64GB MicroSD Card - The how-to guide!

As you all hopefully know, the Note Can take up to 64GB MicroSDXC cards. But, what you may not know is the trouble that with comes with getting one to work. Its actually relatively simple When you know how to do it. l spent hours tonight trying to do it.
Originally the sd will probably be in the NTFS format created by Microsoft, which is understandable since its the biggest OS on computers.
Upon entering your SD onto the device, you should see that it wants you to format it. This is due to android not supporting NTFS. The only structure it supports is FAT32.
But, here's where your options come in! You have the choice of either making your device NTFS compatible (Note that this requires root), or reform making the storage device to FAT32. As my device is not yet rooted to test the NTFS support, l will only go over the reformatting process. Unfortunately, since I'm a new member I can't post links. Therefore, you'll need to trust google to guide you to what you want. But if you want to use the tool I used just Google "Kioskea HP USB Disk Storage Format Tool"
Disclaimer: I take no responsibility for any damage that you Cause to your device, computer or SD card while carrying out this method. It is your own decision to do this. This method should cause no harm to any system health, but, as with anything on a computer, errors can occur. Also, take note that the more you format something, the shorter its life will be.
Insert your SD card into the computer to format it. To format to FAT32, you will need to download a third party partition program, as windows withdrew the ability to format to FAT32 in an attempt to push more people on to NTFS. Only storage mediums with FAT32 as their default can format to it.
Once you've downloaded and installed the software, load it up and select your sd card and FAT32, as well as quick format then start. You should then insert it into your PHONE as the tablet doesn't seem to do this next step correctly. When inserted into your phone, it should say that the sd needs formatted. Do this then eject it and transfer it to your tablet and say yes to the dialogue that appears. And that's it in a nutshell! This can be applied for every android device possible.

Users report the newer note 10.1 updates will format 64gb cards into exFat which will allow for files bigger the 4gb (like HD movies).

Yes, i can confirm that if you update to the pulled ota update firmware, your tablet can format the 64gb sdxc to exFat and be read.

Sandisk 64Gb microSDXC cards comes preformatted with exFAT and not NTFS.

Sent from my GT-N8000 using xda premium

I am using sandisk 64G sdxc card in my N8000 (Hong Kong version N8000ZSALI1 firmware) which natively supports exFAT format. It is fine so far. But I do not dare to copy large file from USB cable via Kies. I take out the card and put into SDXC card reader for large files copying.

Hi, I have some questions:
- What different between "HP USB Disk Storage Format Tool" and the Windows built-in format tool?
- Why your GNote 10.1 cannot format the SD card?

@Tubgirl my one came formatted with NTFS, rather than exFAT. So, I had assumed the rest were like this. It's strange that mine exFAT. :s

@Itchiee I'd seen reports of updates being able to support 64GB cards but that's all I was able to find. I only just got my Note 10.1 and it says on both the internal update and update via Kies that my tablet is up to date. Although, I am from the UK that may be why. I assumed my tablet was rolled out with the latest update. I tried exFAT on my tablet and it refused to work and was throwing the same error's at me.

@vndnguyen I recommended the "HP USB Disk Storage Format Tool" as compared to the standard Windows one as Microsoft pulled formatting support for anything except exFAT and NTFS. The only time Microsoft will let you format to FAT32 is if it was the native of that device, such as a flash drive. So, the difference between the two programs, is that the "HP USB Disk Storage Format Tool" can format to FAT32, as where Windows cannot.

I have just ordered a 64 gb sandisk android sdxc card, if i am not to bothered about transfering large files, is there much difference between using exfat and fat32?

I don't have 64G sd card. I have 8GB sd card and I can format it as FAT32 on my Windows 7 PC

This is because the native format of 32GB MicroSD cards and below were FAT32. Like I said, if the device is native FAT32, then Windows will allow a format of that.

Sorry for not replying in my last post. I never seen your comment. There's some slight differences between FAT32 and exFAT. The main difference a common user should know is that FAT32 can only hold, and transfer a maximum of 4GB, as where exFAT does not have a size limit. That's why it's the "preferred" method. But, FAT32 is more popular as it's been around longer and is supported by more platforms than exFAT. If you want to know more about the differences, try a google search. Unfortunately I can't post links just yet to help you out with that. But, I'd recommend trying the exFAT wiki page. The stuff you'll find can get fairly technical. Just a heads up.

thanks for your reply, the sandisk card i am getting says its been made for android devices, will that means its probably already in the exfat format when i get it?
Would you know if the below card which i have ordered would probably work straight out the box?

This is the one I got and I had to format on my Defy first. Then my tablet excepted it, for now I can only put movies, photos on. Any apps you want on doesn't work as of yet which was a big let down for me.

This appears to be the same one that I ordered. Mine came as NTFS but it may have just been a hiccup for mine as everyone else is apparently exFAT. One thing I also noticed is that the page says it is both class six and class 10. Just to clarify - It is class 10.

Jayjay, there are apps that that allow you to do this. I would recommend trying App2SD, Link2SD and Directory Bind. DB can be found by searching the xda forums.

Yeah some require root. I tried some today, as well. They don't work due to the memory config. Seems to be happen to all new releases, as if they're trying to block stuff like that. With all the trouble Google and manufacturers are going to to stop us rooting and stuff like that, Android will soon be as non-combustible as iOS!

This is because Samsung claim that their Note 10.1 can support exFAT. In reality, the support for it doesn't work at the moment. What you will need to do is reformat it to FAT32, and it should work. If it still doesn't work after this, put the SD into your mobile phone then use the reformat option on the phone. The reformatting does not work on the Note 10.1, so you can't reformat it on that.
Let me know how it goes.

Help with 64GB SDcard

Just got a SanDisk microSDXC 64GB card from Amazon for my Galaxy S4. I don't want to mess anything up, so I've got a few questions.
Are these cards formatted with exFat? How can I tell? Do I need a special kernel to have it work? Will the stock kernel work?
Should I format it from within the phone before use?
Any other problems/concerns I should have before I copy all my music and ROMS over to the card?
Thanks in advance,
Foulwx...in Atlanta tonight where there really is some foul weather.

I recently purchased a 32GB SanDisk Ultra, and followed the instructions at these two links, for moving apps to the sd card:
http://forum.xda-developers.com/showthread.php?t=2142844 - mini partition tool guide
http://forum.xda-developers.com/showthread.php?t=2285221 - link2sd and foldermount
If you have some way to connect the card to your PC, the mini partition tool guide is really easy to follow. If you don't plan on moving apps to the card, you could just toss it in the phone and format it there. I screwed up the partitions a couple of times on my own (formatted the card 5 or 6 separate times, trying out different filesystems and partition sizes), before I found the mini partition tool guide, so I don't think there's much chance of permanently ruining the card.

If you formatted the card into fat32, then it would be more compatible without modifying anything on the phone.

You can connect the microSD to your PC to determine what format it currently is. If you stick in the phone, it'll format to exFat. The exFat format can be recognized by the stock kernel as well as the agat kernel and the ktoonsez kernel.

I have the same one. Just put it in my phone and went from there. Guess it auto formats it to exfat that way.
I flashed bluKuban and had to switch to agats kernel to see it. But otherwise works well.

exFat can have files over 4gb.

I killed my sandisk 32gb ultra card ...created the fat 32 partition and then the exfat and it won't be ready by the phone at all. When I put it into the computer it shows it only has 30.6 MB...I'm unable to format it through windows or with another app. Any help would be appreciated

Insert it into your phone, and format it there. That "may" fix it for you.

Its not being read by the phone it doesn't even mount..

I'd try plugging it into the computer and running a partitioning program. It should see the card no matter what. Partition it to whatever format you want.

Theres one computer where it sees it and I connect it through an HP printer that had an SD slot.. Windows shows it as 30.6MB and asks me to format it but the format fails. I tried SD card formatter, HP USB disk tool..I don't know what to do

OK, I loaded all my music, pictures, and roms onto my 64SDCard from my laptop. Windows says it is exFat. Booted and seems to work fine.
Then I went into OUDhs recovery to try and make a nandroid. It can't mount the external_sd. Suggestions? Do I need a different recovery or kernel? I'm on the stock kernel.
Thanks again.
Edit: I installed TWRP 2.5.0.3 and it worked fine, I think. I haven't tried a restore yet.

I finally gave up with exFat and, after some research here on XDA, used Mini Tool Partition Wizard Home Edition to format my SDCard to fat32. I just made a Nandroid with OUDhs recovery. Hopefully, everything will continue to work OK and I don't need any 4GB files on my card.

[Q] MicroSD card problem

Hi guys,
I hope you guys can help me with this issue i'm having as i cant find any answer from searching here nor google.
Basically i bought a Samsung micro SD card that is 64gig (from Dustin.se which is a big company so i'm sure its no fake or anything) and the first thing i did was to format it to exFat using my win8 pc. But no matter what i do the pc see the card as 26gig!!!
I even downloaded a format program from
https://www.sdcard.org/downloads/formatter_4/
Now when i put the card into my S4 it sees it as 26gig which i formated but if i do a re-format it shows as 59gig (or 64gig in reality).
So i know the card is 64Gig but the question is why cant i format it using my pc?
And to make it even more strange when i take the card from my S4 back to my PC it wont recognize it, it wants to format it again. This happens after i format the SD using my S4.
Any idea why?
Basically all i want is to be able to use exFat (for big files) and be able to use the SD card both on phone and PC. Can someone please help me and tell me what i'm doing wrong?

Sounds like a fake or defective card to me. If windows will not see the entire capacity the chip has problems.

I actually got 2 of them and as i said this is the real thing. I reported the first one as bad chip since 2 times i got "corrupted SD" card from my S4.
But now when i test both of them on PC they behave the same. And i actually think the problem with my first SD is the phone that corrupt some files (just a feeling) since it works fine when i restart the phone.
Any other ideas? (i tested on my Macbook and another PC win7 with same result )
Do you have an 64gig card? if so did you format it using pc? and have your tried to format using S4 and put the SD into PC? did it work reading from it? What was the format S4 formated (Fat32 or exfat)?
ps. i run stock ROM so no root or anything.

When you have the chip in the PC right click My Computer/Manage/Storage/Disk Management then find your chip on the bottom, right click on it, then delete the partition, form a new one then format. Check and see if the proper storage amount is there after. I cant see the phone damaging the chip but who knows anything can happen.

Are you running xp? (Edit Sorry now I see you aren' t. Card reader? ) Older versions of Windows only have ability to read sdhc as opposed to sdxc so have problems with cards over 32gb (max for sdhc standard)
If so borrow a newer pc. The card probably was exfat from factory though. I've a 64gb card from Samsung as well (fat32) and had the corrupt message a couple of times. Fixed with remount.

Samsung 64gb user here. No probs at all. Formatted it once on my phone when i got it.

As you saw i tested on windows 8 and 7 so dont understand why it dont work
And as you say a remount fixes the corrupt problem so i dont think both my cards are fine but cant understand why i cant format them on my pc....
I want to be able to pop it out from the phone and copy/paste but as it is now when i format it on phone it gets unreadable on the pc which is also really strange. .

Ok i figure it out, i was to tired to think last night
The conclusion is that my microSD converter was obviously not compatible with the SDXC i assume, i had 2 usb stick that take the micro SD but when using these on my windows8 they were both detecting wrong. I had also a coverter that is in the form on regular SD card so when i use this one and put the micro SD in my laptop with buildin SD reader i see the 64gig right away and can also read the memory when i take it from the phone. So all works now.
I need to find a USB stick converter to be able to use it on my big PC
Thanks for the help guys.

Can't use new MicroSD Card

I have a 16GB microsd that works no problem, but I'm trying to upgrade the storage size.
I tried pretty much everything to get this new microSD card working, but nothing works.
I tried both a Sandisk and a samsung, they work on my girlfriend's phone no problem (LG G3).
I can't mount it, it tells me that the SD Card needs to be formatted. It won't format on the phone, and I tried formatting in windows several times but nothing works.
I can't help but feel this phone is defective, or is there some special way I should be doing it?
Thanks

Format the card to NTFS then inset into your phone. It should work. If not, format the card to FAT32 then do the same thing. There's no real reason this should be happening to you

Micro SD card wont be mounted by Samsung Tab a6

So I have a Samsung Tab a6 7 T280 wifi and I've inserted a MicroSD card (128GB). I've done this with the stock os first and I just got the message card can be removed safely. and it wouldn't let me mount it.
Now I've installed the Tinker V5.1 Stock Rom over it and it still happens. (wanted a faster os on it).
I can reformat the card with twrp to be ext4 or exFAT and it doesn't change a single thing. if I insert the sd card I get a quick preparing card and then instantly the message card can be safely removed. clicking on mount sd card in storage from settings doesn't do anything except prompt same message.

I'd try a different sdcard.

Okay, so I hope I can help, I have the SM-T280, I do not use Tinker ROM, instead I debloated my stock ROM and use an SPA kernel by @_mone. If you're trying to extend storage to your tablet, you'll need to use a PC to partition the SD card two PRIMARY partitions. I used on Windows MiniTool Partition Wizard (free), and I used a FAT32 partition and an ext2 partition. With the stock ROM/kernel I had problems using ext4 or extFAT which didn't make sense to me but it is what it is, and I used the app Apps2SD to handle all the work.
The main thing, you need to make sure your SD card has TWO (2) PRIMARY partitions.
Good luck.

FAT32 is not for large capacity storage. Use exFat. There isn't much point in having such a large ext2 partition. It's incompatible with media transfer protocols unless you use a Linux system.
This device fully supports exFAT. I use a 64gb sdcard no issues.

I wouldn't think so, I'm sure it supports 128gb cards.
Just partition it into to halves. First partition exfat. Leave the other unformatted and see what happens.

partitioned into a 40 GB exFAT partition and left rest unpartitioned. Didn't change anything. if I pop it in the tablet I get a short preparing sd card notification then immediately an SD card safe to remove notification...
I'm really confused by this. The tablet is new so I doubt that it's broken but I don't know. Do you know if there's a way to check any kind of logs on Android like dmesg on Linux as an example to see what happens with the sd card?

According to Samsung, the T280 will support a 256gb SD card BUT I know from experience that SD cards over 32gb can be VERY touchy. If you use a PC to remove all of the partition and then let the tablet try to do its own formatting and it still doesn't work, I'd say you have an incompatible SD card. That doesn't mean the card is bad but that it just won't work in the T280.
As an example, a Samsung EVO+ card (which can be found on eBay for $30) will probably work while a "no name" card from China, probably won't.

I always use Samsung EVO cards and they always work perfectly. Price per GB they are very reasonable too.
