So I purchased this Micro SDHC card when I was overseas thinking its a decent deal.
It was a Verbatim 16gb Class 10 (Verbatim 44010)
Long Story Short:
I had to format the card to exfat in order for my phone to write to it.
Using fat32, the phone can read the card just fine but can't write to it.
If I tried to format the card with the phone, I get the same problem (I guess the phone formats it to fat32?)
The card reads/writes fine in both formats when plugged into the pc
What do you guys think? Something is wrong with the card?
A its a question .
Probable faulty card .

I9300 and 8GB SanDisk Class 10 SDHC
This is the version that is branded as ideal for Android that came with a Sandisk application for you to download.The card has been working fine for 1 month and then suddenly while my computer can read/write to it just fine....the S3 can only read the contents from it but can't write to it. It is originally formatted to FAT32, now my phone can't copy files to it (whatever file types) using the stock file app and the camera won't even save photos to it with an error that says "copy failed" or "can't save to storage".....Having seen this post being the closest to what I am experiencing, I am wondering if I should try exFAT too.....

Hello there,
I just bought a 32GB Class 10 Samsung MicroSD card.
After inserting it, I made sure the phone sees it, and the computer sees it.
So I started transfering files to it...
Every time I try to transfer files to it, the cards sort of unmount, the computer stops seeing the External/Internal storage drivers info (0/0 KB and no files).
I realized I might be needing to format it, so I went to recovery and formatted the external card. Still no good...
If I don't try to transfer files, the internal sd card still works fine.
Am I formatting it wrong? or some other issue? Did I buy a faulty card?
Thanks!
P.S. Some info incase needed:
Using Galaxy S2 obviously, Resurrection Remix ICS 4.04
My PC is running XP SP3
[edit]
Added some pictures to demonstrate what I mean.

Pic 2: The error I get, doesn't mean much except that the pc doesn't recognize the storage device, but just for the heck of it.

If unsure about the quality of your SD card google for h2testw. It is a Windows test software you can use to test your SD card.
Tried formatting it... still no good.
And h2test tries to copy a file repeatedly and after some time it also gets stuck like I do manually...
I was running into the exact same issue as you with an SD card awhile back. Tried many, if not all of the suggestions listed here. Sometimes, the cards just die on you, especially at the most inopportune times...

Open CMD
Type format [letter_of_external_card]: /x
ex.
format E: /x
and wait.
Then format again (through Windows Explorer) with this settings:
FAT32
default allocation size
fast formatting checked
and share the results.

Failure of h2test is normally due to defective hardware.
For SD cards I do not really know but when it comes to USB sticks there are many around that are just cheap crap. You could for instance buy a 8GB stick that will happily accept 8GB of data but only store 4-6GB!. This is where h2test comes into play: it will not only write but also read and therefore check if the data written was really stored in the flash.

Class 10? That card might be just too fast for your hardware.
I'm using Sandisk 32GB Class 4 and never had any problems.
I have tried some Class 6 and Class 8 cards with very various results.
Only class 8 card I found correctly working in my device was Memorex, but it was only 4GB.
So I gave up on fast cards...
its fake or corrupt,did you buy the samsung off a retailer , you always test flash with h2testw before you use it, speed is not the issue,i got a class 10 32gb i had many 16,256,4gb fakes, only 3.7 gb usable droped down to 1kb write then windows couldnt read the storage so you reformat again.
Hi all, i'd like to share my experiment with this new-tech thing.
I bought a Sandisk 64GB micro SDXC class 10 the other day to be used in my new LGOG
I formated the card using my win 7 laptop as exFAT then put it in the phone. At fist it mounted fined and has no problem. Then I copied several GB of data to the card within my OG and the problem happens: the card unmount itself continuously after 1~2GB copied. It keeps unmounting and remounting for a few times before it mounts normally as the message appears "SD card unmounted unexpectedly".
That started making me worry so much. When it mounted normally I try listening to music in the card, after 30~60 mins of playback the unmounting problem came back.
This became so annoying that I tried to find a solution. Below are what I've tried which the problem still happens afterward:
- Formatted as exFAT in Windows 7 laptop. Not work.
- Formatted as NTFS in Windows 7 laptop. Not work.
- Formatted as FAT32 in Windows 7 laptop. Not work.
- Formatted as DOS-FAT in Macbook Pro 2012. Not work.
- Formatted as exFAT in Macbook Pro 2012. Not work.
- FULL formatted using SD Card formatter 3.1 (sdcars dot org). Took me more than 2 hours, still unmounting/remounting.
I did some researches too and found out a lot of interesting things
According to sdcard.org:
- Must use the card with SDXC compatible devices/adapter.
- Do not format SDXC card using incompatible devices/adapter <-- OMG i did it with my outdated laptop
And from Amazon reviews:
- Do not format from the SDXC card or it may cause instability. <-- this is the strongest reason I believe
- This Sandisk model is not compatible with Android 4.0 or above. <-- What the hell do they make it for? If you are curious enough to read the review then look for: Designed incompatibility/Don't support SanDisk By Tom Henriksen "Doggy Diner"
From all the evidences I could gather around I am stuck and the beautiful combos LGOG + 64GB class 10 is broken.
Ended up returning the card. Looking for a more stable one to dig in.
Thanks for reading and please share your experiences. Any comment is welcomed.
If you had googled a bit before trying this you would have known to just format it to FAT32 out of the box instead of all those other formats. You probably fried the card.

There should be NO issues with using this card I think this is purely user error.

I had this exact problem. Same issues on my lgog but worked fine plugged into my laptop using supplied adapter. As it turns out the card was defective. I contacted support and they agreed it needs to be replaced. Now the same SanDisk 64GB model new card is working perfectly so its not you, its the card.
I originally formatted my 64GB MicroSD card for my SGS3 and, after some research, I downloaded the free version of EaseUS Partition Master and formatted the card using FAT32. It's not the most efficient use of space on the card, but it works with both ICS and Jelly Bean quite well. And, it's now serving me quite well in my OG. :highfive:
Can one of you guys with that 64GB sandisk card see if you can make an EXT 4 partition on it in addition to a FAT32 partition and see if it works? Like SD-ext partition? It would be really nifty for using it as a flash drive/keep a couple 1080p bluray rips for miracastin' on there.
My Galaxy S3 and my Kingston 64gb class 10 microsd card have not been getting along. Very important files have been getting corrupted. Anyone got suggestions? At the moment, I'm formatting to fat32 and putting .nomedia file in my music/sound related folders, but some google results suggest that will be a waste of time since I might have gotten a bad/fake card.
EDIT: Errr... can't seem to format to FAT32
Use a card tester sounds like a fake .
jje
google "h2testw.exe" for a good windows card tester.
First of all, im using a 4.1.2 stock and my device is rooted
So i had an Sandisk 64 GB class 10 for some time which one day became a "read - only" card...
So afterwards i bought a Samsung 32 GB class 10 which I found out also had problems because i could put about 10GB of files and everything more that 10 GB turned into wierd folders that their name starts with "μ" and there where no actual content inside and i couldn't delete them.
So now i'm at my third try, again with a Samsung 32 GB class 10 which also has the same problem, only now i can write on it about 20 GB of data before files start to get curropted.
Just want to say i bought all 3 SD card from Ebay, and though i guess they might be fake (tons of bad luck), after searching the web I found out there are many GS3 users with the same problem...
So i just want to put an end for this question..
Is GS3 frying SD cards? is there something i can do to stop it from destroying SD cards? can i fix somehow the SD cards?
thanks alot!
Hi! when you are asking a question you should include details such as operating system(4.1.2 , 4.3, 4.4, stock, rooted and so on) and file system. I noticed while searching google that the majority of "s3 fried sd cards" so to speak are sandisk and in your case it seams that there is no such "limitation". Maybe if you give more details someone might be able to help.

Well, I edited my post.
you can see the first lines contains the detailes you described.
can't think of any other relevant details.
What type of file system do you have on sd card? is it fat32 or Ext4?

not sure. I formated it with my GS3 and the computer won't recognize it without reformating it.
Worst case scenario is your phone somehow corrupted the sd card and that is that. I had a similar problem with my usb flash drive which i used on-the-go and unmounted it before removing it but when it happened i didn't make a backup(as always) and got stuck with a nice keychain. If you have the possibility to format it under windows with a card reader and choose fat32 at least you have a working sd card, otherwise use your warranty for the sd card(if you have one) and always BACKUP.

but do you think that my device is malfunctuning in a way that will keep frying my SD cards..?
well since this is the second sd card i personally send it on warranty(as hard as it may be without the phone) because it seems that something is not right with the contacts of the card reader circuit board. I read somewhere that on some phones the card reader slot had some contacts partially detached and so the sd card kept getting corrupted. Search a bit on google about this issue and take into consideration using your phone's warranty. Best of luck!
That is a bit strange. Unless you're used to remove the sd card with the phone accesing to it (no safe removing) or removing the battery while the phone is running, that's absolutely not normal.
I have my 32GB sd since 2010 and I never had any problem. I formatted it this year because it had tons of useless data and I liked to have it clean.
Of course it's not from Ebay! That is bulls**t and use to fail suddenly.
I know there are numerous posts on this, however I could not find one that addressed my specific situation.
I have a rooted Lg G3 with stock rom and I am trying to use a class 10 SanDisk Extreme (16gb). The micro sd card read just fine on my computer with no problem at all with reading and writing data, however when I plug it in my phone I get a dialog that addresses the fact that a micro SD card. But when I check the storage setting I see that it has failed to mount.
To see if its a functionality problem on my phone i mounted a class 4 SanDisk micro SD with no error. I tried formatting the sd card through my computer to NTFS and FAT32 with 32 kb allocation size (quick format switched off) yet still no luck. Is it a possibility that LG G3 is not compatible with class 10 micro SD Cards?
Any help would be appreciated, and thanks for your time.
Just to update the information I posted above, but I tried mounting the SD card on my friend's Verizon Galaxy S5 and it ended up successfully being able to read and format it. Maybe it's my phone? If so is there anyway of fixing it or possibly modifying it?
It is possible that the handset cannot read/mount Class 10 cards, I've seen it mentioned in threads before about trouble with mounting SDCards, Class 10 seems to be the biggest problem I've seem mentioned.
Use the search for Class 10 on the forums and see if a solution is available
