I am stumped! I got a Sandisk 64gb sd card for this. Naturally, it came formatted as exfat. From stock through 3 different CM based ROMs, I can't get this S4 to read the SD card. I even downloaded a partition manager to format it to Fat32. I also wiped it and let the phone format it. Even after that it would read it. I know CM now supports exFat format. I even flashed separately the script from the original thread. In any case my laptop has no problem with the sd card. Any help appreciated.
I have a Patriot 32 gb class 10 that was working fine until s couple of days ago. Then the phone said sd card unexpectedly removed. Pulled battery and card nothing. Did a format still nothing put that card in my Asus transformer tablet. read just fine took the card thatvi had in my tablet without formatting it put it in my s4 and it read it. this is my 4th galaxy device they should have figured this out by now. Any suggestions.

The sudden unmounting and/or sd card not being recognized by the S4 and other devices as mentioned is a known issue that is usually SD card related. Sometimes it's just a matter of reformatting your card to Fat32 if your ROM cannot read exFAT cards.
But if that's not your issue or you already reformatted your card to the appropriate format, the SD card has failed and warranty/replacement is suggested.
Can happen to SanDisk cards in addition to other manufacturers.
You may hear this issue being associated to SanDisk cards if only because they are probably the most counterfeited card out in the market. But the issue can occur to non counterfeit cards also.
To reduce your chances of having theses issues happen, always get your cards from reputable sources, in blister original packaging, etc. And if the price looks too good to be true, it most likely is. Even if you take the above precautions, you can still have issues.
Always back up your data for that 'Just in case moment' in case stuff happens.
Purchasing a card whose Manufacturer and/or Seller has an excellent return/exchange policy is a plus.
Having a spare SD card available can help you troubleshoot what your issue may be regarding a defective card, formatting issue, device issue, etc.
You may want to take a look at this thread, as it may help you out:

I started to reply to you but my laptop crashed. Seems this s4 just doesn't like that 64gb sandisk. I had an 8gb card laying around and that worked like a charm. The sandisk was foramted exfat out of the box. I formated fat32 and didn't work. I wiped it and left it without format. Put in the phone to let it format the card. It did--fat32 and then still wouldn't read it or even mount it.
I sure don't have anything to lose by trying a different program to format that card. It could come in handy even if I don't use it in the phone. A camera comes to mind.
Oh yeah, it was easeUS that I used to format the card in the first place. Try something else.

Hmmm...
There have been issues with the 64gb SanDisk cards being read by the S4 as well as other devices as described in my previous post, the Ultra cards from what I've read (red & grey) I have the save card, class 10, running without issue on my previous S3 and current S4.
You may want to try the format link above.
You can always purchase another 64GB card on Amazon with a Seller with many, excellent reviews, and go from there, and return what you have to return
Right. That's the very card I have. Thanks for the help.

Anytime.
Let me know how it goes
This happen to me but with my galaxy s3...turned out sd card was corrupted. Good news was Patriot replaced it with a new one....
If the SD card didn't work in other devices I would seek to exchange it. There are other things I can use it in. I just ordered a 32 GB G skill on new egg. That should do it. The other thing I tried on this sandisk is partition it to 2 smaller ones less than 30 GB each formatted to fat32. Finally it recognized one of those partitions. When I get the other card I'll swap them.

I had the same problem as you OP. I've also downloaded programs to change the format type and stuff, but nothing worked, but I fixed it in a weird way.
My 64gb card didn't work on my samsung. I used many programs to format the card to get it to work, but nothing. What fixed it was....
I took that card and placed it inside my old smartphone (LG G2X). Once placed inside, a pop-up promoted me saying my card was damaged and it will try to fix it. I've tried this on my samsung and it didn't fix it, but once I tried it on this old smartphone, the card for fixed and started to work on my samsung.
I don't know if this could help you, but that's how I fixed my problem.
Format the card to Fat32.

I had tried that already when the device initially wouldn't read the sd card. When I partitioned the card in FAT32 then the device picked it up, but only one partition of 29GB.

I don't know what your problem is, then. My 64GB Sandisk card works perfectly in my Galaxy 4.
I don't know what me problem is either. When I have the time I going to return to stock and start over. TWRP won't backup onto the SD card either. Wondering if its behaving this way because I rooted the phone before putting SD card in. Though I have done complete wipe (including internal memory) prior to installing current ROM.

I have a SanDisk 64gb micro SD card in my S4, and had it ever since I got the phone about 1.5 years ago. now I am getting the issues you all are getting. I have NOT updated to a new firmware version. and I just backed up and reformatted the card. Very frustrating when all your apps disappear. come to find out they are all being stored on the SD card witch is now not responding... I will try a differect card. I wish they would just leave the phone a lot and stop doing so many updates.. they update one thing it screws up another. Ever since the first update my "Drive" app don't work, and they have no clue why.. not even Samsung knows...
oh well

Just curious as to how you got an S4, 1.5 years ago? :cyclops:
Odd SD Card Response
I have recently upgraded from a ATT Samsung Express (Tracfone) moving my 32GB SD Card into the brand new Galaxy S4 I Knoxed up right out of the box just as a matter of principle. I saferooted the phone and installed TWRP which for some reason refuses to load after a few succesful tries and a backup of my system and restore thern reload of TWRP. My concern in this question (unless some knight in shining armour can make sense of my TWRP issue) is that I am not able to write to the samsung branded SD card I removed from the old phone. I cannot create a ROM directory on it when the phone is connected to the PC, nor can I copy files to it. I had hoped to preserve the photos on the card and suppose I can break down and buy an adapter so it will connect to my PC but the point is it "should" work,, no? I cannot create a directory when the phone is connected to the PC nor can I in ES file Explorer. I've also tried to create a directory in root witth ES and am getting the same error. I just want to get the silly balloons off m screen and get google play to run. I am succesfully rooted. I've tried to reload TWRP with Odin only to get the small print int he uper right hand of the screen then no further. I am able to restore my backups thank God.
This is making me batty on a three step process. The card is my main concern right now as I can't load the ROM to it once I get TWRP figured out. Thanks in advance for all the great help I always get. The better I get the more I'll contribute....I promise.

I'm having the same problem. We are not alone, there are numerous threads in the other S4 forums, like this one http://forum.xda-developers.com/showthread.php?t=2281813&page=14
so another 64 gig sd card question, though im pretty sure mine is fresh. Got a 64 gig sd card class 10 (forget brand name, will look it up and update the post in a bit) i format it to exfat first, and pop it in my phone (using infamous latest, along with ktoonez kernel) phone immediately says sd card is damaged, try Reformatting it. i browse the sd card on my phone with rom toolbox. folders are corrupt (folders are named something along the lines of µideos~1 (my videos folder) or µusic~1 (my music folder), etc etc). i pop the card back in my computer, reformat, but trying fat32 this time. same result, pop in phone, says its damaged, corrupt folders. try formatting directly with the phone, pop it out to transfer my stuff onto it, pop it back in. same result, says damaged etc.
The thing is, the card works fine computer to computer. No corruption, but as soon as i pop it in the phone, above happens. Ive used the windows default formatting tool. Ive used easus partitioning and formatting tool and i have also used gparted (linux partitioning and formatting tool) all with same results. This doesnt just occur on my phone, this also happens on my friends verizon galaxy note 2 (running clean rom with sabertooth kernel).
So im wondering, is it a faulty card, a kernel problem, a general android problem, or am i doing something wrong with preparing the card with my phone?

Exfat makes my phone bootloop.
You never updated to say which brand of card it was. I still haven't had to buy a new 64gb card and am still using 32gb cards. I'd like to know which brands to avoid getting.
Well Samsung says it only officially supports up to 32 gbs, so putting in a 64gb is a gamble. I just ordered a 64 let's see what happens.

A 64gb card in exFAT format will work just fine on a GS4 out of the box. It's when a custom kernel that doesn't support exFAT get use is when it give troubles.
Oh okay cool good thing I'm stock

so as for branding, the friend i got this from is away for a while so lets assume its generic. theres no noticeable branding on the card so this is likely the case.
Though, i he did mention the brand to me when he gave it to me, i know it starts with an M.
anyone wanna suggest anymore tests i should run on it.

It might be a fake card I've seen em. I'm sure they have apps on the play store to check the actual capacity. That's probably the problem.

currently running a test on the card in the phone. its about half way done (currently, it wrote 35 gigs @9.5MB/s) so it seems though it may be generic, im one of the lucky few who have a working generic (except for the problem in the op, obviously)
so if this test does come back completely clean, what step should i take next. If tests on both the pc and phone are coming back clean, It should be something with the phone (more then likely the kernel) right?

Hi there
Almost a year to the day and im wandering if you ever figured out what the heck caused the: µEDGE, µIDEO, µOMICS, µUSIC and so on. Did you find a cure or fix? All i know is I have a Samsung galaxy S3 gt-19300 and a Samsung galaxy tab 2 7.0 I often swap the 32Gb sd between the 2 and all of a sudden this happens. I reformatted the card (which took soom doing) nothing happened there still there. any help would be appreciated.

You reformatted but nothing happened? Like, all the data is still there? Mine is doing that now; been using the same 64GB card for almost a year now and just recently it started showing as Generic Hierarchical instead of FAT32... I've used multiple programs in Windows and on the phone itself, and even GParted in Ubuntu; everything says it formats but after I unmount then remount I see that there has been no change... almost as if it's write-protected. I can read all my information, but unlike yours, mine isn't corrupted at all... but I cannot write or make any sort of changes to the contents.
Out of curiosity, if you do a chkdsk /f in Windows, does it mention anything about a dirty bit being set and unable to be removed? I only ask because mine does and no program or app I've used can fix it. Either way, I've tried everything but a low-level format (which I'm going to try in a few days) and haven't been able to find a fix. I'm thinking our cards might just be beyond repair...

My SanDisk 32GB microSD just got hit by this, too. Samsung Note3. Should I try data recovery on it?
Eric
I am having problems with my external SD card. It is a 32GB Sandisk card. I can create directories under /extSDCard and copy files to those directories. However if I reboot my phone all of the directories and files are gone. I went to setting/storage and select the external sdcard. The system tells me it is blank. I see in the notifications something about a blank sd card and something about unsupported files. I then tap that and it gives me the option to format it which I select. When I do that it immediately reboots and I am in the same boat as before I started. Basically I have an unusable SD Card. This card used to work but some time ago I accidentally formatted it in TWRP and sort quit using it for a while until today. Does anyone have any idea what is going on? I am running AOKP if it makes any difference.
Might have a bad SD card on your hands. But you didn't mention trying to format it on a PC instead of the phone. Then try transferring some stuff over to it again too see it it's ok. Just use the pc to drop a few files on it b4 placing it back in the phone...
If no quirky then possible dead sd. What size? Anything under 64 very inexpensive to replace on Amazon.com

Unfortunately I think the card is damaged. I formatted it on a PC and put it back in my phone and still see the same behavior. I then put it in another phone and although the format went as one would expect that phone reports the card as damaged.
Sandisk cards have issues with the Note 2. My Sandisk card went crazy after being in my Note 2. I just bought a Samsung card and haven't had issues at all.

Yes I just found out the card does work. It was actually a 64GB card. I put it in my tablet and it worked fine so I took the exact same model of Sandisk card that was in the tablet and put it in the Note 2 and I see the exact same behavior as the other card(blank sd and reboots if I try to format).
The card worked before I installed AOKP on the phone. I wonder if it is AOKP or the Note 2? This weekend I guess I will restore the backup I took before I installed AOKP to find out.

I took your advice and ordered a Samsung card. I really don't want to restore back to stock and get the KNOX update so I will stick with AOKP. I agree I don't think AOKP is the problem.
Been working fine for over a month now all of a sudden the SD card appears to be randomly mounting/unmounting itself and has become unreadable on my phone.
I've put the SD card in my PC and it works fine so I suspect my phone has developed a fault. I hope I don't have to get an exchange as it's otherwise faultless and I'm dreading getting a unit that can't be S-Off'd
I haven't modified or installed anything prior to the fault developing,
Any tips would be most welcome.

well, a simple solution is to enter recovery and see if the sdcard works there if this way it works, change the rom/perform factory reset, if this doesn't, well, you might try to flash everything again, but i's possible that the sd slot is broken...
i wish you all the luck, let me know
I would copy EVERYTHING off the card to a PC and do a format and try a different file system. I would has perform the format on the phone, to make sure its gets formatted to the correct file systems.
Long story short, It sounds like you memory card is starting to get Corrupted. I have to SanDisk cards that started doing that in the biginning and ended up not being read at all on PC nor the Phone.
Also while its doing that, youll also notice the battery start to drain more, at leasst thats what happended on my Note 3 when I had the san disk cards going corrupt.
Ended up buying new Card and now everything is fine.
I doubt is the card reader built in phone, more then likely its your memory card going corrupt.

I agree most likely the card. I'd download an sd card format tool and do a full format, don't use Windows format then do full check for bad sectors. I had a similar problem and it was the card at fault, but strangely worked ok on the pc.

I'll give that a go but why has it been working fine for over a month whilst exFAT if that is now the cause?

I have been through many a Samsung phones and always had corrupt sd cards in exfat. One day I saw a thread that said convert to fat32 and have never had a problem since.

Thanks for all the advice.
I could read the card in recovery but it failed to format there.
I tried to format in windows but my only options were NTFS or exFAT, no FAT32. But this failed anyway also.
Downloaded a SD format application but this said the card was write protected and to move the lock switch, obviously MicroSD has no switch like standard SD.
So next I deleted all the files on the card and ran h2testw test. This failed and reported card is probably faulty.
Then I checked the contents of the card again and all the original files were back again, so it's definitely 'Donald Ducked'. I was able to get all my files backed up and fortunately I had my photos already thanks to Dropbox & G+.
So I will now look at getting MyMemory to replace it but my fear is they will want me to return the faulty card but it has sensitive information on it that I can't delete. Any ideas on how I can wipe it?

How did you attach the card to the pc? Try a usb card reader and then try again. If still problems download mini partition tool (Google) and delete the partition. You can then wipe it properly.
I reformatted the SD card from the settings within the phone and since then it been working fine :\
make sure you're using 2.0USB also..
when i connect my phone to charger
Its been few days i am noticing when i conmect my phone to charger it says 'sd card removed unexpectedly or either it suddenly stops showing content from my phone, then i have to go to settings unmount/mount the sd card frkm storage option and then it shows the content even when charging, or sometjmes it doesn'fshow option for that so on that case i have to restart my phone. What could be the possible reason and solution to that. It was fine on 4.4.4 now i am on 5.0.2 all stock htc one m8 h/k edition with sim unlock and s-off via sunshine.
Known issue with 4.4.4 on Verizon Note 4? Any good work around? Even if I use a native app such as "my files" it doesn't delete files or folders. Pics taken with SD card location are lost with default camera. I can't seem to write anything to SD card. Even if I male the change on laptop removing the SD card from phone, as soon as I put it back in phone the directories are back. I've also tried non native apps. Nothing seems to work. My SD card appears useless at the moment. (64gb card)

Is it a Sandisk 64gb? If it is then I read a post in the S5 forum from a guy that is having a similar issue you are have, which I gather from your post, is that you can neither read nor write anything to your SD card. According the other guy he spoke to Sandisk and it's a bad batch of cards that radomly lock themselves and can't be unlocked.

I have the same problem with a Samsung Evo sd card. Transfer stuff onto it and it's gone when I look for later. They really killed android for me with this sd card lockdown. I liked my rooted note 3 without kitkat much better.

it is a sandisk 64 - the phone can read the data on it (pics, icons, apps (emulators/roms) but it will not write anything new to it
i have tried formatting it in every OS - the card is locked - i haven't taken the time to test an alternative card because most of my older ones 2gb, 8gb were also sandisk.

Not a card issue...Android 4.4.4 does not allow 3rd party apps to write to SD Card...
