Noticing that the Nook HD+ manual states that the Nook (hardware + B&N software) supports up to a 64GB uSD card, I decided to upgrade my HD+ running CM-11 (running the 2016-08-15 nightly) to a SanDisk 64Gb uSD card. I formatted it (exFAT) on the PC and (on the PC) copied the old 32GB (FAT32) card to the new one, and inserted it into the HD+. It did not work (readable but errors when writing).
However, by accident I inserted a 32GB card freshly formatted for NTFS, and noticed that CM-11 created a LOST.DIR directory, indicating that it recognized and accepted the NTFS drive.
To make a long story short, after some testing, I reformatted as NTFS the 64GB card, and copied my previous uSD card files to it. It appears to work fine!
I assume that this is a CM-specific feature, and that regular Android manufacturers are sticking with the exFAT support for larger uSD cards.
Hey Dean o/ I recently resurrected my HD+ and tried out all the CM ROMS 11-14, and didn't have any trouble with an empty exFAT 64GB card. It could be that something coincidentally got corrupted in the first transfer. I did have to reformat my card in Windows after downgrading from Marshmallow/Nougat to Lollipop, after letting the newer systems link the card to internal storage. CM 12.1 wouldn't offer to format it for me.

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!

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:

I am having some trouble with one of my MicroSD cards. It's a Patriot Memory MicroSD HC Class 10 32 GB card. The card is formatted with FAT32.
The card is recognized and works just fine under Android. However, when I go into recovery, the card won't mount.
I have the same issue with TWRP (under several versions, such as 2.4.4.0 and 2.6.3.0) and Thor's Touch Recovery 1.8.1 (CWM 6.0.3.7).
Does anyone have any idea what's going on?
I'm not quite sure what's going on. I purchased a brand new Sony 32gb microSD card and it works fine in both Android and recovery.
It seems like it has something to do with formatting the card... I also have a Patriot 16gb card that was working fine, but after re-formatting it (still FAT32), it no longer shows up in recovery.
I've tried formatting the non-working cards several ways... Standard Windows formatter, GUIFormat in Windows, even formatting from Android.
Hi all,
So my SD card recently kept unmounting itself from my phone, and I've been allowed to get a full refund as it's a known compatibility issue with SanDisk cards and S4.
The problem here is that I cannot format my card using most means (through PC, MAC, Phone, and DSLR). The card is currently using exFAT. It mounts to my system fine, I can see all files stored perfectly, although whenever I delete the files individually and remount my SD card, all the files appear again!!
Through PC, I have used Disk Management, EaseUS Partition Manager.
Through MAC, I've used Disk Utility, SD Card Formatter v3.
At the moment, i don't feel comfortable in sending it back, with personal data easily accessible.
Anyone have any other methods / ideas?
Thanks!
GUIFormat ?
Same issue here. if anyone finds a solution pm me or reply
Sandisk messed up and make faulty card. It seem this only happened to 64gb SDXC card. I already had mine replaced under warranty 1 time and then after a while it's acting up again. So I ditch that card and buy the other brand.

Hello everyone,
Recently, I flashed a Lollipop ROM to play around with it. This isn’t about the ROM or the Android release in particular. It’s about filesystems.
While Lollipop worked perfectly fine with my external SD, the OP mentioned reformatting the SD Card as a different filesystem to play nicer with the new release. The other benefit of doing this would be support for >4GB file size, which is what I want. I've meant to do this for a while, but I've been too busy.
I’ve since reverted back to 4.4 while I wait for a more preferable Lollipop release to bake, but I still want to reformat my external SD. It is 64GB and I’ve attempted to reformat in TWRP, using a USB SD reader using OS X Disk Utility and a built-in reader using Windows format tool.
Nothing works! TWRP says it formats successfully, but everything is intact. Windows gives errors, OS X can’t remount the drive and finish.
What’s going on here? FAT32 sucks and I want to change it. Is it a protection on the chip?

Cards over 32GB in size are supposed (as per SD-alliance standards) to be exFAT, stock Samsung ROMs WILL format those AFAIK to exFAT. With the card inside the phone no other formatting option (than from the ROM itself) will work. With the card taken out and placed into a decent card reader in Windows 7 or newer you should see the option to format it to exFAT, and all decent ROMs should now work with that (Samsung stock-derived ROMs work best since they have a very solid exFAT driver, CM-derived ROMs have been very ****ty in the past in this regard).
Oh, and one more thing - questions should go to Q/A!
Hi all,
I have a Galaxy S5 (SM-G900W8) Canadian model. I purchased a 128GB sd card and I'm running into some issues. My S5 can detect the card, and I can copy files to it. But it seems that one I hit roughly 8.08GB of used storage, anything more I add disappears after my phone reboots.
The card was formatted in FAT32 originally. I have tried exFAT but the phone is unable to read the card in this file format. I have also tried NTFS but same results as exFAT.
I have done some research and have seen others with issues regarding 64 and 128GB sd cards with Samsung Galaxy models, but no fix yet (or at least from what I've seen/read).
This card only seems to work in FAT32, but I am unable to use the full capacity of the 128GB sd card in FAT32.
I have a 32GB sd card that works just fine without issues. Not sure what file table the 32GB card is formatted in though as I did not know of this issue until recently when I discovered it so never bothered to check.
Is there a fix for this that I have not found yet? This is quite annoying.
Thanks
Probably a fake.
i dont have problem with Team MicroSD 64GB
you have to format it in your phone (ExFAT), use file explorer in your phone, do not format using PC

What sd card is this because it seems like it's a fake and may not really have all that storage. I've never had any problems with my 64 gb SanDisk micro sd card which I'm currently using.
try PC format

I downloaded the tool and just used the cleaner. I found problems and then I ran clean & fix and it seems to have solved the problem. Thank you very much.
