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

Hi,
I searched around but can't seem to find any help with why I can't flash ROMs from 32GB cards. I've tried it with a class 4 Topram card then after I returned it I tried again with a class 2 Sandisk . Everytime I load the bootscreen for it to search the root of the card for leoimg the screen just flashes and continues to bootscreen without finding the ROm file.

May I suggest you try a maximum size of 4GB microSD card and format it with FAT32.
I honestly couldn't reproduce the threads right now, but I seem to remember reading about this issue before, concerning both 8 and 16 GB cards - So it seems logical it would apply to 32 GB cards as well. I don't know whether this is related to memory addressing issues or some other limitation - FAT 32, perhaps? (please, someone enlighten us both if you know) but using a 2 or 4 GB Card prevents the problem from occuring altogether.
as above said, most 16gb cards don't work(only know one person who has said the successful y used a 16gb card) and many 8gb cards don't work, so its a safe bet that a 32 is not gonna work. 2gb seems to be the optimum size, but 4 should work too.
for me, i have a 512meg card i use on the very rare occasions i use sd.
well since I got my HD2 I've used its 16GB sandisk to flash ROMs to the phone and have never had an issue before but both 32Gb cards I've tried just don't seem to respond.
Thats rather strange.
Theoreticaly you should only be able to flash from SD cards. During booting a driver is loaded so that SD HC cards can be read by the phone.
i.e. everything non SD HC up to 4GB should work fine, everything SD HC above 4GB should not allow flashing.

My Sandisk 16GB SDHC card also works perfectly for flashing on the odd occasion that I use it for flashing that is
hmm, that is interesting, I can't flash from my sandisk 16gb, class 2. Not sure why others can.
I can flash from 8gb class2 and below though. I use a 2gb sandisk just for this purpose.
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.
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.....
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 .

google "h2testw.exe" for a good windows card tester.
Hi.
I'm trying to partitioning my sdcard to do the link to it and expand my storage capacity.
But I'm having a problem that when I made the procedures in my 32gb SDHC card, I can't get it right. Link2SD always get the invalid argument and the mount can't be created. I tried all the solutions that I found on internet before getting tired. So, I have this 2GB normal SD card and I did the procedure on it just to check if the problem was on the carrier and worked fine.
So, I wanna know if the problem is that the tutorials and workaround that I found over my searches doesn't work fine on the SDHC cards or if I'm doing something wrong.
My 32gb card function normally as storage for data and stuffs like this, but I couldn't partition it to use for the real purpose.
Thanks in advance for the help,
