Having problems with your PC Laptops ?


Answers :

Most probably your laptop's power output on the USB socket is below specifications, or is exactly fulfilling the USB specfications and not a fraction more...
The USB socket should be able to deliver 500mA current at 5 Volts. Often external hard drives need a bit more during spin-up, and if the computer is unable to deliver this increased current for a second or two, then the drive won't start.
Solution 1: Try every USB socket you have available on your laptop - sometimes there's one that delivers just enough current to allow a HDD to start.
Solution 2: Buy a powered USB hub (a hub with it's own power adaptor) - these can deliver enough current to run the HDD. However, you lose your mobility, because you need mains power to feed the hub.
Solution 3: If you need mobility, return your WD, go with your laptop to a shop, check and purchase the drive that will prove to work with your machine. Or invest in a big Flash pendrive...
I have had the same problem with laptops and USB drives. The external drive simply is not getting enough power.

The two solutions that seem to work are:

1) External power adapter for the USB Drive. Many external USB drives have a micro power plug next to or near the USB plug. A 5 Volt adapter (which plugs into the wall OR one that plugs into your cigarette lighter plug in a car) will cure this problem.

2) Some external USB drives come with a plug which has (2) USB plugs which plug into your laptop (laptops typically limit the power for each USB port) and one plug on the other end for your USB drive.
