I am running Mac OS X El Capitan 10.11.6. My 2TB Samsung T3 only shows 250GB Capacity. I have installed the activation software from: http://www.samsung.com/semiconductor/minisite/ssd/download/portable.html

I have formatted the drive using all available options under Disk Utility.

For an $800.00 hard drive that only has 1/8th of it's advertised capacity, this has turned out to be an enormous waste of money.

    Can you add screenshots of Disk Utility with the physical disk selected and with the partition selected? Also the output from diskutil list would also be useful

  • The activation software is if you want encryption. In addition to grgarsides request, also tripple check your packaging because Samsung does in fact make a 250GB model per their [specs(samsung.com/semiconductor/minisite/ssd/downloads/document/…)

I spoke with Samsung today support today: They said I had been sold a "Tampered Model". Amazon.com did honor the request to return the item even though it was well outside the 30 day window for returns.
