Reviews for Apple Thunderbolt to FireWire Adaptor

Drives mount when connected, then drop after 5 or 10 minutes. This has been tested on two different drives (one bus powered and one powered). Total frustration with this product.

I'm on my second TB/FW adapter. With the first, my G-Drives would randomly unmount themselves constantly, sometimes while I was actively using them. After exchanging the adapter, neither of my external drives will mount at all!

Both G-Drives worked flawlessly through a FW800/FW400 cable on my late-2006 iMac for years, and continue to work flawlessly through USB on my new 2012 iMac, but they're a couple of unresponsive bricks when connected through this useless adapter.

I've been working with an Apple Senior Advisor for several days trying to resolve this problem, but I honestly believe Apple just has a junk technology they haven't worked the bugs out of yet. Either it's firmware, something in ML, or the hardware in the adapter itself is faulty, but a lot of people are having the exact same problem.

Very disappointing!

This can provide only 7W to firewire devices. There are many, many devices that need more than this. You should absolutely check before buying to find out what your devices need in terms of power. Otherwise this is useless, as it is for me more than half the time.

I can't help but feel cheated and robbed by Apple..... they had no problems over the years selling me FW 400 and FW 800 devices yet this adapter only works with one of them. I can't even connect my older Apple iSight without now going out to find someone who sells a FW to FW adapter to go into Apple's Thunderbolt to FW adapter. pretty stupid if you ask me. Why didn't you include an adapter within the adapter if you're going to require it anyways?

Previously used firewire 400 on old mac. Bought a firewire 800 cable 9-4 pin and adapter.
New firewire cable worked in my daughters Mac Book Pro 2011. Imported video---so I know that part works.
I added the adapter for my retina Mac Book Pro 2012.. I does not recognize camcorder.
Either its the adapter or the imovie 11. Next I will try a different import program and see if it recognizes camcorder. I have so many old tapes to transfer!

Well dang... A brand new Macbook Pro Retina, new Photoshop, new Lightroom and I bought the 2 adapters recommended by Apple- Thunderbolt to Firewire 800, Firewire 800 to Firewire 400- to dump my 132 meg photographs onto my shiny new 16 GB Ram machine... Say What??
NO GO!!! Oweeee. I called apple tech support, the guy runs a few PRAM reset programs and then proceeds to tell me to bring my new computer into an Apple store, the nearest one being about 7 hours round trip.
Let me explain- the Thunderbolt to Firewire 800 adapter works great on my Lacie hard drives. The Firewire 800 to Firewire 400 works great on my older MacBook Pro Firewire 800 port to run the same hard drives. So I guess the adapters are fine.
So WHY Can't the combination work together to run a powered Firewire 400 drive???
I am irked as the Apple tech/sales guy who helped me put this computer together told me Apple had the solution when clearly it hasn't been sorted out yet.
As I said back up there- DANG!!

I have an external FireWire 400 drive that does not require a power supply when connected to either a FireWire 400 or 800 port (with 400 to 800 cable). When I try this Thunderbolt to FireWire adapter with a FireWire 800 to 400 cable, it does not work. Apple should either put this in the description, fix the issue or sell a Thunderbolt to FireWire 400 adapter.

Well basically... It doesn't work with iOmega eGO. Lights comes on but no connection. This is probably my 5th review ever in my life so this shows how frustrated I am. I want people to avoid buying a hd in hopes of having this $30+ disappointment free up a usb slot... I opt out from getting a USB 3.0 drive to save up on the limited USB but that plan failed...

Other people are having the same experience with HD that doesnt have a dedicated power supply.
