Hello Sl!derman49 and welcome to the forum!
Can you, please share more information regarding the issue that you have? I would be thankful if you describe with more details the PC configuration that you connect your WD My Passport Ultra to.
Here is a link to our official web site that you could use to download our diagnostic tool WD Data LifeGuard Diagnostics: http://products.wdc.com/support/kb.ashx?id=MCP2zJ
Please, run the extended test and come back with a printscreen of the results. Beware to remove any personal infromation on that screen.
Have you checked the USB cable that you use to connect the WD My Passport to the PC? If not, try it and if you have another USB cable to use for the connection, you could use it.
Hope I gave you idea. Have a great weekend!
