I have seen reports scattered around the internet and across different phones related to what I just experienced.
I discovered tonight upon opening Gallery on Fission 2.4.3 that practically all of my images and videos had somehow been deleted from my SD card. In my camera folder, where 250 images had been, 6 now were. I have no explanation for this, but used recovery software to get most back.
Does anyone have any insight into this? I know about the need to unmount properly, etc., but a data corruption from improperly disconnecting a flash drive should destroy random data. This deletion was only images and videos.
