new 70D error on PC disconnect.
Got my 70D a few days ago and noticed some problem.
had experienced it three times.I connect to PC and use drag and drop to move the images/videos to my harddrive.
after that I pull the USB cable off the camera. but the camera get stuck on the "pc connected" mode (the LCD screen still shows it as connected to PC) and the top LCD have a "err" message.
Even when I move the power switch to "off" it still stays on in that error/pc connected state. and I have to remove the battery to power off and then power on.
Camera seems fine after that and card is not corrupted or anything. Anyone experienced this on their 70D?
