1. USB-HUB is a device that provides extended communication. If the Hub can drive 2.5 inch shift without external power supply.
The hard disk mainly depends on the power supply capability of the computer expansion port!

3, without external power supply: a computer USB port provides a current of about 500MA, can only barely use a 2.5-inch mobile hard disk, and then consume a part of the USB-Hub, is not enough for ordinary 2.5-inch mobile hard disk of.
4, many compatible machine chassis front USB port, due to more than one transfer, coupled with wire and other material problems, the power supply capability is even worse; very easy to cause the mobile hard disk can not be used or even lost data, damage the hard disk;
5. If your mobile hard disk makes a "beep" sound, it is caused by insufficient power supply; for your mobile hard disk, it is recommended to connect the USB-Hub to the integrated USB port on the back of the chassis to ensure better. Contact and power supply [2]
