4TB Thunderbolt drive not mounting

[pittsure]

4T Gtech thunderbolt will not mount to either my MacPro nor to my MacBookPro. Using a brand new TB cable and just bought the drive from B&H. Is this a common occurrence?

Hi,

Thanks for your post. Thunderbolt drives will only work on computers that have a Thunderbolt port. The MacPro does not have Thunderbolt at this time, and the MacbookPro has only had it for the last year and a half. The display port uses the same connector, but will not work as Thunderbolt connection. Please let me know if you have any questions.

Regards,
