RPi hangs on boot with ACT LED continously on

Mon Dec 14, 2015 2:24 pm

I have been using the RPi(Raspberry Pi 2 Model B) for the last few months on a regularly without any issues, however it has stopped working since last night where after reboot the Pi wont come up. Both the red and the green LED are glowing fully and the Pi is not booting up. Connecting it to a display does not show anything.
I hooked up the SD card to a card reader via USB to check if its corrupted but i'm able to access the file system. Upon checking the sticky related to boot issues, I saw that there are various states of the ACT LED which can mean different things, however there is no explanation of a continuously glowing ACT(green) LED. If anyone has run into this issue and was able to recover from it please let me know.

TIA !

Read the sticky again, because a continously glowing ACT means it's corrupted. You may be able to browse the files, but it still could be corrupted. How do you shutdown the Pi? Do you pull the plug?

Oops I somehow missed that line.. thanks!

Yes the Pi runs in an environment where the power supply is not continuous resulting in it going down at-least 2-3 times a day, and keeps writing data onto the SD card while its powered on, so I'm assuming somewhere something went bad with the disk write causing the corruption... :roll:
Is there a way I can restore the SD card without having to format it 'coz formatting the SD means I may have to reinstall a lot of the packages I have currently put on the Pi.

Try running fsck on it from another Linux computer. Google will show you tutorials and also Google for Linux Live CD if you don't have a Linux computer.

I would suggest in the future making the SD card read only and reading/writing your files on a USB stick so that the Pi will still run in case of an improper shutdown.
