If it is the card, what brand/model? I use only Samsung and Sandisk because they always work despite my rough treatment. No problems from static or from sitting on the cards or accidentally using them as a coaster for my coffee mug.
Most of the other brands do not make their product. What you get with some brands is whatever they purchased cheap that week from an unknown factory.
The next problem I found was using the NOOBS card supplied in a kit. NOOBS screwed up something when it was supposed to reallocate the Ext4 partition and switch to Raspbian. After that I used only straight Raspbian downloads and never had problems.
Some USB hub/cables provided too little power and corrupted Raspbian partition. The recommended power supplies always work. My USB 3 hub with the 4 amp power supply, combined with short USB cables, always works.
