook Pro or to my big Mac Pro, it shows that it only has 411MB. I tried following the LaCie setup, as well as formatting with the Mac Disk Utility and it still showed only around 400MB. I tried copying over 2TB of data onto the drive and it produced an error message saying there wasn't enough room on the disk, so it's definitely a problem with the drive. I tried using it in both El Cap as well as High Sierra to no avail. I tried 2 of these drives and they both had the same problem. All of my older drives mount with no issues, so I have no idea why this doesn't work.
