- WD My Passport 0748 Media - The disk you inserted was not readable by this computer

Can someone please help me.

My Passport is a couple years old suddenly stopped working in my macbook pro and all devices with a USB port.

It appears everything has been erased… I have plugged my sisters WD external passport in and it works fine. My macbook is OS X El Capitan. Version 10.11.5 (15F34)

I have used the Disk Utility and have tried repairing. It says that the SMART is not supported.

Someone please help me as this was the only back up I had of everything.


Hello, I would recommend you to connect the drive to a Windows computer and run the DLG, this software should recognize the drive and test and see if it has any damage.

If the drive shows sign of failure, you can contact a data recovery company and they should be able to get the information out.

You can also contact tech support and see if they have other solutions that they can provide.
