I recommend using Fat32, because it plays the nicest with Android across the board. If it won't let you format to Fat32 on the device, use a computer to do so.

[Q] EXT2/3/4 for external SD card?

Can I pre-format the external SD card for EXT2/3/4 filesystem and use it in stock Note 2?
To format I can use a card reader and Linux desktop computer say...
Also what would happen with accessing such a card from PC (Windows, Linux?)
I think you can format sd card with phone itself if that's what you are asking.

Seems like the phone formats it with exFAT or FAT32 only depending on the ROM.
And the formatting is not a problem, I can always format from Linux.
The Q is how would the phone react? And what about accessing the SD from PC?
Well testing it yourself wouldn't hurt.

32GB micro SD card

Hey guys I recently purchased a 32gb SD card off eBay. Before I used it I formatted it to fat32 but it seems when ever I download a rom straight to the SD card from my phone it always get corrupts and stops me from doing anything in my recovery. I always get can't install <××××××> sdcard (bad) Aborted..etc. leading me to drag and drop everything to PC reformatting it. Anybody know I can avoid corruption. Thankyoi

What filesystem is it formatted as? And what version android are you running?
If you are running a cm based Rom and have your card formatted as ntsf or exfat, you will be having compatibility issues... I've never had much luck getting either of those file systems working with cm, even with the patches/fixes.
Try backing up your data from the sd and format in fat32 and see how it performs. You need a secondary program to format fat32, I use eas partition master, there is a free home version that you can get from their website.
Edit* here's a link to their site http://www.easeus.com

Using tw, intergalactic. Formatted to exfat. Always had problems with the big SD cards. So if I formatted it to exfat on my computer when I first got it, ran into problems and formatted it on my phone what file format does that do? Cause last night I formatted it on my phone because I'm in Ireland for a few weeks and don't have my computer.

I have (3) 64gb micro sd cards and (2) 32gb micro sd cards all formatted in fat32 and I don't have issues with any of them. The only time I've ever had issue is with my 64gb cards when I had them in exfat and then switched my tablets to aokp... that's when I found out that cm doesn't like exfat and ntfs. Since then, I've stuck with fat32 without issue.
I'm not sure what format android defaults to... though I believe it's exfat, whatever it is, it should be the most compatible considering it chooses that format. All my cards 32gb cards are Kingston and I believe my 64gb cards are SanDisk... it's possible that you have a bad card... a tw room shouldn't have any issue with exfat, only cm because they don't have the licensing for the format for official support.

[Q] How to use 64GB SD card in Tmobile Galaxy S4

I have tried to use a samsung 64GB micro sd card in my galaxy s4, but everytime i put music on the sd it says the sd is damaged and needs to be reformatted. I contacted T Mobile and they told me that their version of the galaxy s4 would only take sd cards up to 32GB. I have read some other treads on this site to try and get around this, like the exfat thing of fat32, both of which failed. I have recently rooted my phone, successfully, and i was wondering if anybody could help me get past this 32GB sd card only bs. Now that I have rooted my phone is there any option i can take to successfully have my 64GB sd work in my galaxy s4. If you need more information please let me know. I would like to solve this problem as quickly as possible. Thank you in advance to anyone willing to try and help me.
Find a kernel that's exFAT compatible our reformat to FAT32. The factory firmware s should be compatible iirc.
Tmobile is wrong about only accepting 32GB sd card.

I have tried both ways exFat and Fat32. I have over 32GB on the sd card, but once i put the sd in my phone the phone tells me the the sd is damaged. I am new to all this ROM, Kernel, etc... stuff. Where could I find a kernel that supports exFat or FAT32 and how would I install this on my phone without messing it up?
I think they all support FAT32, stock firmware should support exFAT. You might just have a bad card.

Have you tried a different 64gb card? I have no problem on stock rom using a 64gb card I got on amazon.
Like what he said. I've been on Stock for a month before switching to custom ROMs but within that month I've got no problems using my 64GB card. Try another card, might be your card is damaged in the first place...
I have tried 3 different cards. I get the same message with each card.
Did u try reformatting while the card is in the device? Or thru cwm?

I have tried reformatting while card was in the device. I am not sure how to go about formatting through cwm.
I also have a 64gb sd card. Works great.

I honestly think, if you've really tried 3 different sd cards, that you could have a bad MicroSD slot. You might go into T-Mobile and ask them if you can try your card in one of their S4's. If your card works fine in a different phone, then, if your phone is a recent purchase, exchange it, if it's relatively new, get a warranty replacement.
I formatted my 64gb card on my pc using an adapter & have had zero issues. Currently running Infamous v8.0.

Format to Fat32. I recommend creating a Live USB of Ubuntu and doing it through gparted.

Mine works fine
I have a sandisk ultra 64 in mine formatted out of the box for exfat and it works just fine. You should not be having those issues.

Could be a bummed sdcard. I had the same issue with a knockoff. Now I have a 64g exfat with no issues.

Always format any SD card in the device in which it will be used. This will always work and ensures that the SD card has the correct format for the device.

Works best for me when I have troubles with my SD card.
I always format from the pc in fat 32, the only problem is that you won't be able to write files bigger than 4GB into the sd
