As a photographer, I have to deal with losing data from time to time. I usually back up my SD cards right after a shoot so that I do not have to worry about them. I never delete images until I have them backed up in two different locations. In my early years, I had to use a western digital data recovery service on more than one occasion. I remember the tears I cried the first time I lost a client’s images. I am so thankful that there are recovery services out there for people like me. They saved me more than once.
