2. Generally, 2.5 “mobile hard disk needs to be powered by a computer or Hub, and 3.5” mobile hard disk needs to be equipped with a special power supply with high power. Please do not directly connect this kind of device;
3, do not connect to the external power supply: a computer USB port to provide the current of about 500MA, can only barely enough for a 2.5 inch mobile hard disk, and then through the USB-hub consumption part, is not enough for ordinary 2.5 inch mobile hard disk
4, many compatible machine chassis front USB port, due to more than one transfer, coupled with wire and other material problems, power supply ability is more bad, very easy to cause mobile hard disk can not be used or even lost data damage hard disk,
