RetroPie going back to a point in time (snapshot/deepfreeze like)

@vladquebec i would check the free space on the sd card (df-h), maybe the filesystem is full, or needs to be expanded. see: https://github.com/RetroPie/RetroPie-setup/wiki/FAQ#how-do-i-extend-the-available-space-when-upgrading-to-a-larger-sd-card

@vladquebec Check the permissions on the ROM folders.
Save states are written when you exit cleanly from the emulator, so make sure you're not restarting by resetting the power during the gameplay or while in ES.
Give us more info about your setup - https://retropie.org.uk/forum/topic/3/read-this-first

When SD cards go bad, they go into read-only mode. This is to allow you to get your data off the card before it dies entirely. My suggestion is to back up your SD card and replace it.

@vladquebec Hey please try the following with a new card of equal or more size. I agree with @zerojay, when SD cards go bad there is nothing that can be done other than recovering your data (if lucky).

sudo dd status=progress if=/dev/mmcblk0 of="retropie.img"

# change sd card to new/spare of equal/more size and then
sudo dd status=progress of=/dev/mmcblk0 if="retropie.img"

If you get IO error with dd your sd card is kaput.

@hex Thanks for the detailed answer. I did try the command, but it doesn't work :

dd: invalid status flag: ■progress■

Is there anything I am missing?

I had thought my SD card was bad, but it's not even a year old. I know problems can happen early, but it seems weird at this point...

zerojay

@vladquebec I don't think I've had a single SD card last anywhere near as long as a year in a pi.

@zerojay Thanks for sharing, something new I've learned this week. :-)

Follow-up : just ran a surface scan of the SD card, while inserted into my laptop, everything looks fine.

Don't worry, I know it doesn't mean that's not the problem, but I thought I'd mention it.

@mitu Thanks for sharing this, I'll come back with a detailed list of what I have on my side.

Built From: Pre made SD Image on RetroPie website (retropie-4.2-rpi2-rpi3.img
USB Devices connected: None
Controller used: PS3 controller (wireless) and a keyboard/mouse when required (turned off most of the time).
Error messages received: None in this case.
Log found in /dev/shm/runcommand.log (if relevant): no such file there, no logs

@chipsnblip I've had this thought as well, concerning the free space, but it doens't seem to be a problem, here is the result of the df command :

@chipsnblip Did an expansion of the drive as recommended, but didn't do anything, reverted back to its original data at startup.

Found out the problem isn't only with RetroPie, it's with the rest as well : enabling SSH for terminal access reverted to disabled after reboot.

Hex

Where did you run that command? On your Linux PC I hope.

If yes you can just skip the "status=progress". It just provides feedback. Without that it will process but you will not get any feedback till the entire process is done.

@vladquebec, i'm curious to see if it's a permissions issue somewhere, post the outputs of:

cat /etc/fstab

and

 cat /boot/cmdline.txt

and

ls -l /

(no need for sudo)

Follow-up of something I've tried : I downloaded the most recent version of RetroPie, 4.3 and completely deleted the 2 partitions on the SD card. The part deleting the largest partition, containing the RetroPie data, took a long time. Right after I unplugged the SD card from the computer that I used to format it, I plugged it into the Raspberry Pi, and the partitions, including the data, were back. This clearly shows the problem is with the SD card.

At this point there are 2 possibilities (1 more probable than the other) :

The SD card has begun to fail and cannot accept any changes.
Some sort of read-only mechanism has been enabled, making it impossible to modify anything on the card (less probable, but still a possibility).

@vladquebec If you cannot flash imgs to sd card, your sd card is dead. I have one that went dead and partitions/files cannot be changed anymore.
