32GB Sandisk Micro SD suddenly stopped being recognized by Galaxy S3 phone

I had the same problem with my Galaxy Note 2. The card also cannot now be recognised by either my PC or Macbook. Amazon offered to take the card back but since I cannot wipe the data off it, I decided against this option. Really disappointed as all previous Sandisk cards have worked well.

I have almost the exact same situation. My card is a 32gb UHS-I card. I tried all the things DaveHo tried. I also tried formatting the card as FAT-32, and that also did not help. Thankfully, I was able to get my pics/videos off the card via a card reader on my PC before it seems to have become useless. For now, I am using a 16gb Sandisk card in my GS3.

I will be trying a warranty replacement. Hopefully that goes well.

I have also had this problem, as have a lot of other Galaxy S3 (at least i9300 model) owners on the xda-developers forums.

It appears to affect other manufacturers as well, not just Sandisk.

I have had the same problem twice now, with a 32 gb card. Sandisk will replace it for free, but it happens every 3-4 weeks. They are sending me out a new one again, This is exactly what they said. I think it bad memory cards.

Hi Rick,

This problem should not occur again in the Samsung Galaxy S3. The issue with your phone is a unique case and its unfortunate that it has occurred more than once.

We apologize for the inconvenience caused.

I had the same problem twice now. They replaced it twice now for free but lost everything. I never had to backup my data from sandisk, each one only lasted 3-4 weeks. Both 32gb were purchased from walmart. I have not tried the new ones they send yet. maybe they fixed it. Can only hope so. This is what they said.

   I had kind of the opposite problem. My new 32Gb Ultra card wasn’t recognized in any device except my Kocasio Tablet, which said it had 157 *megs* available. Using the adapter didn’t help. Then I tried one last device: a polaroid HD camera, with the adapter, and for some reason that got the card recognized. I immediately reformatted the card, and now it seems fine - recognized as 32GB in all devices and working (although it seems  a little slow) in my tablet. Is there any way to tell if these cards, which don’t seem to have serial numbers anymore (in the photo, anyway. Do they in reality still have them?) are counterfeit?

Sandisk may or may not be the world’s best, but this feeble attempt at ingratiation will not prevent your spam be being deleted and you banned from this site!

:angry:

I purchased a 32Gb Ultra uSD back in December for my Galaxy Note II. It’s been running since then, but noticed last week it would spontaneously “unmount” and then the phone would see it and remount it. Now it shows up as a “Blank SD card”, but won’t even allow itself to be formatted by phone. It won’t even get recongized by any number of PC’s ( or my Mac ).

At this point, I think I need a warranty return, and just take it on the chin that I’ve lost all the pictures of family during the holidays.

Anyone else have any ideas ?

friends,
I am also facing same problem with my 32gb class 10 memcrd. it get frustrated when I see no content in card. I wonder sandisk could not trouble shoot this common problem. I get no messges or notification like others do. as my content goes invisible I see no memory card recognized. only notification I get is " checking for errors". but after few minutes I will recognize by itself. this problem repeats very frequently and this is most disgusting. I got off mem card connected to card reader and scanned in my computer system for errors,. but there was no errors found and also formatted (notquick) and placed again in my note 2 but this problem was still continued. I also formatted in ntfs in comp but after inserting in note 2 it could not recognize the format and automatically asked to format from note and it did successfully. here I thought the issue with mem card has resolved but after some time started the same. I regret I would had gone for samsung memory instead of the sandisk. so as I note see many of people facing same problem as me and now it is confirmed that this is not the problem from samsung galaxy note 2 but this moron SanDisk memory card. I only request the company to launch the bug fixer in way out of software and eliminate this issue.

I am so frustrated with this Sandisk 32GB SD Card. Suddenly my phone crashed and It stopped getting detected by the phone or PC. They are giving an option of formatting the card. Even after formatting it is showing Blank card. Can anyone help mw to recover all my favorite pictures. This is so sad. I have all my travel pictures in the card. Please please help if the data could be recovered, Thanks.

Same thing just happened to me on my Galaxy S3. I bought my card at Costco and I just returned another one for my friend last week. It bothers me that SanDisk has not put a comment on this thread when it is obviously happening to a lot of people. 

Both my Note II and my wife’s Galaxy S3 had experienced the same problem.  don’t know what was going wrong to ScanDisk product…!!!
