Recently I was using BB with the external HD and I got a warning about a USB Drive being disconnected because it did not have enough power. Then I rebooted and was able to begin working again.

Then again it happened yesterday , only this time my computer begins booting up and automatically shuts down. The HD is not attached at this time.

I have taken the MBPro for repair. I am a bit disappointed with this.

Is there a proper way to use the external drive , perhaps with a USB hub for better power?

BTW, I am not sure that it was the fault of the MB Pro. It seems that a couple times the USB cable was jiggled slightly causing the unit to lose power briefly.

Anybody got any suggestions about the best/ safest way to use the HD USB approach?

Thanks Jeff
