Wait I just burned an image 15 minutes ago and you even verified that the burn was good. Now you can not find the card.
What the heck....
Plug in original 16gb SD card that came with RPI-3. Computer says there is a 512kb card here. Do you want me to format it. Humm. What the heck again....
Plug in 64 gb SD card that was in it when I ran bad pixel code. Computer beeps a lot. Install driver, uninstall driver, install driver, uninstall driver, install driver, uninstall driver. Humm. This seems like a serious problem.. Maybe my SD read/writer is having an issue. Maybe it is the RPI-3.
Lets remove RPI-3 from Rover.. That pretty much means dissecting it all. Not looking forward to that as I remember how much in pain-in-the-*** is was to put this together. Damn tiny screws..
Darn.. they goes a nut somewhere into the basement into the never never land.
Darn.. there goes another never to be found again..
Kevin.. if your ears are burning it is because I am cursing you for designed this to be so miniature and pretty much un-serviceable. On the other hand it is like the real Mars Rover. On another planet and un-serviceable.
I think there should be mandate. Only 4-40 should be the smallest screws and nuts allowed.
Finally 15 minutes later the RPI-3 is in my hands. Hours to put it together. Fifteen minutes to take it apart. The irony.
Now the RPI-3 is sitting by itself. I Plug in monitor, keyboard, mouse and video into RPI-3. Plug in 64gb that was in it when it booted to four raspberries. Plug in power. no raspberries this time. The power LED comes on the board. Nothing else.
Unplug power. Pull out 64gd SD chip. Immediately drop the SD chip as it burns my finger tips.
I am guessing at this point my RPI-3 has a serious problem and not my card reader/writer. Three dead SD memory chips.
Lucky for me I can order another RPI-3 for my Spirit Rover unlike the Spirit Rover on Mars.
The big questions is what could cause this ???
I can not see how running some possible bad code could turn a RPI-3 in a self destructing SD card monster.
Has anyone heard of this happening ?

For those of you with more experience - is this likely a bad servo, an issue with the connection or something else? Suggested next steps or things to try?

Thanks for any suggestions.

my Spirit Rover's other motor broke down very quickly after testing it and the axle does not spin when loaded, even though gears are rotating in gearbox. Are there any tips on how to fix it or should I just order a new motor? Does anyone know the specs for the motor with the microgearbox? I can find a bunch of different types in Alibaba for example, but would appreciate if anyone know a reliable and compatible choice. I tried asking it from Plum Geek via e-mail but have not received any answer.

The code performs the following functions:
Passes all sensor data from arduino to the pi
Pi transmits all sensor data over WiFi to a server (in my case an ubuntu VM)
Server runs logic similar to demo mode 2 and pushes instructions for actions to the Pi (edge detection, range detection, servo moves, pixels)
Pi pushes motor/servo/pixel instructions to arduino/PIC
Server draws real-time graphs of sensor data and motor speeds

Additionally, the Pi can stream live camera feed using webRTC but this is coming from a packaged solution and not code that I developed.

I followed these instructions directly while connected to my Raspberri Pi:
I ran raspi-config and tried Expand Filesystem, but that didn't work. I suppose because it was already expanded?
Then I enabled SPI and I2C.
Then I ran sudo apt-get update and sudo apt-get upgrade and... it didn't start anymore.
I was able to start Raspberry Pi in safe mode, where I got to NOOBS, but even reinstalling the Raspberry Pi didn't work. It crashes almost immediately when it starts writing to ext4.

Is this recoverable somehow? It doesn't look good.
