OWC keeps claiming this is a huge universal issue with all kinds of hard drive manufactures that use thunderbolt connection and 10.2.2

The discussion that took place here has proved OWC is right : this is an issue with various kinds of HD and 10.2.2 is « guilty » !

YYou mean 10.10.2, right; or are you talking about something else? Maybe OWC needs to write new drivers?

The problem is only the 10.10.2 , not ours Thunderbolt HDD. See and wait if a patch will be deployed by Apple.

yes I mean 10.10.2 - my bad.

OWC is digging deeper for my set up, they are very helpful and want to see this resolved. Hopefully we will know more this week.

These external Thunderbolt drives, like the LaCie d2 I'm having trouble with now, don't need any custom drivers to function. This drive causes a kernel panic when I power it off, with a vanilla OS X installation (no custom driver). Since 10.10.2 only.

Here's the kernel backtrace from the panic log:

As far as I can tell reading threads on a few forums this is happening to three drive box manufacturers, OWC, LaCie, and G-Tech. If it's happening to others or other system let Apple know in feedback.http://www.apple.com/feedback/

I have a new G Tech 4tb thunderbolt drive that works fine with my Mac Pro and 10.10.2, and yesterday I purchased a new Lacie portable 2tb thunderbolt/usb3.0 drive that works fine. My only issue is with the OWC set up.

You're having a problem with the setup, installing it? Well, there was something strange with the setup of two LaCie drives I bought from Apple. I had two already (3TB and one 6TB), bought from Amazon. Setup went fine with those. But the two drives from Apple had trouble with the setup (causing kernel panics). When I finally succeeded in finishing the setup and mounting them, they didn't work as expected. They had reading errors which were detected by Carbon Copy Cloner. So I sent them back. Then I bought another 6TB from a local shop and this one setup in a jiffy and worked fine as well (apart from the sleep and shut down problem of course). So, what is happening???

VVS8344 are your drives Thunderbolt o Thunderbolt 2? Maybe the OWC is Thunderbolt and the new G-Tech and LaCie you bought are Thunderbolt 2?

I don't even know if the kernel panic happens with both types of Thunderbolt connections or only with the first type of Thunderbolt.

Great diagnostic question!! No one from Apple or OWC asked that. I just checked and the g-tech and lacie are not thunderbolt 2 while the OWC set up is thunderbolt 2. So now I wonder if the issue with 10.10.2 only effect thunderbolt 2 drives? and if so what can I do to work around that?

No, sorry! I'm having the kernel panic problem with a Thunderbolt 1 iMac with a Thunderbolt 1 disk drive (LaCie d2 model # 9000303). But another Thunderbolt 1 drive (LaCie 2big model # 9000246) doesn't have the problem.

Got the same problem with my iMac27 2012, 10.10.2 and WD My Book Thunderbolt Duo 8TB!

Same here... Mac Pro 2014 10.10.2 and thunderbolt drives. 8Tb G-Tech and Seagate Thunderbolt (adapter) drives.

During sleep overnight it freezes and will not wake up. When I reboot I get the ejected drive failure warnings for all the drives. I have to close FCPX and Motion and Compressor, eject all three drives just to sleep. When I forget its a big mess. This is not acceptable.

I changed my LaCie d2 Thunderbolt 3TB with a new LaCie d2 Thunderbolt 2 3TB. No issue with the new one, always on OS X 10.10.2.

Has anyone tried the public beta of 10.10.3 to see if this bug has been addressed?
