SD card problem with the S3

[WAWood8]

I can speak from experience that is it not ALL class 10 SD cards that have this problem. I had SanDisk and Lexar class 10. These were the SD cards that were fried in the two GS3s.

I replaced the Lexar with Samsung, still class 10, and I haven't had this problem since. Folks in this and other forums have claimed that the Samsung memory doesn't have this problem -- and they may be right. Only time will tell.

Can you explain to me how you are using your sd cards??

-Are you taking it out of your phone and connecting it to an adapter and plugging it in your pc??...or do you just leave it in your phone always?
-How big of file sizes are you moving? Whats the biggest file size you have moved?
-Do you have multiple copy instances running while transfering?

I'm trying to understand if this is a phone, card or user issue.

BTW, I have had multiple cards in my experience and have only come across problems with read and write errors with cheap brands such as Lexar and Kingston.

Had been frustrating with my new Sandisk Ultra Class 10 32g that kept saying it is unexpectedly removed - till one day I was about to send my S3 in to demand for replacement, I did a final test of the card on other S3 & phones - & it had the same problem - SO IT WAS THE CARD....

Called Sandisk Distributor & they said it is a known problem between S3 & several SD brands but Sandisk has resolved the issue with the new batch of cards that has just arrived in Dec 2012.

Changed the card one-for-one & plugged it in immediately - Problem solved. Card remains usable again....

After reading the the last post I thought I can't deal with this intermittent 'card unexpectedly removed'. Now spoken to Sandisk and having the card replaced, they were laid back about it and arranged for a replacement.

The post after yours confirmed that this is a combination phone/card issue -- not just either one. I'm not taking my cards out of my phones but doing transfers by plugging the USB cord from the phone to my PC and transferring using a file manager app. The files are MP3 files, pictures, and videos -- of various sizes. The MP3s go from my PC to the phone; the videos and pictures, from the phone to the PC.

I used several brands, one of them being SanDisk. So, it's NOT a situation of using cheap SD cards.

And, as I said, since I switched over to using a Samsung SD card, the problems have stopped.

Visitor: also tried 8
Stewart: Thank you.\
Stewart: I am sorry, class 10 Sd card might not be compatible with the device. Please try to check with the class 4 to class 8 SD card.
Visitor: But on your site it shows 32gb class 10 for samsung s3
Stewart: I am sorry, there is no such information on our Website about the class.
Visitor: Samsung sells sd cards for samsung s3 correct?
Stewart: Yes.
Stewart: For product information or assistance with ordering please call Customer Support at 1-800-757-0280 to reach a Samsung Accessory Specialist.
Visitor: if so, the sd cards you show are rated 32gb class 10.
Visitor: If this is not correct, then samsung should be specific as to what gb and clas is appropriate
Visitor: for the samsung s3
Stewart: I apologize for the inconvenience.
Stewart: But as per the information we have Class 8 is compatible with the S3 devices.
Visitor: Since you do not have any complaints regarding this issue, I will forward to forums and friends so they may voice their dilemma. I thank you for your time.

From what I know there is no such thing as a "Class 8" flash memory product..at least not anymore. Also Samsung sells microsd cards in different Speed Classes. Each Description and Title specifically states the class on their website. Not only that the class # is branded on the memory card itself so you should be able to know just by pictures. Samsung has Class 4, 6, 10, 10/UHS 1 version memory cards for 4GB, 8GB, 16GB, and 32GB.

wierd... the exact same thing is happening to me right now... ive got a sandisc 16gb card, and no matter what, it just keeps giving that message. thats actually why im here!

I just got done reading this thread and hopped over to SanDisk Chat Support...
After explaining the issue that after 2 weeks of use my Galaxy S3 was not reading the 32GB Ultra class 10 MicroSD (message stating I "can safely remove my SD card", but never allowing it to mount or format otherwise) and when I tried accessing the data on my PC nothing came up at all as a drive, they advised:

Brad G.: As the memory card is not working in your phone and the computer in that case I can replace the card for you and you should not face any issues again with the new card.

This makes me believe that there was an issue with the SanDisk (and possibly other manufacturer's) cards that has now been recently resolved as stated earlier in this thread. If you are having this problem, I would definitely recommend talking to SanDisk, or whatever manufacturer of the MicroSD you're using.

hmm..exact same crap happening to me had the 32gb ultra sandisk for 2 months, no issues, jellybean rooted. Change to v36 omega rom, then stared getting blank sd card message. Coincidence maybe, haven't tried changing back to stock jb to see if it makes a difference but i think it wont after reading all the other issues there have been. Although i tried a number of things pc wont format it phone wont either, so i just left it in the phone low and behold 2 days later it was available again so i was able to copy everything off, then 4 days after that its gone again...very flakey indeed. Might try the chat thing with sandisk see if they can send a new one that does with the s3. Or maybe just get samsung 32gb sd card just so i know it works.

i have a class 4 sd card and have the same issue.... it worked properly for 2 months its brand new and today it just did the same thing as urs... tried formatting it still didnt work... thank god for google plus instand upload and dropbox

So I put in my 32GB Sandisk Ultra Class 10.... and today it already corrupted and I lost about 800 photos. Most of the more recent photos from that 800 did not have a chance to upload to Google+, as it won't let you "sync" if there isn't enough room in your internal memory. So unless they are still on the card but just won't work on the phone (I have the adapter at home) - I just lost a ton of photos.

What kind of is this? Literally, 1 day of use and it does this? Before I took it out, it wouldn't even let my phone function. It would just keep restarting. Should I contact Sandisk and ask for a replacement?

I really think it is an issue with SD ultra. Mine is not "ultra" it is older, never been a problem and most if not all of the posts I have seen on this concern the "ultra" card.

I have the same issue.

I got the 16g phone a couple weeks ago and added a 64g SD card.

I have hours of songs on SD card. It played them flawlessly for hours the first couple days. Now it will play music for a couple hours and out of no where it will only play 1-2 seconds of the song and go on like this for every song or it doesn't play them at all and get "unable to read this type of file". I will un-mount SD card and re-mount. It will work again sometimes. Repeat until it does work.

The card was formatted correctly and I load the music on it from laptop. Never had this issue with my old Droid Global but have an issue with it on my Samsung Galaxy S3.

If there is a fix, please advise.

I can tell you for sure that the class of the card and manufacturer is not the problem. I have a galaxy s2 and i used a genuine samsung 8gb class 6 micro sd card. It works perfectly fine with the s2. I upgraded to s3 in december and i took the card from my s2 and popped it in my s3 and since then the problems started. I formated the card under windows and from the phone but still no help. I gave up the ideea and popped the card back in my s2. It works perfect with it... Now i`m browsing ebay for a new card for the s3 but i don`t know what to buy as the genuine samsung card did not work with my s3. So...just to be clear,the class,the size,and the brand had absolutely no importance for me...

I did, and got a new one mailed to me.
Bought a SDXC 64g card.

How long ago was that? Have you had any issues with the new card?

Guys,

I had the exact same problem. I am using a Sandisk Ultra Class 10 32GB mSD card (loaded with pictures, music, videos, books etc, with only 4GB free space), purchased in Nov-2012. Before I upgraded to this, I was using a Sandisk Class 4 32GB card without any problems since I bought my S3 in Jul-2012.

For the past couple of months, whenever I press the power key, I will see the notification "SD card not found", then immediately, the card is found and everything works as usual.
Then, suddenly yesterday, I got the message "SD card corrupted, reformat?"

Of course I chose 'NO", then I re-booted the phone, and everything works.

This afternoon, the same "SD card corrupted, reformat?" came up and after I chose No, it automatically dismounted my card. Since then, The card cannot be read by my S3, even after I reboot. BUT, when I plug it into my PC, it works.

I started to search the forums and found that a lot of people has the same problem.

==> I just managed to get it to work!

I am not sure if this is the solution, but, after checking the forums, a lot of people are recommending that I format the card to FAT32. So, I backed-up my card, then, on a whim, decided to delete some videos until I have about 7GB free space, and plug it into my S3.

The card was recognized and seems to be working now. When I press the Power key, I no longer the the "SD card not found" message!!

Can it be that if we load the card above a certain amount of space, the S3 starts getting problems with recognizing the card?

Anyway, for the past hour, the card seems to be working fine and my S3 recognizes my Class 10 32GB Sandisk card. Will try for a couple more days and if it still works fine, then, this may be a temporary solution.

Let's see.. Will keep you posted.

I had the same problem. Every time I turn on the phone, there was an error message "SD card not found". Today, when I woke up, I saw the same message when I turned on the phone (S3), but te message was not go away. I further look in the settings->storage, and it was no help. I plug the Micro SD into my PC, it is not detectable. Tried with several Samsung phone, PC, but it still not detected. I have the San Disk 32G Class 4 Micro SDHC.
Can anyone advice me how can I recover the card, so I can do the backup of my Micro SD card which I had not done.
PLEASE!

My Lexar 16 Gb high speed SD card was working fine for several months. It stopped working while the card was in the phone and had just copied a large group of files and folders to it using Windows 7 and a USB cable.
I read a preceeding note about formating the SD card with a Mac. Therefore, I tried formating the SD card using an old XP computer. The phone can now read the card.

 

[AxlMyk]

How long ago was that? Have you had any issues with the new card?

It was mailed to me a couple months ago. I haven't used it because I put a SDXC 64G card in the phone. No problems with the SDXC. I DID NOT FORMAT IT.
