Re: Corrupt SD. Can I recover files?

The easiest approach I know is to set up an entirely new sd card...don't use the old one...load the OS and then use a USB card reader to see the files on the old sd card. You may not be able to open the boot partition but files that were saved on the old root partition may be recoverable. You can th...

Re: Pi 2 won't load to main menu

Very nice that they put chromium in the latest iso but if you don't want to install it just now, the method works. Nothing is outdated about the advise against pulling the power plug or removing the sd card before a proper shutdown sequence has completed. That is the best way to protect against sd c...

Re: Issue with USB boot

USB boot still has not gone mainstream on the RPi 3. I would stick to a single USB disk in the mean time...get a bigger memory if you need more space. Even setting up the USB boot is tricky and the slightest thing will mess it up. Problems like yours may be why it hasn't been released yet.

Re: Pi 2 won't load to main menu

It sounds like you may have corrupted the boot partition when you pulled the plug on the Rpi. Your best bet is to set up anew SD card and load Noobs, choose an OS and reload. If you have files on the existing SD card, then you can use a USB card reader to look for them and copy them back to your pi ...

Re: Quiet boot not working

You should run

Re: Noobs filename & sizes

When the Pi doesn't boot, it is most often a failure in the boot partition. I suggest you use the SD Association's free SD Formatter utility if you have windows or mac or gparted if you have only linux. Format the entire drive as FAT 32 and then copy the image file per the instructions. (Gparted may...

Re: Relay causing phantom edge detections

Is your relay board home-brewed or purchased? The Sainsmart relay board I use isolates the relay coil from the GPIO output with an opto-isolater so the drive is not being taken directly from the GPIO pin. I take the relay drive directly from the 5V pin on the RPi. Also, are you using an anti-flyback...
