"Please don't worry about 'wear' using the baseplate removal method – I'd be infinitely more worried about the fragility of the USB connection; and every time you reinsert the SD card you keep the terminals clean!""

"My experience with a range of pro and semi-pro cameras is that the camera usb connector port is their weak point, and tends to fall to pieces with repeated use. I have never used the usb connector on the M8 for that reason. Just take the card out and use a card reader."
"I never plug my camera directly into my computer. I'd much rather destroy a flash memory card than my camera. The USB port is also a 5 volt power supply and if not turned off with the icon for USB removal in the system tray, when you pull the USB cable, you can generate a spark or surge that may feed back into your camera.
More and more camera manufacturers are starting to address this in their manual.
"I ruined 3 thumb drives before it dawned on me that I was not buying bad thumb drives, so I explored the reason for the problem.
I rarely plug expensive devices into USB ports, AND NEVER INTO THE TYPES OF HUBS THAT HAVE THEIR OWN POWER ADAPTOR PLUGGED INTO THE WALL. Thats worse yet.
Even when I use a card reader, I disengage the USB port before pulling the device. On a PC there is an icon in the tray that looks like a PC card with a green arrow over it. Left click that icon and turn off the device in question. If you turn off the wrong device, like an external backup drive, you will have to disconnect and reconnect the device to turn the port back on.
Small detail to save your $5000 camera???
Just in case you wonder about this post, I have been making the bulk of my living for the last 16 years building, servicing and setting up PC's in single and networked environments. I also teach computer and digital photo classes and the info in this post is one of the fundamental basic in my presentations.""

En résumé USB -> 5 volt -> danger pour le M8 + si batterie faible pour les images.
