[QUOTE="PaulR, post: 1046520, member: 176256"] I can easily see that it would be the case that an external hard disc drive would need an extra power source. From memory USB2 ports have a maximum current supply of 500mA (USB3 can supply more). From practical experience I know that just connecting portable hard drives to computers without the external power supply sometimes works and sometimes doesn't. In fact many of the external hard discs have a special double headed USB lead so that it can plug into two USB ports and get the extra current that way. [/QUOTE]
