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!!!
