I have a canon camera that used to shut down everytime I insert a certain SD card in it, but once I inserted another SD card, it worked normally, I took pictures with it on a 32 gb samsung new card, but I sometimes had "Cannot playback image" when trying to see the taken pics on the cam, I was told that it could just be that because it's a micro card and that i'd be able to see them on the laptop, but when i inserted it in the PC, it was totally empty, I'm doubting that a virus was on the camera that caused this, is there any way I can get back those photos ??!
