Does Your Apple ThunderBolt to Firewire Cable Disconnect?

I bought an Apple Thunderbolt to Firewire
Adapter a while back. I just got around to
using it and it disconnected while making
a Clone.

Is anyone else having this problem?

Ok, I have a MBAir w/SSD and an external
Sabio Enclosure that has USB/2.0, eSATA
and Two Firewire 800 ports. The Sabio holds
two Hard Drives. You can use the Sabio
without a power supply but it doesn't
usually work well that way. So its Power
Supply was attached.

I had been using USB to make ocasional Clones
from the Air to the Sabio and had no problems.
Since I recently bought an Apple TB to FW
Adapter I thought I'd use it on the Air to speed
up my Clones. I attached the TB to FW Adapter
plugged in a good Firewire cable. Attached Power
Supply and fired up CCC.

About 2/3rds into the Clone the Hard Drive disappeared
from my Desktop and I got the Improper Disconnect
Message. I thought I might have bumped the Air
since it was on the bed so I remounted the Sabio
erased the Partition and tried again. The Clone
was ejected again 2/3rds in. I tried a third time
and once again.......Improper Disconnect!

I've now successfully Cloned using the old tried
and true (SLOW) USB cable. The Apple TB to FW
Adapter wasn't hot to the touch. What gives? Is
anyone else having this same issue?

THANKS!!!

Could you describe how you're using your cable?

same here

I have the same problem -- I'm using a thunderbolt to firewire cable to connect a time machine disk. Time machine is unusable -- it disconnects constantly. I then used a USB 2.0 cable to connect to exactly the same disk (it has both USB and firewire 800 ports) and it's working flawlessly.

I'm going to return the cable, I think.

Mine is solid.

Make sure you use quality cables.

Are you powering from FW or does it have its own power brick.

Can you try the drive on another machine, perhaps the drive is starting to have issues, one of the first signs can be drop outs.

I'm using the 800 cable that came with my G-Drive. It has its own power brick and it's pretty much new. Worked all of the time with my '07 MBP until I got my Retina. Also, it works fine on my Mac Pro.

Any reason it would be my thunderbolt to FW800?

Yes, yes, yes! I have this adapter and it keeps disconnecting. Sometimes it just does it without any apparent trigger, and other times the same happens if I touch the adapter in any way - even when extremely slightly. Frustrating :( I know it could be the port on my new 15 MBP Retina, but both TB ports behave the same.

You're not alone.

AN UPDATE:

Yesterday I ran a software update that also seemed to have a 'sub-update' promising to improve Thunderbolt stability, or something along those lines. AND IT WORKED - so far so good, no disconnections at all. :D
