I bought a My Passport a few years ago to remove data from my PC. I then got a mac.
A friend formatted the WD Passport external hard drive and removed my files from it. It is formatted NTFS.
So I went to the instruction page on WD as and its give instruction on how to format tp exFAT or FAT32.
However when in disk utilities its does not give me the option too partition (this button is there but i am not able to click on it).
It also says I have no permission on the drive but i am guessing this is because the format is incorrect.
How do I allow it to be partitioned??
I have a Macbook pro from 2013 and am using El Capitan
Any help much appreciated
