I have a 640GB Transcend USB 2.0 hard drive that sometimes won't be detected and keeps beeping. Unplugging and re-plugging in the cable always fixes this, but it's annoying to have to keep unplugging and re-plugging, not to mention probably not good for the drive.
I've gone to device manager -> USB controllers -> right click, scan for hardware changes, but it doesn't help.
I've got a cable with two USB ends, and I've plugged both into USB 2.0 ports at the back of my desktop computer. I do have USB 3.0 ports - would it be a good idea to plug both cable ends into USB 3.0 ports for additional power, or is this a bad idea? Should I plug one into USB 3.0 and one into 2.0?
