FAT32 is the recommended file system for SD and SDHC cards ... a 32gb SD card is an SDHC card.
exFAT is primarily for SDXC cards ... (i.e., greater than 32 GB).
Both FAT32 and exFAT are Microsoft designs.
I suspect your issue is directly related to LINUX and the inherent formatting of your internal storage where I presume you are downloading your videos/images to before moving them to your SD card.
If your videos/images individually are not exceeding 4 GB there is no need to go to exFAT on an SDHC card but because the LG G4 supports cards greater than 32gb, i.e., supports exFAT, you will be able to see them when moved to your card.

Yes i know. thats why i formatted to exFat, sometimes i need 4gb+ files.
I just directly download to SD card with phone.
Im thinking its about LG's software. deleting files is so slow (2gb files 10sec+) and not refreshing in gallery.
I was readed somewhere fat32 have (log daily feature) or something like that for changed files and accuracy files idk properly but exFat not have this maybe its about that.

Before coming to that conclusion ...

Before coming to that conclusion ... i.e., thinking it's about LG's software, you would have to test out an SDXC card and see if you're having the same issue. Then you might be able to make a case to LG if everything else is set-up properly.
When you state you are downloading to your SD card directly with your phone, how exactly did you set it up ... ?

Oh. You right i thought SDHC can handle exFat but have problem with compatibility. But you can use anyway if you need.

You're not using adoptable storage ... for the set-up of your sd card are you with android 6.0, Marshmallow? Needs to be set to portable I believe ... irrespective of what you've set in Opera.

Then borrow or purchase an ... SDXC card and see if the issue recurs when formatted as exFAT.
You could try re-formatting your card with a different program and see if it helps but It may be your phone is having trouble reconciling a 32gb card to exFAT.

SDHC driver in Crossbow?

I'm curious if Crossbow has a new SDHC driver? The previous SD driver was based on v1.1.
Has anyone tried a SDHC card with Crossbow to see if it works?
Universal doesn't have SDHC hardware, so driver software should not help.

I thought that SDHC cards were the same hardware as regular SD cards, just formatted to FAT32. Is that not the case? I thought by virtue of the fact that many of us are happily using 4Gb SD cards (formatted with FAT32), that SDHC cards would work fine?
Devices that wouldn't handle FAT32, and therefore restricted to a 2Gb maximum are officially "SD", and those that can handle FAT32 will be labelled up "SDHC" to avoid confusion by non-techies.
My mate has a Casio camera that would always shut down as soon as you put a 4Gb SD card in it - he formatted it using FAT16 to 2Gb, and it recognised the card, but couldn't use it. He formatted the card with the camera, and it worked fine, but only with a capacity of 1Gb. I use this as an example of what I expect SD/SDHC compatibility to be like - simply an indication of the file system, and capacity limits that a device can handle.
Cheers,
Steve.

i agree with you... but i tried a card... it refuses to work with exec
kingdomraj,
Which ROM version do you have? Is your ROM Crossbow?
Difference between SDHC and SD its the same as between CD and DVD - U can use SD in SDHC HW but not SDHC in SD HW. Not all can be changed via drivers!

My arc cannot recognize formatted SD cards, help?

I've tested two sandisk class 4 SD cards.
If I format it to fat32 and partition the space(to use link2SD), my phone refuses to use the SD card and says it's not there. I use minitools for partition and the official SD card maker software for formating. I did everything by the book and tried multiple options(different labels, ntfs, ext2, etc.)
A fresh, unallocated space card works perfectly fine however.
My phone is rooted and unlocked bootloader running softMIUI rom with a modfied power saving blend kernel.
Please help! This is confusing the hell out of me.
Was looking at your post and I decided to grab a few of my MicroSD card 1gb, 2gb, 4gb, 8gb and 16gb....
I formated all of them on windows .... right click format, all default settings... Fat32. These are MicroSD cards that have had information on them... they all run fin on my arc. All different brands.
This leads me to believe that there's possibly either something wrong with the MsD card or the reader on the phone.

Solved it
Did this:
Changed the partition id to this:
"0*06 fat16,greater than 32 mb"
and made the second partition fat32 as well.
Removed the 100mb linux swap file partition I created....not sure if that was necessary.

[Q] 64GB SD card unformattable in AOSP & AOKP

I have had my GS3 for a little over a month, rooted and had no issues, I installed another rom with no issue. Unfortunately when I tried to install a CM10 or AOKP rom, each say my ext sd card is damaged and needs to be formatted. I try to format, but it hangs and then just quits without completing the task.
I have tried formatting to fat32 on my PC, downloaded EaseUS Disk utility to format, but none seem to work. When I restore back into the previous rom, it still says damaged and then I can format and start over only in that non AOSP/AOKP rom.
I boot into recovery when the AOSP/AOKP roms are loaded and it wont even mount or format in recovery either.
Any ideas?

I think I read somewhere that in CM10/AOKP that it won't read/understand exFat very well.
So, formatting to Fat32 is definitely the way to go.
When I used some other programs it would say the same thing... that my card was damaged and had to be fixed.
I had a heck of a time finding a program that would do it for me on my 64gb sdxc SanDisk card!
But I found a free one called GUI Fat 32 Format that actually worked.
Click this link and it will start to download:
http://www.ridgecrop.demon.co.uk/guiformat.exe
It didn't work immediately, for me at first, but after a few tries it actually worked very well.
I think that once you get it into Fat32 all of your problems will go away. Hope so anyway.:cyclops:
Let us know if it works!
This seems to have corrected the issue, finally

Glad it worked for you!
Sent from my SPH-L710 using xda app-developers app
I had a similar issue... I flashed an AOSP ROM on my phone n it corrupted my sd card and wouldn't format. before formatting I went back to a touchwiz ROM and it still said it was a bad sd card and needed to format I ended up formatting my card in my phone and lost all my data. I put music on my sd card and removed the sd card from my phone before flashing another AOSP ROM. After I installed another AOSP ROM I re-inserted the sd card and it again said it was bad and needed to be reformatted...
So my question is...How can you use a 64gb sd card on an AOSP ROM...I'm back on touchwiz for now. Sd card works fine.
Does formatting the sd card in your phone format it to exfat and not fat32?

Wait, so you're saying that AOKP/CM10 don't have the necessary drivers to handle exFAT formatted sd cards?
Do you remember where/how you came upon this information? Was this issue particular to 64gb SDXC cards vs smaller SDHC cards or maybe to certain classes of cards?
I find this shocking, but I can't say it isn't unfounded.
I have a 64gb uhs-1 sandisk card coming from newegg in a few days, so I'm obviously concerned.
Any insight you could provide is greatly appreciated!
Hey guys... after doing some fooling around I've found out some (useful) information for people with 64 gb sd cards...
1. When you format an sd card while its inside your phone it will format it to exFat.... which is fine if you plan on only staying on TW ROMs. This format is not compatible with TWRP Recovery and has given me issues (causing me to loose all my data on my card) just by flashing an AOSP ROM
2. If you use the program posted in the second post(thanks iomega311) you can format your sd card to Fat32 and it will now work on TW ROMs, TWRP, and AOSP ROMs.
Hope this helps for anyone with SD Card Questions/issues.
In my opinion... Never program sd cards on phone... Always use a computer. Especially if you want it done right!!!!

CM 10 which all the AOSP roms are based off does not support exFAT since it is a proprietary format and they don't want any legal trouble. The best way to format a 64GB gard is with GUI formatter
What allocation size did you guys use? Just got my 64GB SDXC and need to format it so that I can use it on CM10.

how do i know which sd card do i have?

i want to use this app:http://forum.xda-developers.com/showthread.php?t=1889550 but i see it dosent work on exfat and i dont know how to know if i have exfat or fat32 please help ..
I'm using directory bind (latest version) on exfat and it works fine for me. You can just put the card in your computer and go to its propertes, it will tell you which format it is on.
64GB micro sd cards usually come with exfat format out of the box. 32GB usually FAT32
i think most sdcards are fat32 by default--may be wrong--but you can research phone specs or Google sdcard specs for n2.
Not aware any card comes with exfat--if you are original owner it should be fat32
you can also use partition programs like gparted or sdformatter that should list the sdcard and say how it is formatted--
either way backup sdcard first and even phone

SD-card filesystem

What filesystem do you use on G4 SD-card?
Why? What version of OS you have?
exFAT for external micro-SD card in LG G4 H818P. R/w perfectly. BB used Win7 x64

Do u do anything special to get exfat working? Do other apps see the exfat sdcard as an available source to access? I tried exfat but kept getting the error saying unsupported file system. Thanks
@welder73, not sure which is faster but exfat support larger than 4gb files while fat32 doesn't
About speed. I did'n see difference between exFAT and FAT32. About the same.
And I did'n do anything special to get exFAT. Just formatted micro-SD on PC via SDFormatter utility. I thing exFAT support may be available or not on different ROMs for different countries. I am on stock v10d-CIS. It's ok by default.
Also I saw then users flashed rooted system from one region to another stock ROM (SEA, PHL) - no exFAT support. May be answer is in some files in system (bin, etc) or in some files in another images from full KDZ/TOT.

ExFAT on a big SD card. Because it's a one way street on a phone capable of shooting videos that cost half a gigabyte per minute.
Stock marshmallow H815 EU.
Didn't have to do anything special other than format it using the native windows 10 format application. Phone accepted it no questions asked.
Speed wise don't expect observable differences over previous file systems. SD card hardware is the main factor.
You have to use Fat32 for SD cards smaller than 32 GB and exFat for SD cards bigger than 32 GB. Speed and reliability depends on the brand of the SD card. I used without issues a Samsung micro SDHC EVO UHS-1 (32 GB) and a SanDisk Ultra Android microSDXC, 64GB, 80MB/s, Class 10, UHS-I.
