Power Surge on Hub port Solution for External Hard Disk

If you have recently bought a new External Hard drive which requires no power adapter you might encounter this error. This is most common for 3.5″ Passport drives and other similar products manufactured for single USB power supply support. Most motherboards built with on board USB power has variable power supply assigned to them. The USB 2.0 ports and USB 1.1 or the latest USB 3.0 have different level of power amplification assigned to them. So the device which you are trying to connect might get lesser voltage.

Connecting with on board USB ports might solve this problem in most of the cases. The front USB ports are weaker and should be used only with Pen-drives or other devices which require less or no power at all.
