So if I understand your question correctly

by OH Smeg In reply to Troubleshooting - Externa ...

When you plug your External WD Drive into a USB Port of your running computer the LED light on the enclosure goes out and there is nothing working. Is that correct?

If it is look at the Power Adapter for a possible problem and if that is fine the Electronics inside the case between the USB Lead and the HDD has failed.

The only resolution available here is to return the complete enclosure to WD for Repair/Replacement.

If I have misunderstood your question please post back with your description of what is happening.

Check the AC power adapter

by nepenthe0 In reply to Troubleshooting - Externa ...

Western Digital has an excellent reputation for its hard drives. However, the power adapters can fail.

If you have a digital voltmeter, check the adapter output. My guess is that you will find zero voltage, indicative of a failed power adapter.

If the hard drive is under warranty, you should have no difficulty with replacement. If not under warranty, I recommend purchasing a replacement adapter from Western Digital, rather than a generic type which may overload and damage the hard drive motor.
