External USB hard disk not detected

Many external hard disks fail to get detected on some systems, whether they run Windows xp, windows vista or even linux.
The reason for this problem is the USB ports. Many USB ports are not directly connected to the motherboard, they use some internal hubs to connect to the cabinet of the PC.
The solution to this problem is to connect the external hard disk to a different USB port,preferably USB ports in the back of the CPU.
The drives fail to detect because they are not getting enough power from certain USB ports, connecting the external hard disk to the rear end of the CPU will solve the problem.
The fix mentioned was tested several times, and it works with all external hard disks.
