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.

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?

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.

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.

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.

when i put the sd in my laptop,the 2 options that let me choose is ntfs and exfat.how can i reformat it to fat32?
Hi guys,
I faced a problem with my 64gb. Sandisk micro SD and I solved the issue and I thought about posting the solution here that might help some of you.
so... the issue I faced is how to get TWRP recovery or CWM to mount my Ex sd card.
basically the problem is that the card is formatted in exfat or NTFS and in both ways it won't be recognized by TWRP and the only way to formate it in fat32 is by only one software because windows can not format more than 32gb in Fat32.
and here is how:
first: download EaseUS Partition Master Home Edition from this link http://download.cnet.com/EaseUS-Partition-Master-Home-Edition/3000-2248_4-10863346.html?tag=mncol%3bpop&cdlPid=10982635
Second : Now you can see a list of all of your hard drives. Note the one highlighted in blue on the grid. This is my 64GB MicroSDXC card in my USB Card Reader. Obviously the location of your card in the list may differ dependant on the number of drives in your computer
You’ll need to right-click on the drive in the list representing your 64GB MicroSDXC card and click “Format partition”
Third : You need to select FAT32 for the File System, and 32KB for Cluster Size.
EaseUS doesn’t immediately apply the changes you specify. Instead, it queues them up so that you can review and revise them before you commit to having the program affect those changes. then we need to press the Apply button.
that's it ... now you can enjoy your 64gb MicroSd and you can mount it in TWRP or CWM recovery .

I've tried this method, my card became 32GB
Then I put it into my Galaxy Note, it saw it also as 32GB, then I formatted the card with Gnote, then it became 64GB again
I was planning to create two partitions with minitools formatting tool, one was supoosed to be 16 GB FAT32 and the remaning part would be 48GB NTFS, and I was planning to use, Paragon NTFS to mount that NTFS partition on GNOTE.
But because after formatting on PC it became 32 GB I couldn't do that.
Any suggestions ?
thanks so much for this. I just bought a new 64 gb card for my phone and it "corrupted" on me twice. I plugged it in to my comp and it was exFat. Followed the directions here and formatted to fat32. Now I have to copy my files again. I hope this works. Oh and according to my phone, there is no update 4.1.2 for it. I am on 4.0.4 and it cannot find any updates so that doesnt really work for me.
THANK YOU!!
I had been trying to do thiis for 4 hours when i saw ur post! Thanks sooo much..at first i got an error while formatting, but then i quit all other applications as recommended by the software and it woeked perfectly on my HTC Sensation. Thank You Soooo much:laugh::good:

No. Touchwizz roms and aokp/cm10 roms can both read fat32 sd cards. Because exfat is licenced from Microsoft AOKP can't incorporate the drivers needed to get exfat formatted card to work.
Short story is both roms can read/write to fat32 formatted sd cards. Only Touchwizz roms can read/write to exfat formatted cards. Unless you copy a lot of single files over 4GB in size stick with fat32 formatting.

You can still use your card normally. I've done the inverse way (Touchwiz to AOKP) and works too.
The point is: Touchwiz based ROMs have support to FAT32 and exFAT. AOKP ones have support only to FAT32.

That's another point OP have forgotten. Your card reader must support microSDXC cards. Most readers support only microSDHC and these are maximum 32Gb storage. microSDXC has elevated this limit to 2TB. I had to buy myself a new card reader due to that incompatibility.
There's a fragment in Wikipedia which explains this situation:
SDXC cards are pre-formatted with Microsoft's proprietary and patented exFAT file system, which the host device might not support. Since Microsoft does not publish the specifications of exFAT and its use requires a non-free license, many alternative or older operating systems do not support exFAT for technical or legal reasons. The use of exFAT on some SDXC cards may render SDXC unsuitable as a universal exchange medium, as an SDXC card that uses exFAT would not be usable in all host devices. Since the FAT32 file system supports volumes up to the SDXC's maximum theoretical capacity of 2 TB as well, a user could reformat an SDXC card to use FAT32 for greater portability between computers (see below). FAT32-formatted SDXC cards can be used in a host device built for SDHC if the host device can handle 64 GB and larger volumes.

I really sorry for my english, but I hope you and another people understand it. :good:
Ok, so I've just bought a Samsung class 10 SDXC UHS-1 card. I'm about to put it in the phone and then I read all about people having problems reading files, and wanting to download something to allow it to be formatted to fat32, etc. Could anyone please throw any light on this, as to how it it best formatted, and to what fat type, and possibly help me to understand why these people are having issues?
Personally I would have said let the phone format it, seeing as it's going to be using it?
1. Put it in the phone.
2. Press "Erase everything on SD-card".
3. ????
4. PROFIT!
No need to worry about formatting, the stock kernel only supports FAT32, and I believe EXT3 & 4, but you don't need to worry about those.
Some people have problems because they buy the cheapest 64GB microSD card available, and you know that cheap card = cheap NAND, which causes corruption of files and random unmounts.
You mean exFAT? That's what the phone formats it as, and the PC does too.
I am using exFAT because I put 4GB+ files there. FAT32 can't support that.

I did not know it had ExFAT, but I just put the card into the phone and pressed "Erase everything on SD card".
Well, I've put shed loads on it and no problems so far, and in my card reader I get up to 16MB/s write, so it's all good. I guess problems are just down to the people who buy cheap knock-offs?
I didn't even do a format on my SanDisk 32gb class10.
I just popped it in and it works.
Think I might format to exfat though so I can store larger files.

I got an S4 yesterday (USD 665 here in Muscat for the unlocked 16GB model) and put in the 64GB card I used before on Note II. It's formatted as exFAT.
On first power on, the phone complained that memory card was damaged and needed reformatting. Bummer! The S4 doesn't support exFAT???
I ignored the error and continued setting up the phone. After a few minutes I checked Settings->Storage and was given the option to mount the memory card. I tried and it mounted without any problems! Phew!
FAT32 is the way to go. Later, if you install a custom ROM exFAT won't be supported.

Not if you have files larger than 4GB, like full HD movies. FAT32 doesn't support files of that size.

I can confirm that my rooted i9505 (jfltexx from Vodafone Ireland) does support exFAT directly. I have a Samsung 64GB card which came preformatted with exFAT and it worked. I later formatted it directly in the phone and it was exFAT again. No problems whatsoever.
If you want to install a new kernel, however, you might get into trouble. faux123 wrote the following in his thread http://forum.xda-developers.com/showthread.php?t=2273437 for the new faux kernel:
"NOTE: This kernel DOES NOT SUPPORT exFAT formatted 64 GB SDCards! In order to use 64 GB SDCards, you need to format it to NTFS, then use NTFSMount from Play Store to access your 64GB SDCard.
(This is due to LACK OF SOURCE CODE from Samsung/Microsoft for exFAT. Samsung licensed Microsoft's CLOSED SOURCE exFAT implementation. But Samsung under agreement with Microsoft DOES NOT release the source code and therefore we CANNOT build any support for exFAT formatted 64 GB SDCards)"
I have the strangest feeling this has already been answered somewhere...but i've scoured the internet and havent found much of anything on the topic. I've read some mixed statements saying ppls sgs4 see's an external sd card formatted as exFAT, others say it isnt working for them. I've figured out a way to get the hardfloat Kali Linux ARM gui terminal working and all applications installed running in a chrooted environment...however the image size needs to be a minimum of 6gb to install all programs. I'd like to go with 8gb just to give it a little play. I have an SGH-I337 (AT&T) and am rooted, i've tried stock rom w/ stock kernel, stock rom w/ KTweaker kernel, said it supports exFAT but did not work. Also i've tried Cyanogenmod 10.1, but havent tried the KTweaker kernel w/ cyanogenmod yet. After formatting the 16gb microsd i have to exFAT and inserting it into the phone it states "Preparing SD Card"...and immediately says "SD Card is safe to remove". Anybody have any insight as to how i can get around this 4gb filesize limitation? Any input will be greatly appreciated. Thank you.
Here's the deal.
All cards 32gb or less (SDHC cards) come formatted in Fat32.(Part of SDHC spec) This includes a file limit of 4gb max for a single file.
All cards 64gb or more (SDXC cards which the S4 supports) come preformatted in exFat (Part of SDXC spec). This does not have a 4gb file limitation.
The stock Samsung / AT&T Firmware supports exFat. (I bought a 64gb SDXD formatted with exFat and plugged it in and worked right away). Most recoveries do to. (TWRP does at least).
However, I flashed CM10.1 onto my S4. CM10.1 does _NOT_ support exFat. Initially I backed up and reformatted my card in Fat32. Angry with the 4gb file limitation (I have many 720p and 1080p movies over 4gb..) I actually took the microSD card out, used a adapter and hooked it up to a Linux system (Ubuntu 13.04 in my case) and used gParted to format the card to EXT4 filesystem. EXT4 is a filesystem most Linux machines use and support natively. This is actually the filesystem most newer Android device use for their internal SDCard / Data partitions! I popped the card back in, CM10.1 reads it perfectly! And I was able to copy files over 4gb to the device!
So its not a hardware thing since the S4 is SDXC compatible. Just formatting / partition time issue.
I greatly appreciate the breakdown! However i do have a question, since the sgs4 supports exFAT, why does it not see it after i reformat my 16gb to exFAT? Is it because it is an SDHC and not an SDXC? Also, does the type of recovery you have installed alter what filesystem types are recognized?

No problem!
As far as the spec goes, if it's formated in exFatand its SDHC it should still read it fine. Filesystem is just a filesystem. The spec just says what is used by default on cards.
One possible issue though, did you format your card in your phone? Sometimes the odd way these work the SD cards like to be formatted in the phones themselves. It worked formatting from a Computer for my ext4 case, however that does not work for all cards/phones/filesystems sometimes.

I've tried formatting from phone, 3 different computers (one computer running Debian), cfdisk command line as well as gparted, also window's format utility. It seems though nothing is working however after going to Cyanogenmod 10.1 last night and formatting the external to ext4 the phone only displayed "Reading SD Card" then "SD Card is blank". It works perfectly fine whenever the phone formats it, it just doesnt like any other type of filesystem. It is a polariod sd card which gave me issues in the past. Hopefully i can get this resolved and post more on it. Probably just something small i'm missing :/
Anyways, thanks a million on the input!

Can you kindly link me/us to their (TWRP) posts verifying this?

As far as I know there aren't and posts saying it supports it but I've used TWRP with exFAT, Ext4, and FAT32 formatted ROMS.
roms not reading 64gb sandisk sdcard
I have the 64gb sandisk ultra class 10 sdcard... and it flat out works in stock... even when I recover. But doesnt work atall using wicked rom and a couple others. ExFat is the reason... those roms dont support it...
You can use this kernel to get exFAT support on custom ROMs such as Cyanogenmod:

Like alot of you, I recently had alot of trouble with my sandisk 64gb micro sd card. this fix is pretty easy but it worked for me! so check it out:
you need two programs: SD formatter( can be found on the sandisk website) and easeus partiton master( you can use any program that lets you format partitions)
you will also need the sd card adapter to put you micro in, and an sd card reader
Step 1: connect your sandisk 64gb microsd card to the computer with the adapter it came with in the box. My laptop has the sd card reader built in
I dont think it will work unless you connect it this way.
Step 2: open sd formatter, it should have recognized your card if not click refresh. after its recognized click Options and set format type to full (overwrite) format the sd card. this will take a long while so you might wanna go watch tv or something?
step 3 : after its done formatting open partition master and right click on the sd card and format it to fat32. your going to have to click apply on the top right hand corner for it to work
you should be set. DONT FORMAT IN THE ANDRIOD SETTINGS. for some reason when ever i fixed the micro and tried formatting it in my phone it would mess up everything thing again.
I keep a 32 gb in my s4 now and use my 64 in my note 10.1 because i need the space there more. Let me know if this works for you!

It really depends on the troubles you have, most of them are some kind of incompatibility with the S4 firmware and the 64GB SD card and formating this will not help. My issue was each time i'd put music on my SD, my system status would trip to custom, also my music would not always show up at boot. This has been a recurring problem with the sandisk cards no matter how i formated it. And yes, i did use SDFormater 4.0 and still had the issue. My only solution was to get a Samsung 64GB SD and no issues since
Sometimes mine removes itself, but a media rescan or reboot fixes it. Doesn't really bother me.
I use a 64gb PNY class10 and its flawless for me.I think the issue is witg the sandisk bran.

Figured this is a good thread to post my experience.
I had a MicroSD card I thought was bad. What happened was I was formatting the device to ext4 at the time using a older microSD USB adapter i had. Basically, the microSD card reader died while it was in that process. Using a microSD > SDAdater and a built in SD card slot on my laptop I was unable to format the drive in Windows or MacOS. (I was formatting the device via the USB reader on my Desktop in Ubuntu). Ubuntu does not see my card reader on my laptop so I was unable to use that). I thought I killed it. It was a SanDisk microSDXC 64gb card.
So I ordered a new Samsung microSDXC and a new microSDXC USB card reader. I got them both. New card worked great. I decided to play with the card a bit. Using Ubuntu, gparted specifically, with the new adapter I could no create or modify partitions on the old microSD card. It would fail out every time, different errors for ext4, exFAT and Fat32. So. In Gparted I went to Device > Write new partition table.After I did that I would able to format the drive in Ubuntu to whatever filesystem I wanted, and the card works in the phone, mac, windows, everything.
Just a heads up to help any others with issues. Rewriting the partition table may help if somehow it gets corrupt because of some write fail,
I ve 2 64gb sandisk 10x microsd with Samsung S4 I9005 with Android 4.3. I formatted with android, also Windows 7 64bit with various types of sizes on laptop. However on laptop or on phone after writing some files and disk scanning, it gives many disk errors. I wonder if it is software or microsd hardware problems. There is no problem with 32 gb.

Found the Culprit!
Considering I encountered this write protect error TWICE with the exact same product, and after having read forums that show it's a common problem, I conclude that the problem is with either this specific SanDisk product or a particular batch of this product:
Exact product specs: SanDisk Ultra 64 GB MicroSDXC Class 10 UHS-1 Memory Card with Adapter (SDSDQU-064G-AFFP-A)
These carry a lifetime warranty. A word of advice: if you go for a replacement, ask for a different 64GB model, or try a different size of the same model (I got 2 x 32GB cards instead). If they insist on giving back the exact same model, I'd suggest you use that card anywhere except a smartphone!
