Remove the card and plug it into the converter and plug that into your computer or card
reader then re-format using FAT32 ONLY then put it back in your phone and then your 64gb
sdcard shall work!

Use the Windows drive manager to delete the partition on the MicroSD, do not reformat it with windows, plug it into the phone, and attempt to mount, it should do so but with 0 space now. Format it with the phone. Or look for the tool "fat32format" on the internet (Google is your friend) in order to force a format in FAT32.

Then try exFAT but if you have a windows computer, the default is FAT32.
If that don't work you will need to find a friend or relative who has
a windows computer which you can use to format the card using FAT32.

thanks for the help guys, got it to work now. Can I install apps on the microsd?

nope, you cannot install apps on external sd on the s4 yet.
even the apps2sd is not compatible with the S4.

Anything but the applications installed themselves. You can store whatever you want on your SD, no limits, just no APPS2SD yet.

You can have all your mp3's, videos, movies, pictures and documents plus backups of the rom and new roms or other
stuff but you just cannot use it to install apps until one of the devs finds a way to create a compatible app which will allow
for app installation on external sd.
Something similar to the apps2sd app which is not compatible with the S4.
Perhaps the developer of that app will upgrade it making it compatible with our phones.

This isn't actually true after a certain version of windows i think since vista(May be wrong) exFat is the only option you get.

Google it and look it up,
Ever since windows xp fat32 was always the default when formatting usb flash drives(memory sticks) and sdcards.
Right now I am running windows 8 but I ran all the other prior versions of windows including windows xp.
When formatting hard drives, even external usb hard drives then windows (all versions) default to NTFS.
I never seen any versions of windows operating systems defaulting to exFAT.

Your right actually I got confused its actually partition space anything over 32Gb is out of a normal fat range for windows.

1) Make a LiveUSB stick of Ubuntu.
2) Boot into the USB stick.
3) Use GParted to format to Fat32.

Or you could search for 1 of the thousand formatting utilities that will do it and not have to download a 2gb file.

Do you know if due to the size of the memory card the phone takes a lot more time to load stuff??? I do not want to buy a 64gb if it will slow my phone a lot. If that's the case i may have to buy a 32gb card. Please tell me your input on this.

Well not in that sense but let's say if you would like to play a video or a song you have saved in your 64GB card. Does it still play it right away or have you experienced any slow downs? Someone who i know that works closely with phones informed me that it slows down the phone when loading files such as mp3 files or video files. Thanks dude.

Just format it to FAT32. You get better speeds that way anyways. My 64GB gets better benchmark scores with FAT32 versus exFAT

Aren't there other problems such as the 4GB file limit. I also thought there were other negative things with formatting an larger card to FAT32

[Q] Fail to download and or write to SD.

I have scandisk class 10 SD card 64 GB.
its formatted using the note 8 device (exFAT).
Whenever I try to download a file or copy a file in note 8 to the SD. It fails and reboots my device. knowing that reading from the SD is perfect. I can play music and movies from SD with no issues.
the only way I can transfer files to the SD if I connect the SD to the PC directly.
I am not sure if this is an issue with Note 8 or SD. please help!

Mine does the same thing. Ive tried formatting in exfat and fat32, didnt help. It writes fine to an old 16gb class 4 card ive got but not the 64gb. Sucks but at least it reads fine

I am not using any custom Roms. And i formatted my sandisk ultra 64gb more than three times but the same issue keeps happening. I also tried to find other apps to transfer movies and music files from Iinternal memory to sd but that didn't help. I can't even download directly to my sd. It reboots my note 8 if I try to download or transfer files to my sd.
Any suggestions?

I'm afraid nothing beyond painfully obvious ones - trying with another similar card, trying the card on any other device supporting exfat (if ok, this would provide definitive proof that card is ok), trying on freshly installed latest ROM, trying with the same card formatted in fat32.

It seems like this is the last resort. I will reformat my note 8 and try again. I also forgot to mention, that few weeks ago I was able to transfer one 800 mb file but this stopped happening. So it seems like there is not enough memory to transfer although I tried clearing the memory.
I will let you know if this reformatting the note 8 will fix the problem.

Reformatting the device didnt fix my issue. I am not sure now if it is the device or the SD. I need to test my sd in other devices and check if it will allow transferring of files

I am having the same issue as well. I try to move files from my internal too my external card and device reboots. I have the SanDisk 64GB card as well, it works fine in my S4. Could it be a software issue on the Samsung side?

[Q] CM 10.2 External SD card issue

I just installed the CM10.2 and am finding it difficult to work with the external sd card.
The sd card shows up on storage and I can mount and unmount it without issues.
The card will not be available unless an app is rooted.
I cannot use it with CoolReader which I used to do when I had the stock ROM.
CoolReader will only show the internal card.
File Manager will also show the internal one only unless root is enabled for it.
I did format the card through recovery as well.
Is it not possible to use the sd card without root privileges?
I had thought by installing a custom ROM I would gain more capability but I seem to have lost here.

Sounds like either an issue reading the card or a broken symlink. What kind of card is it? Try formatting it as fat32 on a computer.

It's a generic 16gb card class4.
I formatted it from recovery which I understand does fat32.
As soon as I revert back to stock i am able to use with all apps without a problem.

Try another Rom, one built from CM and see if it works. And be aware android devices tend to be really finicky when it comes to sd cards. Sometimes you have to format on the device, but sometimes it works better if you do so on a pc. I still say it's worth a try. Then if you still have the same problem, you might consider searching and asking in the Rom thread.

When formatting in Windows, it will ask you the cluster size. But now that I think of it, if the phone won't even try to format the card, it likely isn't detecting that there's something in the slot at all. If you bought it from a carrier, I'd bring it in and have them look at it with another card and give you a new phone if it's the slot.

I have the exact same problem. Using a SanDisk 32GB ultra microSD card. When I insert it, it says SD Card inserted. But when I go to storage, it does not pick it up. Mount SD card and Erase SD Card are both greyed out.

Maybe I'm wrong but need unlock rule for external sd card in androud system (Google add him in android 4.4).
There is a "fixsd" in the Google play market.

All is good now. Downloaded SD Formatter for Mac. Reformatted it, and it reads now.
