Title: 'Hard' reboot for the id
Post by: Geekspeak on June 03, 2015, 02:00:02 am
I am currently using my id in my car, and it is working splendidly!! However, I was wondering if I can remove a step...right now, I power the id down by pressing the button on the top..

My question is, can I just pull the plug? Or does it need a graceful shutdown. Also, if it does, do you know of any devices that can provide a graceful shutdown from a power loss?

I thought Linux was pretty resilient to abuse but I won't win any prizes recommending that it's always better to gracefully shut down when you can.

For automotive power supplies feeding sensitive electrical equipment, I'm aware of products like this:
http://www.carnetix.com/power-supplies (http://www.carnetix.com/power-supplies)
http://www.mini-box.com/DCDC-USB-200 (http://www.mini-box.com/DCDC-USB-200)

They both involve capability with a function to send a pulse to a motherboard power relay / jumper (thingy) to switch it on or off. The latter device has a preset mode that includes sensing ignition status and then delays powering up the device to make sure it doesn't get a voltage spike or current rush. Similar sort of deal when turning the vehicle off. You'll have to research the difference between the 2 if this concept rocks your world.

If you can get it set up and working right, that would be the best approach that I can think of because it would offer to take the best care of your gear. If you go down that path, feel free to update us with your progress.

I've done it more than a few times and not had a problem.  No guarantee ...

Linux filesystems are relatively robust, but sudden power loss can always corrupt a filesystem (even a linux filesystem) if you catch it at the wrong time.  Not all filesystem corruption is obvious either, so you might not notice until some of your media files don't work correctly, etc. 

Next generation filesystems with checksumming will help solve the issue of silent corruption, but for now better safe than sorry.
