Boot-up error

Sat Feb 23, 2013 11:23 am

Hey everyone, I need some help with my Raspberry Pi.

Today I started using my Raspberry Pi. I turned it on, and it booted up normally. I then started programming my own calculator in IDLE (I use Wheezy). I finished the calculator and then shut down the Pi. I then turned the power off.

Later, someone asked to see the calculator program I had made. I turned the Pi on. I was then greeted with some strange code which involved the word 'ok' written in green.
The Pi then said something along the lines of a maintenance being carried out and to press control-d when it is over. The Pi then started a long list of errors, all numbered with two new errors being produced about every second. Each line starts with the number, followed by EXT4-fs error and then some more code.
The errors keep counting up, they are currently around 850. Every 70 or so errors, a different bit of code comes up. I have tried switching the Pi off then back on again, but the same thing happened
I desperately need help, I really want my Pi to work. Any ideas how to stop this? Thank you.

If you get errors like that there's a good chance your file system got corrupted somehow. If you have a spare computer with linux and a card reader you could try to insert the card and running a filesystem check on the ext4 partition (fsck.ext4). Although it puzzles me why would such errors suddenly appear after a reboot. Was the SD card new?

Yup, probably need to reimage the SD card and start over. That points out the necessity of saving off periodic images if the SD card so you can always go back to the most recent working version.

yeah, the SD card was new and bought already-flashed.
as i have no idea how to run a file system check, i think my only option is to reflash the SD card.
any other suggestions?

Since you are just getting started, it's not worth the effort to check and attempt to fix the file system. Just download the current version and load that. Raspbian Wheezy is the way to get started. Once it is up and running make sure that you save off a copy of the image before each new modification.
