On a daily basis, I use a 1TB Seagate GoFlex external HDD that was originally a USB 3.0 interface until I bought the Thunderbolt sled (replacing the USB 3.0 interface) for things like Time Machine backups, photo management in Aperture and the like. Last night, I was on my Late 2011 15in Macbook Pro running a Time Machine backup and working in Aperture via Thunderbolt while charging the laptop when suddenly the drive was improperly ejected and the LED on the Seagate shut off as if no connection was made. I unplugged the Thunderbolt connections and tried again and the Seagate LED remained off and no drives showed up in Disk Utility. So I tried taking that Seagate and Thunderbolt cable and used it on another Mac, everything worked properly and as expected. So to further drive home the theory that maybe the Thunderbolt port on the laptop was bad, I tried using another Thunderbolt drive/cable on the Macbook Pro and sure enough, nothing happened. To me, this sounds like a bad port.

 

The reason for this post is that I've not yet seen anything on the interwebz regarding Thunderbolt port failures aside from a few estranged "display issues" via Thunderbolt. Has anyone else heard of this kind of thing happening? I find it a bit odd that with modern technology that tends to prevent overheating issues, this was able to happen. It almost seems like maybe a piece of solder broke off or something? Any thoughts?

    Have you rebooted the system? Have you tried a SMC and PRAM reset?

     

    If not do all three of those things.

     

    If you still have a problem hopefully you have Applecare as if you don't the fix will be expensive. You will need to have the logic board changed to fix a bad, broken, TB port.
