Sd card problems

O.K. Thank you, Unfortunately The Sd Card can get a full memory and then it can not load the updates! I have had a problem that the SD card appears to be Read Only and can not be Formatted to clear existing files using Windows 10! Raspberry Shake is the only program that I have that uses RPi and I do not have any experiance working with this OS. I tried with a new card (Sandisk Industrial 8GB) formatting to Fat 32 and then Unzipping the Files from my PC to this Card. It appears to start O.K. then after a short while it says that the Card is Read Only and has a Cyclic Redundancy Error! I then tried Reformatting the new card and get the same Error! I have spent many hours searching Google and I have not been able to resolve this problem. It would be nice if the card did not completely fill and if some space could be reserved for updates, or at least give some notification that the card is near full, or even automatically clear memory when it starts getting full? For now I am just wary of buying a new card and encountering the same problems. This is why my Raspberry Shake is offline! Any help would be appreciated.

Hello Brian,

I’ve moved this answer to a new thread, so we can take care of it here instead of prolonging the other one, even if they are related.

This is a very unusual error since the entire Shake OS is not so extensive to entirely fill up an 8GB microSD card. I have tried to replicate this problem with two of my computers, both with Win10 and using the WinRAR software to extract the files, but I was unable to, unfortunately.

What software are you using to extract the files from the Shake OS zipped archive to the microSD card? Since you have already tried with another card (good thinking) and have obtained the same result, have you tried to extract the files with different software? On a different microSD card adaptor/port? Or with a different computer?

An 8GB microSD card will take usually weeks to become completely full, but even there, there are limits that the user can set so that this never happens, and there is always space for new data. It seems to me that this problem is related more to the extraction process involved in burning the new image.

I have Tried with the built in Formatter, The SD association Formatter and EaseUS!
I have not been able to reformat these SD cards after trying to unzip the files from the PC to the Card. I have tried both the built in SD card reader and an USB adapter. To Unzip again using the built in windows Program! I am old and not very adventurous computer wise. I only do thing differently if I am forced by circumstances! Regards to the Card memory filling up, I refer to normal usage sometimes I forget to clear the available memory and this is when the card got full, unfortunately the update occurred during this time!
Basically what I want is to be able to reformat these 2 cards, unzip the program to one of them and fire everything up again?

Hello Brian54,

Thanks for the specifics of the pc, I cannot see any faults with those, since the requirements to do this work are indeed minimal.

EaseUS should have done the trick, however, since with that tool it is possible to see the partitions inside any disk and erase them all to restore the disk to its original state. Could you please post a screenshot of what EaseUS is showing when you insert one of the microSD cards that you have tested?

I don’t know why the microSD cards, at a certain point, become read-only. This has never happened to my memory so I am unfortunately unable to provide a reason.

I normally use the command line tool diskpart to format everything if some issues similar to this happen. You can find a step-by-step guide here, How to Format SD Card Using CMD | Terms and Tips, however, it can be a more complex process than the others tried until now.

O.K. I will try and get a Screenshot for you today! I am very busy and I am trying to fit this in between other things!

I have Screenshot the whole process! I hope this makes sense. As you can see the original files are still there on the SD Card after all these deletes, cleans, formats, check disk etc? However, they will not start the Raspberry Pi, nor run the Shake program.
Thank you for your time, I am sorry that this is taking so long! (Nearly 4 months now!), but I can only do this when I am not busy with other things!

Hello Brian54,

Thank you for all the screenshots. It definitely seems that there is some corruption in the microSD cards, at least from what I can see by looking online.

I have found these two pages that could provide a solution:
https://www.easeus.com/resource/fix-data-error-cyclic-redundancy-check.html

Unfortunately, I am not sure of what is causing this error, so I cannot be more precise. It is not related to our Shake OS, so, if all fails, it could be worth acquiring yet another microSD card, to test if these two were damaged in some way. It has happened in the past on some rare occasions.
