This card has been working well and is running Raspbian. I keep it well updated, although recently I had an issue where I had an error in the /var/lib/apt/lists/ and had to purge all those files before the last update.
I'm also using the 1000 clock speed with force_turbo, but this isn't supposed to invalidate the warranty.
Then today one of the kids wanted to "play games" on the RPi (it's connected to the TV and I usually just run headless). And it had a blank screen. Nothing particular had been done on the machine/drive, certainly no partition modifying operations.
I noticed my always-up terminal had an error:
pi@raspberrypi:/boot$ Write failed: Broken pipe
When I power-cycled it, I saw it was unable to boot.
I am able to boot another SD with an old Occidentalis image, so I think the hardware is OK.
I put the SD in my Ubuntu and set the config.txt back to 700MHz, but the problem persisted and I put the card back into the Ubuntu system and I seem to be unable to mount the second partition on that SD card. It should mount with ext3 or ext4 right?
This Sandisk 8GB card has been reliable (I bought 2 2-packs, so I have 4 of them with various distros on them) - I guess it's possible that the problems with the apt-get file lists might have been a sign that something was physically failing.
So the culprits could be:
- Bad card
- a hack? (it's still set as pi/raspberry, but shouldn't be accessible to the Internet - I only have some port forwarding to my Panasonic IP cameras)
- something else?
Looking for some ideas if there's something I need to avoid before I reformat and rebuild because I'm going to use the latest image and manually rebuild the system.
UPDATE: I did apparently void the warranty by overclocking with some incorrect settings when the authorized turbo mode was first publicized - not sure what I did, but I put on Raspcontrol and it was from there I saw that one of my RPis had a valid warranty and one did not. I assume this contributed to the SD failures (I had one since this one). I no longer overclock and am waiting to see improvements from the RPF for the USB and SD behavior.
