Drive is not recognized by Data Lifeguard Diagnostics for Windows: If the drive is not recognized by Data Lifeguard Diagnostics, follow the instructions below to troubleshooting this issue:. Make sure that the drive is properly connected to the PC. If it is an internal drive make sure the SATA or PATA (EIDE) cable is securely attached to both the drive, and the controller card.
If it is an external try replacing the USB, FireWire, or eSata cable and rebooting the system. Make sure the drive is getting power. For internal drives, make sure that the power cable is properly connected to the drive, and that both a MOLEX (4-pin) and SATA-type power cables are not connected to your drive simultaneaously. For external Desktop drives, try plugging the power directly into a wall outlet (instead of a Universal Power Supply or power-strip). For portable external drives, try using a Power Booster Cable to supply extra power to the drive. Right-click on the program and select Run as Administrator. Try reinstalling the Data Lifeguard Diagnostics for Windows utility.
It is possible that the installation has become corrupted. If the drive is internal, make sure that the jumper settings are correct based on the diagram on the drives label.

It's best to consult a computer technician or vendor for further system testing.
If the drive still is not recognized, than it is most likely damaged and needs to be replaced. Please see for assistance with this process In case the answer did not answer your question, you can always visit the for help from WD users.
