1 TB My Book Essential USB 3 is failing

Hi,

My recommendation, is to get all the information out of the drive. It could be a sector issue.

When you try to run the test, what is the error that you are getting?

If you are able to get the information out of the drive run the WD DLG Tool to write zeros on the drive as this will attent to eliminate any bad sectors.
