Thunderbolt freezes my Macbook Pro after connecting external HDD

i reset my PRAM when my mac start again and i connected to that thunderbolt drive after few minutes it freezes not responding any apps. that time i have to keep pressing power button to power off mac pc while that thunderbolt drive is working fine in other mac

Mac Pro 2013

3.5 Ghz 6 core intel Xeon E5

3 gb Graphics

I have similar problem with a macbook pro 15" retina (2013 spring) and 10.9

I have the same disk and sometimes, when connecting it does not shows up, but I don't get a system freeze. Instead I get the system freeze sometimes connecting to the thunderbolt either an external video (Apple video) or the ethernet to thunderbolt adapter and I have to force a shutdown. This always soon after a wake from sleep.

Not many with this problem?

Is it a faulty hardware?

Thanks,

Luca

Same problem here... MacBook Pro Retina, 13-inch, Early 2013 running 10.8.5

I connect my Lacie rugged 1TB via thunderbolt and my macbook pro crashes instantly. Does not happen every time - sometimes it connects without a problem. I happen to have been using both USB ports at the time of crash - I'm not sure if it has anything to do with that?

Very annoying.. computers less than a year old shouldn't be crashing for no reason!

Instead I solved mine with a PRAM zap. No more thunderbolt freeze. Use ALT+CMD+P+R on startup to zap the PRAM. I found the solution on another thread just soon after the post. Now is more than a month and no more freezes.

Ive had the same problem with my MBP Retina 15" late 2013. My screen just freezed and the my MBP just restarted and showed me the screen wher it say's your computer shut down because bla bla bla...

Zapping my PRAM worked for me so far, but i think that i wont be using my hard drive anytime soon...

Thanks dude it worked for me so far!

Same problem, using 10.9.2. Hangs everytime it wakes from sleep with an external monitor connected to the thunderbolt port. Maybe with a DVI to VGA adapter...

Thanks for your advice. I'll try the PRAM reset.

I got the same issue with a macbook pro retina end 2013 running 10.9.3.The LaCie drive is connected in thunderbolt on the Apple display .

I have applied the PRAM reset, so far so good....

This RIDICULOUS issue has been going on for me for months. Resetting PRAM has made no difference. Since I'm still under the warranty, I took it in and they replaced my logic board, display assembly, and two other internal connector parts...all for nothing. Still now, EVERY TIME a Mini Displayport to DVI cable is connected, it runs fine on both displays for 5 seconds then crashes, requiring a restart every time. I am considering wiping everything I have and seeing if a clean install will make a difference, but I have little hope that it will. I have no idea how I will ever fix this, as replacement of key components of my computer has still done nothing to alleviate the problem!

You know what, I just figured out a big part of my issue. This only happens when MagSafe power is connected. When I connect my MacBook to power, it is unusable, but when I disconnect the power, it works again. Is any of your guys' problems related to the power cord's presence?
