Not able to Write on WD My Passport 1 TB


I’ve had the passport for a while now (less than a year). I’ve been manually backing files to it. The drive is formatted with OS X journaled. Last week I reinstalled OS X Mountain Lion, plugged the drive and I can see the files, but I am not able to write any files to it. In Disck utility shows it as:

Disk Description :WD My Passport 07A8 Media

Write Status :Read/Write

I am not able to change the read/write status of the drive from the info window. What else can I do to enable write on the drive?

Thank you.

Hi, have you tried clicking on the Disk Utility repair option? 

How to test a drive for defects or problems on a Mac 

Unfortunately these options are grayed out.

Thank you
