Hi XDA Family.
I recently flashed Omega Rom on my Galaxy S4 and everything went well. The next day I played my music from my SD card then there was an error "cant play this music file or something like this" after that my S4 was displaying that my SD card is blank or has unsupported files. The phone recommended that I need to format it using the phone. I formatted it like my phone said but it did nothing. Phone still displaying that SD card is blank or has unsupported files.
The next day bought a new SD card (8gb Scandisk) and the phone read it no problem. I transferred all my music to my new SD card and after playing my music the error appeared again and now both SD cards are showing that the SD cards are blank or has unsupported files.
Re flashed stock rom and stock kernel but still has the same errors on my SD card
Borrowed a memory card reader from a friend and formatted the SD card using my PC formatted it with all know file system. FAT32, exfat and NTFS but everything is not working.
Lastly I tried my SD cards with another Galaxy s4 and they worked without problems, formatted it using the phones formatting capability inserted it on my S4 but still has the same errors.
Any suggestions are greatly appreciated guys.
Thanks in advance.
Any help would be greatly appriciated.
I have The same problem.
Pls help

Hi! Thanks for replying, I was beginning to lose hope that anybody would reply. Tried your suggestion. Downloaded 3 scanning SD card apps on Playstore but none of them worked. Both of my SD card still shows up as blank in my S4.
This only happened after i flashed a ROM, anything I still need to do to go back to stock? Already flashed an official softwas and kernel.

Hi Good Morning!
Tried that last night still the same problem. Tried the chkdsk on CMD still the same problem. I can buy another SD card but I am just afraid that maybe a week or two the sd card will mulfunction again and I cant forget the fact that my PC and other S4 can read my SD cards.
Two possible reasons. Sandisk SD cards supposedly fail easily but yours is 8gb so it should be ok.
Next reason is Omega Rom bug, I personally don't have this issue but I have a similar one. My Sdcard does not mount as r/w automatically.

Thanks for the reply lamstone, I have read somewhere that disabling the automount helps. Can you help me on how to disable automount? and can I do it if I am on stock firmware?
Thanks
Just use the card reader and adapter and attach it to your computer and format the card using exFAT file system. Then use it in phone. AFAIK the current custom recoveries already support exFAT. So you should be fine for anything. I had similar issue with my 32GB Sandisk Ultra card when I formated it using phone. No issues since I formated it as exFAT on PC.

Hi thanks for the reply.
Tried Fat32, Exfat and ntfs and all of the still has the same error. Actually bought a new 16gb sd card earlier I popped it in my s4 and still has the same problem.
This started happening when I flashed Omega rom. Is there anyhow I can check if I have a stock everything? My kernel, recovery and firmware?
thanks for the patience.
BUMP!!!
Anybody who can help me??
Another update is that I installed CWM recovery Philz Edition and tried hooking it up on the UBS cable and mount usb storage. My computer can now see my sd card inserted on my phone. Tried reformat while my phone is on CWM and connected thru USB cable and formatting goes thru but phone still says SD Card is blank or has unsupported files.
One thing that is strange though is that when I try to copy things to my SD card while my phone is attached to the USB cable my PC freezes like it cant copy any files to my SD card.
Any help would be greatly appreciated.

I have the same problem. I bought an 16GB class 10 Kingston SD Card and inserted in my phone . Nothing. THen I disabled Developer options and it appeared. Then I though I will reformat it using directly the phone. Ok. Tried to use it bam "unexpectedly removed " and nothing. Then I tried another SD Card and the same happend first good then removed and so the third one.
Any updates on this thread ? Did you manage to make it work ?
This phone is pissing me off. I am having same problems with stock music player and Goohle Play Music app giving errors on any tracks in my Sandisc 32 gb class 6 micro SD. I have started to wonder if it is related to me using the Samsung Smart dock with a 500 gb external HDD to watch movies on HDTV. It mounts the drive and works great but following day I was try to play music that worked day before and now I get unsupported file type error and other error.
I tried avg to check for a virus(which is unlikely imo) and it shows no virus. I just tried this SD on another android device (Nabi 2 tablet running 4.0.4 and all songs play PERFECT without error. This must be my At&t galaxy S4. Any ideas anyone? I really dont feel like reformatting the sd since it seems to work fine on tablet. Also: I already wiped both music player apps in settings and eventually uninstalled and reinstalled the apps (and another musiv player also) to see if it was cache related. This made no difference.
Edit* oops. After rereading OP... I think I posted this in wrong thread.lol. But my issue with S4 and SD card error with music playback is similar so Ill leave my post unless mod wants to remove it. FYI I fixed my issue(somewhat). Ths SD card is fine as I suspected. The phone has an issue having stock music app, play music and mx player. Either one of the apps was running in background or the system was running sound in background. Hope to not have problem repeat itself. I bet custom rom would fix this if AT&T hadnt locked phone with sneaky update.
You can try flash Rom Cook MH8.
I think your problem will resolve.
Thanks
i think you need to try this.. Get your SD card and try to put in another phone example Blackberry (im not sure if it will work on HTC, alcatel etc. except samsung).
then format using other phone. after formatting ffrom other phone. reinsert the sd card on your samsung unit. then check the storage and try reformatting again using your Samsung.
still nothing
Well. I still do not know how to fix this and I searched and tried almost everything. Only thing that I think might be wrong that somehow the "auto mount SD " does not work.
Because the card is there. The phone cannot see it . Other phones do fine. And in CWM even I can see that there is indeed an SD card but cannot acces the files.
So... I really do not know
i am also having this problem but nothing seems to help have tried alot of thing but yeah :/ sp i have given up on it ! it is a 32 gb sd card loved it.. now i almost got anxiety cus i have so little storage xD hehe well well might buy a new sd soon
My class 4 32gb sdcard too stoped working properly these days.Sometimes it gets unmounted randomly or it doesn't get detected or it shows blank sdcard.I don't know what cause that but the best I could have done is to backup my data and buy a sammy 32gb class10 micro sd.I heard that S4 has problems with sandisk ones.

UPDATE:
My SD Card problems has not been fixed until now!
I just flashed the leaked 4.3 firmware and I tried to insert an SD Card just to try it and BAM! it worked!!! I am now afraid of rooting my phone because maybe the SD Card will not be working again but as long as my SD Card is working I am good!
Anybody who has problems with their SD Card should try to flash this:

Hi All,
I have a stock non rooted Note 3... Recently bought a 32GB class 10 micro sd for it... Whenever I change the storage for camera to sd card it clicks a picture with an error of unable to save to sd card switching back to device storage....
1) Why isnt it able to use the sd card for storage
2) I have formatted the card multiple time both via pc n phone
3) read abt read-permissions but didnt find much applicable info
What can i do about it as I can copy paste file via pc to micro sd successfully and the files reflect properly in the phone...

Try using a different microSD card? My class 6 32GB works!
so does this mean that the card is corrupted i will test another card and confirm...
Likely the card is the issue.

I have conducted these tests:
1) Used my 32 gb card on my old note 2 and camera is able to save pictures directly on it
2) Used my old 16 gb card on my new note 3 and camera is able to save pictures directly on it
Conclusion:
1) Note 3 is functioning properly with 16gb card but not the 32gb card
2) My 32gb card is fine as note 2 is able to write on it with no issues
There is a problem with Note 3 unable to write on a working 32 gb samsung class 10 micro sd...
Awaiting a solution..
Is your card anyway protected or something? I got 32gb class 10 card from Samsung and and it's working fine (If I remember right the card was some red/grey colour, bought it couple months ago and it worked as well in my old S2)

I have finally tried additional steps with no success:
1) bought a new samsung class 10 micro sd card --- not working in my phone
2) formatted the new card --- no change
3) used it in my friends note 3 and it worked fine
4) did a factory reset on my phone --- it worked for 2 mins and again started giving the error
what is the issue here???????
For what it's worth... Although I have a Note 2, after updating stock Android from 4.1.2 to 4.3, I recieved the same errror. You might also have 4.3, since 4.1.2 has not been delivered on the Note 3. Maybe an Android 4.3 issue, instead of a Note issue?
Solved. I checked my SD card: 2 corrupt files. After making a backup of the SD card, I performed a full format and placed all files back on the SD card. Camera now stores pics on SD card. Card clearly had an issue. Whether this has to do with android 4.3 or not, I don't know.

I just talked with Samsung support after a 64gb class 10 failed and a 32gb class 10....They told me that their phones dont support class 10 cards officially and that they are known to fail. They suggested that I ask the card manufacturer to replace the card with a lower class.....something about the way files get written...basically they know its an issue but dont have a time table for it to be resolved if it will be at all.
Can't write to Note 3 SD card
I have the same problem, I can only write to the SD card if I take it out of the phone and do it with my computer.
I purchased a Transcend 64GB card with the phone. The dealer exchanged the card after he satisified himself there was a problem.
I still have the same problem.
Can't write to the card, via any of the following (or get a partial write and failure with a corrupt file) USB, Kies, Airdroid, or file copy from internal to external card.
I have to take the card out of the phone and write to it with a PC, then I can read the files.
I'm beginning to think this is a manufacturers defect in the phone, I've seen a couple of other posts on this same subject. One was on the Sammy site.
I would like to solve this issue without having to submit my phone to Sammy under warranty and be without a phone for however long.

The only way i could fix it was to use a Samsung 64 GB Class 10 card... but that card as well is a little dicey to use as once my battery went low and the phone got switched off and corrupted the memory card... so i just use it for movie storage, no camera pics...

New Card only works a short while.... Then
When I had my Transcend 64GB card replaced, it was ok for a short time then it went back to the old problems. I can't write data to the card while it's in the phone only when written from a PC. If I save a file somehow from the phone (which usually fails) the file will be corrupted, such as a song or movie it will not play smoothly, or perhaps at all. Save it from the PC and it's ok.

Actually android 4.4.2 kitkat can't save anything to sdcard...except samsung's app, because i had this issue too
Can't write to SD Card on Note 3
I was having problems on JellyBean 4.3 with writing to SD card, got a new card and everything seemed ok for a little bit. Then issue returned. Upgraded to KitKat 4.4.2 and problem is worse if anything.
I have seen fixes for this issue if you are willing to root the phone and void warranty to fix it. I have 3 other rooted devices, I could root the Note 3 but it's brand new, I don't want to blow the warranty away.

hello...here's my problem:
I just purchased a 64gb sandisk sd card and it doesn't not work...
more specifically:
1) whenever i re-insert the sd card, it shows "blank sd card, need format" (ONLY if i formatted the sd using my pc before i insert it back)
2) i tried to format to exFat and FAT32 through my pc, it works..but when i insert it back, it's gonna show either "blank" or not able to read any files that i copied to it.
3) when i connect it (inserted to the phone), i cant move a large number of files, it's either gonna disconnect or some errors.
4) i notice whenever i managed to copy all my files to sd, after reboot, it's gonna show "blank sd" again.
5) i also try copying the files to the phone first and then move them later using phone's application, but when i wanna use those files, it's not usable.
6) i think sometimes it deletes all the files that i moved from phone to sd card.
Please help! any suggestion will do...ihv been looking for answers in this forum for like 3 hours.
(English is not my first language so bear with me)
do not use sandisk 64g, mine got file not found at random, using 32g is fine
As mentioned sandisk has gone downhill...Ive had issues with them also. That said it sounds like your card is no good. Return It if you can
Sent from my SM-N900W8 using xda premium
If you can return it--recommend the Samsung 64gb Class 10 on Amazon
ZERO issues and pretty fast
Did you try to format it with your phone ? not PC.
Because i also have Sandisk 64GB micro sdcard i had it since Galaxy S3 and now use it with Galaxy S4 , and have zero problem with it , it works just fine. I keep it almoust always full and even encrypted it.
Hello,
My GS4 (1337) isn't detecting my microSD card. My computer reads it and I've reformatted using SDFormatter, as recommended by many users in this forum (FAT32).
It's not detected in CWM 6.0.4.8 and PhilZ Touch 6.43.8, either... I've tried multiple ROMs and nothing seems to work. I've tried two different SD cards, as well. Each ROM just says to "insert SD card"
Are there any settings in ServiceMenu options that might be affecting it?
I've gotten 2 replacement SD Card/SIM card readers off of eBay and neither of those replacements have done the trick. Thinking there's something software related.
Thanks in advance for help.

Hi,
When I had an issue with a sdcard I plugged it into a camera and formatted from there. Maybe you have a friend who can lend a cellphone to you for this? Sorry, for now I'm out of ideas, only these two. If I come up with other idea I may post here again.
~Lord
if you insert it while the phone is ON, does it not even recognize that a card has been inserted? I thought that normally it will at least tell you that the inserted card is not readable and ask you if you want to format it?
is the card fully working on your pc? like, can you fill it with files to it's complete capacity without corruption and they are all read by the pc? if not then maybe a duff card? this is often the case if you buy cheap card online.
have you got a smaller capacity sd card that you can try in the phone just to rule out hardware issues on the phone itself?
Please cleans your micro sd hole with a spirit(which use in clean u r desplay)...nd format yor sd card in default extension. ..I think it worked...

I have also formatted the card (FAT32), done chkdsk on Laptop and even reflashed ROM, however card is not mounting and the error that it is either Blank or unsupported file system keeps coming........
Also, i have been using the card on kitkat custom ROM for last 7-8 months without ne issue and now all of sudden its nt getting detected.....
Ne solutions/suggestions to fix this..... May be some file gone corrupted and any module/file to fix this ???
I really dnt want to go through Samsung service centre route for this

The problem has been exist since note 2 that: Samsung phone generally doesn't like Sandisk Cards.
Friend of mine had a 32Gb SanDisk microSD on his Note 2. From time to time, the phone acts as the card ejected for no reason. After a few months of battle, it just couldn't be detected it any-more.
Solution? Get a Samsung SDCard instead.
I bought him an original Samsung SD card while I was in Hong Kong at April. 4 months have passed, so far, no problem.
His Sandisk has been sat in my mum's N7000 (Note 1) and worked like a charm. :fingers-crossed:

Unfortunately, it could also mean that the midcroSD port is toast. I would look at that first -- see if there's any dust or foreign material in there and gently clean it out if you find anything. Then borrow a friend's microSD and see if it works in your device.

Done that and its not mounting any card. In fact all cards are giving an error "Blank SD card or unsupported file system" and these cards are mounting and reading well on my wife's android.
Guess problem is software related, as card is getting detected but not reading/mounting properly. Any leads to any modules/files for solving ths ???

As you have said, it is software related, so you have some options:
- Reflash the rom, or factory reset
- Report the problem to the rom's creator for fixing
- Or try another rom/firmware.
Change the rom
Not the rom or any sd card. Has to do with Samsung not supporting up to date 3rd party app permissions. You need to root your phone, then use fixsd app. I'm in the exact same boat on galaxy note 3 w/stock rom 4.4.4 kitkat and kernel date of Aug 28th 2014. Once again, an attempts at copying, moving, writing to sd card, you will have the error.
Same Here - Any fix?
I just got a used Note 3 (N900 international) off EBay. I am having the exact same problem here. I have tried lots of different brands/sizes of microSD cards and none can be mounted. It is possible that the card slot is hosed. This is on Lollipop. Without this, the phone is not very useful to me. So any fixes? Thanks
BTW - all of the cards are formatted fat32 and work fine in Windows. I have tried allowing the phone to format the card when prompted. Seems that the format attempt fails too.
I just got a used note 3 and my SD card is doing the same thing except I don't get an error message it just says in my storage that there isn't an SD card and o have also tried 3 other ones all different size and brand. All of which have been in a few different phones and worked just fine. The one that's current in my SD card slot I had in a note 2 until I got this note 3 and it worked perfect. I looked it up and found that the note 3 not reading any SD card is a hardware issue and the only way to fix it is repair the SD card slot or replace the phone
Looks like I have the same issue than most of you guys !
I'm running Cyanogenmod 12.1 on my SM-900W8. I tryed original samsung OS , factory reset didn't change a thing.
I tryed 3 microSD, a samsung evo 64GB , a sandisk extreme 32GB and a verbatim 8GB.
All of them work very well il my laptop but since a week or two , my note 3 refuse to detect any of them. It was working for over a year , then some random message started to show up ( something like unexpected sd card removal ) and I completely lost it right after.
They are not detected in TWRP either.
I'm looking everywhere on the internet but I don't find any fix for this particular issue. The only thing I saw is some brand new simcard / sd tray that need to be soldered. If that's the way to go I'll find somebody who can do that but I need to know first !
