Accidentally restored/deleted my WD external drive. How to recover it?

Hello all,
I was trying to create a restore of my MacBook Pro on my WD external drive. I found some steps online and decided to follow up these steps. I went to “recovery mode >> Disk Utility >> Restore” which turned out to be a restore of my WD external drive. Now, I seem to have lost all my files that used to my WD external drive. Is there any way to recover my files?
Thanks a lot in advance for your answers.
Best,
Martin
