I recentley lent my brand new WD Passport Ultra 1TB external hard drive to a friend of mine. When I got it back I wasn't able to access any of my files, and now not all of the partitions appear when I plug it in.
My first approach was to open the disk in disk utilities and run a repair: the response was that it couldnt repair and I should copy those files I could access, delete the whole thing and start over.
Then I tried to run a diagnostic in the WD utilities. The hard drive is detected but nothing happens when I try to do the diagnostics.
The problem is that we are talking about around 300GB of videos, series and pictures and I would really like to keep those files.
I've read that there are some types of software that can retrieve my files but I'm not really sure which one of them to choose. All help appreciated.
