Did you try with a different USB cable?

By the way, from the screenshot above, it looks like WD Diagnostics tool failed to retrieve hard disk model number as well.

Yes tried with a new cable same result.

Hi chimera201,
I'm sorry you are facing such issues with the WD drive. This error means that a device I/O control command during the test has failed. It may be due to a media or write/read error or defective connection.
If the error persists after re-seating the cable connections, I'd suggest trying the drive in another USB port or another computer altogether. If that doesn't help, I strongly recommend contacting our tech support on the following link:
