Sandisk 64GB micro SDXC on my LGOG - AT&T LG Optimus G
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-- OMG i did it with my outdated laptop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.

[Q] Troubleshooting Micro Sd for Galaxy S3 - My findings & Questions
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 . jje
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.....
Sony Tablet S - SGPT 112 DE/S 32Gig an SDXC 64gig SDCard
First. Sorry for my Bad Englisch. Question Support a Sony Tablet S - SGPT 112 DE/S 32Gig an SDXC 64gig SDCard I have Purchased a Sandisk Ultra SDXC 1 64Gig Class 10 30Mbs It not Work. The Tablet say. Please Insert a Storage Card. Format with FAT32 not help. With the SDXC Card inside, after boot the SDCARD Internal Memory is not Show Anymore. Is the Card incomatible or generally SDXC
what version of android do you have now? You need ICS release 6 for sdxc support!
I may be mistaken, but I recall support for SDXC memory cards formatted exFAT was first provided with the 4.0.3 release 6b firmware update. However, SDXC memory cards formatted FAT32 can be used with earlier versions of firmware.
My Tab have Android 4.0.3 realeae 1a Kernel 2.6.39.4 Rooted. Format as FAT32 not help. The Tablet Say Insert a SDCard. SDCARD Memory is gone. Another Format as NTFS with the Paragon NTFS & HFS+ APP not Work. Same issue.

Is it possible to Add Support to Android 4.0.3 realeae 1a? :

All you have right about sdxc ExFat format. Look at your sony site there is an info/statement about sdxc. Check, its there where are news about update . These sdxc formated are incompatible with sgpt 111/112/ 113 NOW . Maybe in future will be comp - who knows . I didnt check xts statement. ...but koto u can change sdcard format to Fat32 and you will have working with tab card. I personally have same card as you but microsdxc 64GB with sd adapter. I resolved this problem by formatting it with my android phone (lt18i .4.0.3) .Exfat changed to Fat32. You can format it also via PC tool ( my case : I formatted my card first on PC win xp and after I have 32Gb card instead of 64. After that read somewhere that some OS ( windows generally) have restriction of reading Fat format to 32gb - but it doesnt mean that it cant read it. ) . Linux should read and be able to format to fat32 >32gb sd . Search 3 rd party app for pc to formatt. Btw i have 4.0.3r5a,I can confirmed this card working also on ( 4.0.3.r5 ,4.0.3r1) koto99 why you want to have ExFat formatted one ? transfer >5gb?You can also plug external hdd with ntfs and drive mount app with rooted tablet. Drive must have external dc to give own power supply. Attachments : https://www.dropbox.com/sh/jicfvqdu2mfd6iu/Mx_4IoJZj0

Yes Windows 7 64 Bit can Read an Write FAT32 SDCard. Card work on PC Perfect. See
Strange... Under Windows it looks good. Then only people who have personally experienced the case can help you. Sorry!
I pushed question about it to sandisk support. I ' ll post what they answered after I receive it. Btw. read in support about sony nex-7 and sdxc. When formatted in camera windows 7 (which is compatible with exFat) sees as unsupported. When card is windows 7 formatted nex-7 sees as unsupported. Btw1 about screen at #11 I see used space at 64.0KB. I experimented sth.After I formatted card the used space were same as I set in format tool in cluster size option. I tested this with easeus. Set to 8.0KB cluster size- after format used space was 8.0KB. If this screen is shortly after format you may set in format opt 64.0KB cluster.Did you try 32KB cluster? My Lt18i formatted my microSDXC as 32 KB cluster size and have active/ primary in easeus option. BR
Formatter is http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm Quick Format Cluster 512, 8192, 32768 nothing work Tablet not See the Card. EaseUS Partition Master 9.2.1 Home Edition not See any SDCard. Format impossibel. (Windows)
As I promised here is an answer from sandisk technical support. Maybe some info there is obvious. I want to post state of manufacturer. In my mail I asked if sdcard can be damaged permanently by formatting it to fat32 and consequences about that (in my sgpt111). Also asked about tool app to format inside tablet( most tablets don't have that option). Check the tech repply esp "the only consequence". Dear Customer, Thank you for emailing SanDisk Technical Support. It is our goal to make sure you have all the resources you need to get the most from your product. I understand that in exFAT, the 64GB microSDXC card is not detected by your Sony tablet. This is because the tablet doesn't support exFAT. After formatting the card in FAT32, the card seems to be working fine in the tablet and shows the full capacity. The only consequence you may experience by doing this is that you won't be able to add any files larger than 4GB, due to the FAT32 limitation. Transferring a 4GB or larger file to a USB flash drive or memory card http://kb.sandisk.com/app/answers/detail/a_id/289/kw/4GB You will be able to format the card back to exFAT, if your operating system also supports exFAT: Operating Systems that Support the exFAT File System http://kb.sandisk.com/app/answers/detail/a_id/3389/kw/exfat If I understand correctly, you would like to know also if there is a difference between the microSDXC card and the SDXC card. There is indeed a physical difference between both cards: - microSDXC: SanDisk Ultra microSDXC UHS-I card for mobile devices www.sandisk.com/products/memory-cards/microsd/ultra-class10-for-android/?capacity=64GB - SDXC: SanDisk Ultra SDXC UHS-I Card www.sandisk.com/products/memory-cards/sd/ultra-uhs-1-class10-30mbs/?capacity=64GB Regarding your question about the format option tool for the tablet, there currently are no development plans on this. You may keep an eye on the SanDisk webpage to see if there would be any plans on this. Click to expand... Click to collapse BR biablo

Empty MicroSD normally with 64GB now only has 32GB even when empty. (32GB gone)
I have a Sandisk 64Gb MicroSDHC card. I've been using it for sometime on Android and. I've used Android to format it but never to partition it. I've also used Android to wipe data on the card. I've formatted it varous times again on Ubuntu. The card was working fine but today, I decided to format and clear all the data on it. Much to my dismay, after when plugging in the card and formatting it, Windows read it to have only 27.8 GB space even though it was empty. Ubuntu also showed 27.48 GB only. I've not much problems with the card on Android and Ubuntu but today, this serious problem occured. Just how does a 64GB card reduce to 27.48GB? I've formatted the card to FAT32 and EXT4 multiple times to no avail with GParted. Previously, some time ago, I've formatted the card to FAT32 and because the computer, I forgot if it was Windows or Ubuntu and because the computer read it as having 30GB space, named the card 32GB Volume or something like that (The name has long since changed to one of my choosing). However, Ubuntu still read the card as having 64GB of space and filling it up with more than 30GB worked just fine. What happened? How do I resolve this? I need the card to work on both Ubuntu and Android. This is my card. http://www.amazon.com/dp/B005V7WIA2 Based on reviews alone, it seems to be very good quality. I've used the card on Ubuntu, and Motorola Defy (Android), and the Motorola Xoom (Also Android). Both Android and Ubuntu have worked with the card just fine except for one thing Occasionally, when copying files to or from the card, I get an error message. Sorry but I don't recall what the message said.
SD Card Won't Mount
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 Sent from my B1-730HD using XDA Free mobile app
[Q] whats the biggest sd card supported
I was wondering if i could use a 64gb sd card on my ham2. I currently have a 32gb but thats a bit small for me. Thanks

I too am using 64GB -- formatted to FAT32. If I recall, my card was pre-formatted with 2 partitions which the phone will not recognise. If you format it to NTFS, TWRP might not recognise it in recovery mode. Windows will not format such a large drive as FAT32, so you will have to use another tool -- e.g. MiniTool. The caveat is avoid using a (cheap) USB card reader. I've corrupted the card before when transferring too much data to the card. Newer readers built into your laptop or using the USB cable directly to the phone seem okay.

Just be sure you get something beyond first gen (40,MBS) cards. I have had 0 issues with anything up to 64gb I now have two 128gb cards that both work but get corrupted and require a format every time I attempt to transfer 10 + Gigs of information at a time.
