Power failure, pi doesn't boot anymore

[zeff]

Hi all,

Due to a power failure, my Raspberry Pi doesn't boot anymore... When plugin the power supply, the red led lights up but the system doesn't start.

I think my filesystem has been corrupted, but how could I fix it and recover my data on the SD card (I'm not able to mount the ext4 partition on a linux machine...)?

Many thanks in advance!

Get another SD card and write Raspbian to it. Now you have a Linux computer. Put original SD card in reader and plug into USB socket on RPi.

I am having the same issue with this. if the power goes out, or I unplug the system while still running, the card will no longer boot unless I re-flash it.

Whilst genuine power failures "can't be helped", never just unplug power to the Pi, always shutdown cleanly first ("sudo shutdown -h now"), wait until all green LED activity has finished (no more writes to the SD card, usually 20 - 30 secs.) and only then switch-off the PSU - if you must unplug to do this do it at the "wall-wart" end rather than at the micro-usb connector. That way you reduce the chance of ending up with a corrupted SD card to almost zero. Of course, if the system hangs (equivalent to the Windows "blue screen of death") simply unplugging is the only way, but this is as a "last resort" not "normal practice".

Thank You for the advice. However that has not been the issue. It really has been you average everyday "Uh oh the lights went out" power failure. This happend a couple of days ago once again during an electrical storm. Upon restoring power the Pi would not boot once again.

Something I did notice during this round, the Act light was working so I left it for a bit and the Pi eventually as it appeared to reset itself. This took approximately 2 minutes.

I am currently running Debian with my own install of SLiM DM and Openbox WM.

To shutdown I use "sudo halt". Less to type out and does the same as "sudo shutdown -h now".

FWIW, "init 0" works just as well, and is even easier to type. That's what I always do.
