I have a USB 3 External hard drive. The problem is that the USB 3 cable I have is too short. Can I plug the USB 3.0 cable into a USB 2.0 Male to USB 2.0 Female cable ? I'm at work so Just though I'd ask you guys for an opinion.

According to this, section 5 talks about how USB 3 and USB 2 cables are different.

It would have made sense for the design to be backwards compatible but that doesn't mean it will be. I think it will be safe to try. If the drive was to get enough power to operate, I'd expect it to work at USB 2 speeds.

Give it a shot and let us know the results!

Thanks for posting your results Sl4y3r. Looks like the speeds dropped to SATA 2 for your extension cable.
