Hello, We had accidental data deletion related to our device with WD MY CLOUD PR 4100 Model number, WUBP27230104 serial number that we bought on 27.02.2017. Although we attempt to contact all authorized services in Turkey we did not find counterparts that could help us. We were told to contact you by mail. We provide services in the areas of photography and video service, we would be very happy if you return immediately. Thanks in advance good work.
