Hello,
TL;DR: I know how to format memory cards. The problem is; how do I get the Galaxy S2 to properly mount and access a 64 GB FAT32 MicroSD?
Long story:
I recently bought two brand new SanDisk 64 GB Mobile Ultra SDXC UHS-I Class 10 MicroSD cards (not on the internet, but from a reputable electronics retailer), in hopes of expanding the memory of my Samsung Galaxy S2 and Asus Slider SL101. I know that the Galaxy S2 does not officially support 64GB MicroSD cards, but after reading a few posts about successfully getting them to work after formatting them to FAT32, I gave it a shot.

Initially, both cards appeared to work fine. I plugged them both into my PC, and both cards mounted fine and appeared in the Explorer window as expected. And given that these particular 64 GB cards are designed specifically for use with an Android Smartphone, I put one of them (let's call this Card A - Card B hasn't been touched yet) into my Galaxy S2.
(Note: My Galaxy S2 was running Resurrection Remix 3.1.2 when I did this)
The phone booted up as usual, and I saw the "Preparing SD Card..." text up in the status bar appear, but then it disappeared quicker than it should have. I opened up 6 file managers (ASTRO, OI, CM, Root Explorer, AndroZip and ES File Explorer) and tried to access the extSD directory, but it always shows up as empty; not even a LOST.DIR existed. Nothing could be copied to the extSD directory.
Then I plugged Card A into my PC, and checked the filesystem. It turns out that the card is formatted to exFAT by default. This isn't what I expected, because:
1. exFAT is a licensed proprietary filesystem, not supported by Android due to licensing
2. Only Samsung's newer devices (i.e. Galaxy S3, Note 2, Note 10.1) have partial unofficial exFAT support hacked into their stock TouchWiz ROM
3. Samsung's newer TouchWiz devices do not constitute for all "Android Smartphones", as SanDisk should know
So then I tried to copy a few videos to Card A. But only one video could be copied, then the card would unmount itself. Physically reconnecting it mounts it again, and performing no operations to it will leave it mounted. But as soon as I try to copy again or run a CHKDSK, it would unmount.
I opened up EASEUS Partition Manager and saw that Card A had two partitions - a large ~59.46 GB partition, and the dreaded unallocated 16 MB known to plague SanDisk's 64 GB MicroSDs. I formatted the large partition to FAT32 with a 8192kb cluster size, and the same aforementioned problem still occurs. I sent this card back for replacement, and am still awaiting news on it.
Card B is quite interesting. I plugged it into my computer, everything seems fine, so then I try it on my Asus Slider. Surprisingly, because it is an exFAT volume, the Slider detects it perfectly fine - correct capacity, LOST.DIR exists and I can perform file operations on it. I copied 30 GB of files onto it with no problems. The problems arise when I format it to FAT32.
(Note: My Asus Slider is running stock rooted 4.0.3 and it can natively read FAT32, exFAT and even NTFS. The single USB port it has can also operate a 2.5" NTFS external hard drive running off USB power.)
Card B also has the mysterious 16 MB unallocated space. This time, I deleted the exFAT partition (instead of directly formatting it to FAT32) creating one large unallocated space, THEN I formatted it to FAT32. I copied the same files to it, and it didn't unmount like Card A did.
(Note: My Galaxy S2 is now running Vanilla RootBox v3.8)
I try to use Card B in my Galaxy S2, and it hangs on the RootBox boot animation. My Slider shows "Preparing External Storage..."
, then quickly disappears, much like Card A did on RR 3.1.2 as previously mentioned. It boots again if I use my 32 GB SDHD MicroSD.
Card B still reads fine as a FAT32 volume on my PC. No sudden unmounts or anything.
And all that brings me here, seeking help from the almighty XDA Forums. Does anyone have any idea why this is happening? How can I get it to work on my Galaxy S2?
UPDATE: My replacement card seems to work without problems. Statistical chance of card failure is now 66.67% instead of 100%.
2nd UPDATE: My second replacement also seems to work without problems. Statistical chance of card failure is now 50%.
I can unfortunately not help you but can sympathise with you. I had similar problems with a 32gb Sandisk card. I do not have such a well documented description of what I did but can say that folders and files simply disappeared from the card after a short period of time!!
A folder containing one short film clip and about 40 photos was first visible on the phone and disappeared after a few hours. I had time to see the film on my phone, take and save a few screen shots from the film and view all the pictures. The next day they were gone. I reconnected to the PC to find no files or folders. The screen shots were still however on my phone saved on the internal memory. Other problems had to do with first being able to save photgraphs taken with the stock camera to the sd card and then not being able to.
Searching here and on other forums revealed that many had similar problems but no solutions.
I eventually asked for advice from a PC hardware store that recommended I ditched the Sandisk card and buy a Kingston, which I did, albeit a 8 Gb.
No problems since then.
Ask amongst your friends if they have a none Sandisk card you can try.
Good luck
Have you tried formatting the card in Recovery (TWRP or CWM should do the trick) or are you formatting with your PC? Also, does the card plug into your PC or are you using the phone as a reader plugged into your PC?
@ vantt1
I had very similar experience to you with two of exactly the same sdcards and I do not believe a solution exists. In short, return them, get your money back and try a different brand. I have since stayed away from SanDisk.

This is the first time that I've had any problems with SanDisk. I also have two 2 GB, a 4 GB, 16 GB and a 32 GB (which I'm currently using in my GS2) which all work perfectly.
I use an internal card reader in my PC, and recovery can't detect the 64 GB MicroSD.
Can someone please confirm if the Galaxy S2's newest stock TouchWiz supports exFAT?

I'm wondering if your S2 is an original/older S2, maybe a later S2 would recognize the card. This sounds like a hardware issue if Recovery isn't recognizing the SD card.
Some other things to consider which "flavor" of S2 you have verses which "flavor" others have who make their 64GB work. By "flavor" I mean the i1900 and i777 and i727 (I think that last one is right). They are all classified as S2s but they all have slightly different hardware builds. I would venture to say the 2, 4, 16, and 32 all work perfect because the S2 was designed with those cards in mind.

Mine is the GT-i9100.
You have to format the card as Fat32 and know that you will lose about 4-5GB of space. Fat32 has some unique sectoring practices.
Samsung also, doesn't/didn't utilize the XC format (a format that was more mainstreamed utilized after the S2s came out if I am correct in what I've been reading) whereas a pc card reader would have no problem. It's a hardware issue, not software.
Another consideration is where did you buy these cards from? You mentioned sending it back. How sure are you that they are legit and not fakes? Some people will buy a fake and never be the wiser. I realize fakes are cheaper alternatives.
At any rate, I hope this helps.

If you must know, I bought it from the Golden Computer Arcade in Sham Shui Po, Hong Kong (as there are many smaller shops within, I don't think it's necessary to mention the exact store for reasons). They got me a replacement card a few days ago, so when I have time I'll update my situation.
P.S. Hong Kong isn't like mainland China; if they say it's real, it is. Rarely do you find counterfeit products being advertised and sold as their real counterparts (unless you are a tourist). Being a local, I'd be able to tell if something is fake on first inspection from experience. (At least I'm pretty sure I can!)
I may finally have an answer of sorts for you to try. But, don't blame me if you jack up your phone.
Utilizing the app Root External 2 Internal SD you may be able to trick the GS2 into using your 64GB card as the INTERNAL memory and the current 16GB internal as EXTERNAL.

It doesn't seem like a practical solution to my problem, and I don't think it will work given the card is dead already.
I just received my replacement card today, and I deleted the exFAT partition and created a FAT32 one. So far so good; my Galaxy S2 detects it and under storage settings it says 59.46 GB as expected. I am now in the process of copying the contents of my 32 GB card to my 64 GB card.
Looks like this one might be a keeper. 27 GB of data was successfully copied to the card, and my Galaxy S2 can read it fine. I will do some speed tests later when I have the time and update when necessary after using the card for a while.
Seems alright. Is the 30Mbps speed the total read+write speed? If so, 7.3+21.1=28.4 which is good enough for me.
The internal memory's read speed is super fast for some reason, but the write speed is slower. Class 80, maybe?
My second replacement card arrived yesterday. It works!
i solved
i have a similar problem too...
i have a new 64gb sd card an i try to copy file (about 20 gb) on it.
i notice that some file 'disappear' in few minutes makes folder empty.
the problem was the usb micro sd adapter i use for connect sd to my pc... it's too older (or the sd card is too big)... the adapter works fine with my old 8-4-2 gb sd card but with this 'big' one it doesn't...
i try to insert the sd card directly in my smartphone and transfer the file on it by its usb cable and it works!
hope this hint may help you.
Have a nice day.

I was given one of these cards as a gift and the first one shipped failed to format but the replacement came in today and works great in my Galaxy Tab 7 Plus. Just thought someone may want to know. The formatted storage space is 59.4gb.
ZOMG. 64gb works with the GTab+? that's legit! how much did you pay for it?

It was a gift but Amazon had it for $149.00 at the time.
You are so lucky! If it were about 75 bucks I would actually consider getting of of these...
I'm planning to buy this card,so i want to know its actually transfer speed. Can you test it on PC using the software Atto Disk Benchmark ?
Since they started doing this "internal" and "external" memory card with our devices, I'm not too worried about swapping the sd card in and out anymore as it doesn't affect the way the device works as much as it used to.
I have a 32GB card each for my tablet and phone that pretty much stay there all the time. What i did instead for extra capacity was collect all the old 16GB cards and store them in this sd-card holder that fits perfectly in this black aluminum business card holder. I bought the sd-card organizer and business card holder from ebay.
That's 11 (one in the microSD to SD adapter) 16GB cards for 176GB total. I mainly use this system to backup and transfer pictures from my bigger SD cards when I'm out shooting photos (using the 30-Pin to SD adapter).

What did you use to format the card? i put this in my G Tab+ and when i click mount sd, it gives me an error icon in the notification area. when i tap that and click format, it says it is blank or has an unsupported file system. Any help would be appreciated
*Edit* - I've been having trouble finding a utility I trust to format the card as FAT32. On my windows 7 64 bit machine, the native right click format menu doesnt even give me the option of doing FAT32, just exFAT or NTFS (both useless for the application I need). Even the official SD Formatter tool didnt give any choice in the filesystem to format to.
After seeing this article, I decided as a last ditch effort to use my Vibrant to see if i could get it to format as FAT32 since the article mentioned it working in the Galaxy S. This worked and i now have 59.4GB free to exploit on my G Tab+ (However, I did have to use the file write permissions fix to get things to copy between internal and external memory within Astro). Just wanted to post for others that were having trouble finding a way to format this card as FAT32. My assumption is any of those confirmed devices will format it.
Hi, I have now gone through 2 cards, the first one thinking it was broke so i sent it back, and my unit is doing the exact same with my new card.
When i got my first card which was a sandisk ultra 64gb sdxc card, i thought it was originaly a bad card as my unit wouldn't see it, plus when i put it into my laptop and formatted it, it only showed as 32gb.
i exchanged that card for basically the same one, but it said made for android on it.
I put that straight into my unit when i opened it and that said the same thing on my unit, can now safely remove card, and when i went to settings > storage, there was no sign of a card, it just said mount card, and if i did this, it would say preparing card then a little after say i can safely remove it again and still show nothing.
i have now put this card back on my laptop and formatted it as fat32 (as i thought this one was going to be already seems it says its made for android devices), and again, it shows on my laptop as only 32gb and not 64gb, the file system is fat32 as well.
i have seen screen shots of people using this card in a 10.1 and their storage does show as 64gb.
i have tried using hp format utility and guiformat to format as fat32 (both show on unit but only as 32gb), i have tried using windows 7 formatter to format as exfat (which wont show in my unit), i have also tried sdformatter 3.1 which also doesn't seem to get my 64gb to show.
can anyone help, i surely couldn;t have got 2 bad cards?

Why are you cross-posting James?
lol i wasn't sure how fast i would get an answer in the other forum so i posted to both
thank you very much for your help though
What was the solution?
Edit:found the other thread
well the solution for me was to get a 32gb card as i just couldn't get a 64gb to work, i have not had the latest update either to test out a 64gb card.
Easius partition manager to format 64gb card FAT32... This will allow you to use the sd card until you get the update, it just means you're restricted to 4gb files and under....

I tried the H2TestW... when it opes it also only says 29 GB.
But when it was first seen by me it showed 64 GB with exFat format. Only upon using programs such as guiformat... to format it to FAT 32 it changed to the lower value.
Try formatting ntfs
Does the Note support 64GB cards? The Samsung Uk site states "up to 32GB". If anyone should manage to get it to show full 64GB, please share as I'm wanting to buy a larger card.
64 GB Card on Note 10.1
I am running a Sandisk 64GB SDcard on my Note 10.1 and it works fine.
I did install it...unmount it, format it and rremounted it.
It is a Wifi GT-N013 and the card worked under both ICS and JB.
Hope it helps

Hello all,
I have a few questions regarding the T699...
Just got one off eBay, and I'm noticing my 64 GB microSD card is causing problems. Not sure if maybe the phone only supports 32GB and I have a problem, or what? I've noticed that when I try to install things via CWM it has issues off/on. It'll go partially through an install and then complain that the file is bad -- CyanogenMod (the latest release from this month that was marked SNAPSHOT) was also constantly mounting/unmounting the SD Card back and forth. I'm thinking it could be the card, but I'm not sure.
CM was also crashing on Trebuchet and a few other things... so I kind of convinced myself it was that.
It *could* be the phone -- but I'm not sure -- I just wanted to ask here and hopefully get some answers beforehand.
Sorry, I hate to double post, but I feel this is important and worth double-posting...
So, I've noticed that it doesn't have external or internal SD card slots right. The internal SD card seems to have another folder, "0" that it creates that it accesses, and the external SD card slot isn't working/showing up. Seems like this all happened with Jellybean...
Any thoughts/changes/adjustments?
The relay has a micro-SDHC card slot, which only supports up to 32GB. Apparently there's hypothetical backwards compatibility from SDXC (64GB and up) to SDHC (https://en.wikipedia.org/wiki/Secure_Digital#SDXC It's on the internet, it must be true...), but I can't say whether the Relay supports this, as I've never tried it. Considering your experience, probably not.
Regarding internal vs. external, the internal sd has always been the primary on the relay. The internal sd seems like it's supposed to be mounted as the folder 0, and it's also mounted in a few other spots (/sdcard, /mnt/sdcard, /storage/sdcard0). I don't remember when I first noticed the 0 folder showing up instead of just /mnt/sdcard, but it still seems to work just as well. The external, if it worked (which it does for me), would be mounted as /storage/sdcard1 /mnt/extSdCard and /extSdCard (it doesn't seem to create a folder just named "1" anywhere).

Other posters on the web (from what I've seen) said that the Relay supports 64GB... and have successfully done it with my card, I believe. Maybe I should try a 32GB or smaller and see if it works without any issues? I have a Captivate Glide, which is an older phone, and it supported it just fine. But I think there is something weird going on with how things are being mounted in the system...
I had no luck with my Sandisk 64 gig card. It lives in my laptop now.
It's a good card and it's not a fake. I'm savvy enough to use good hardware.
I gave the 64 gig a spin with stock and CM ICS and JB. No luck.
It may work on some devices--provided you get a genuine card with a quick transfer rate. But, it sure doesn't work for mine.
My advice is to backup all your data and keep a 32 gig card handy. My 64 gig eventually ended up being one big LOST folder.
It works great in my laptop, though...

Wow. I google'd and found a few reports of folks who had them working. And mine worked great in Cappy Glide.
I did find a Class 6 16GB from my Sammy Epic and that seems to work great and without any issues. I guess that's where to go from here!

How much space are you using on it? Some folks are suggesting it only works/supports 32GB -- but will DISPLAY the full size. Have you bothered to go over 32GB in data on it? Supposedly THAT is what causes it to have issues -- also what ROM are you on?

As a follow up, I just filled up my SD card twice, no problems.
For me, files and folders mysteriously disappeared (wished away to the LOST.DIR "cornfield"..) over the course of weeks... So, I wouldn't expect to immediately experience anything out of the ordinary.. Rebooting the device often seems to accelerate the process..
Anyhow, if it works for your device that's a great thing. Additional storage is always welcome.
I'm wondering if you're having the same problem as I had on the one I returned. Did yours randomly reboot? Files went to zero byte size?
It happened on mine, tried two cards, a G-Skill 8GB and a Kingmax 32GB. Both cards worked fine on other phones.
Did a few Google play store app updates this afternoon. Then decided to restart the phone. The phone no longer recognizes my SD card. Any suggestions?
Never seen a device do this. Tried other micro SD cards I have and the phone recognizes them fine. Tried my 64GB card in the computer and it sees all the data on the card. Stumped on this?
I notice my other SD cards are formatted as FAT32 and my newest 64 GB card is an exFAT format, but it's read it fine up to today?
Have u tried formating it to fat32.
Did the problem go away?
Wouldn't format to fat32. I ended up moving all my data (files, videos, photos, app data, etc.) Over to my computer, then I reformatted the SD card and moved all my data back. Phone reads all the data fine now, but I had to reload all my apps that I had running of the SD card. What a PITA!

I had this problem with a couple of sandisk 64gb microsd's while I was out of town....the only solution I found was finally to use an adata one...and I'm now using a samsung 128gb. I tried formatting it on a linux pc and the phone...it did not like the sandisk's and would eventually lose them. I did have some success in only formatting the 64gb sandisks to 32gb but I may not have waited long enough for it to get corrupted as my adata one was available once I returned home.

I had this problem with a couple of sandisk 64gb microsd's while I was out of town....the only solution I found was finally to use an adata one...and I'm now using a samsung 128gb.

I'm starting to have what may develop into the same problem with the Sandisk 64 gb sd card in my camera (not a phone) -- so maybe Sandisk is having some reliability problems?

It was very frustrating for me as the whole point of purchasing sandisk was based on their reliability. I was concerned about the samsung 128gb I picked up for $69.99 but it's worked like a champ and has fast read/write speeds.
Trouble with Samsung EVO 64GB sd card
My Samsung EVO 64GB only partially works with my 6045i. It shows as mounted but struggles to unmount. Takes 2 tries. When I try to have a 3rd party app use it for storage it doesn't show available even with show SD card enabled and use Android 5 Storage Application Framework (see the attached screenshot).
I grabbed two other microSD cards, one Sandisk and one Patriot (Class 4), both 32GB. Both worked flawlessly in my Idol 3.
So now my son's Galaxy S3 is using the 64GB Samsung card (he's running CyanideL) and it appears to operate correctly.
I'm ok with using a 32GB for now, but what other cards are folks using for either 64 or 128GB external storage?

I also own same Samsung 64 gb microsd card. However, i can get access from 3rd party apps, but suffer from random cuts while playing music, seems media app issue.
Problem was firmware not microSD issue.
I have both a Sandisk and Samsung 64gb and they both have had the same problem that every once and while the phone will reboot by itself and when it come back up I cannot access SD card. I have taken it out and I can see all the apps, music and videos are still there on my computer but in the phone nothing. I have to save, reformat and re-download apps.
Anyone have a 128GB card fully working?
So the 64gb Samsung EVO died in my son's S3, so I gave him the 32gb one that I was using and sprung for a 128gb SiliconPower card, rated at up to 75MBps.
I can get the stock camera to save photos to it but when I try Open Camera, it isn't seen. I have storage access framework enabled in OC. I get the attached screenshot. Note that I do have "show sd card" selected. I can toggle it on/off with no visible change.
Its not just Open Camera either. Another app, Solid Explorer, has the same issue if I try move any photo files through it, it asks me to grant permission, shows the same window as attached, and then can't complete because the OS isn't showing it as available.
Any thoughts? Is this a bug in 5.0.2?
thanks,
I got a 256GB SD-card recently. Only after purchase I bothered to check the phone specs, which clearly states that 64GB is max supported card size. Stupid, I know.
The phone sees the 256gb card, is able to read-write to it, but otherwise acts weird. Data amount saved to the card changes on every reboot, number of songs downloaded to card varies on every reboot. Either the card is faulty or its simply too big.
Noob that I am, couple of questions:
1) provided that the size is the issue, is using multiple partitions (eg split the capacity in two 128GB parts) worth trying?
2) are there differences on various ROMs on how they handle large capacity SD-cards? Currently running ResurrectionRemix 5.7.4-20161113 (Android 6.0.1)
Thanx and have a good one
SD cards support is more a matter of hardware than software. Otherwise even 2010 smartphones could run 256 GB SD cards.
I would say the card is faulty, since the phone wouldn't recognize it if it were to not supported. But don't take my word for it.
The reason why the S4 has the max capacity listed at 64 is because, at the time of its release, the biggest card was 64 GB.
256 gigs is way too high like Ow said.
Go with a type 11 64 gig memory card, I'm using a 32 gig type 1 and have to deal with errors constantly.
Partition it 4 x 64Gb using Minitool Partition Wizard.

It's likely a software/ROM issue as a friend of mine with a Note 2 has a 256GB MicroSD that runs perfectly.
The SDHX standard on the S4 can support MicroSD cards of up to 2TB theoretically.

Kernel issue?
Try a kernel that supports exfat. I have one on an S3 mini running CM 12.1, and I am using a 128gb microsd with no problems.
Can anybody confirm a 256GB card works? It should since my 32GB works as exFAT and if the last post says 128GB is also working, that would suggest all sdXC would work, no?
I got a 128gb (micro sdxc samsung evo plus) on my galaxy S4 I9505 and runs like charm.
I'm sure if it was 256gb would run with no problems as well.
So the problem is not the card capacity, that's for sure.
