I need HELP retrieving pictures from my WD My Book Essential

I am trying to retrieve pictures from My Book Essential, I have multiple GB’s stored on the WD device but when it retrieves to the folder I have selected on my computer, there are no pictures transferred.  Please help, I am getting a sick feeling that my pictures are lost.  I bought this device specifically because I was told it was a trustworthy device to do such things.  Thank you for any assistance.

Hi there, first things first, how did you do the backup?

Did you do it manually? Did you use a software? If so, what software?

The drive itself will not copy your data on its own, a software (Either the one that may come with it or another one) is the one doing the job…

More details will allow to narrow down the problem.
