[Q] Can not mount SD card

Hello!
I really need help.
I have stock EG22 rom and 32gb SD card. Everything was ok but suddenly I can't mount SD card. If I'm loading into Nandroid everything from SD card available. But if I'm booting the system nothing available and "MyFiles" app says your SD card not inserted.
Few times tried to change the Rom and cleaned data. Nothing helps.
Phone is rooted
Please, I need help, advice, etc? Help me, please?

Suggestions
For me, anytime I have an issue with my SD card, I take it out and clean the connections. Retry.
If still no dice, I backup everything to my PC and format the card. Then I move back critical folders/files, insert the card and try again. (This usually is the fix.)
If still no luck, then if you still have the SD card that came with the phone, try that one.
Could always try reflashing the rom again without wiping data.
Did you have this problem on Froyo?

Didn't have this problem on Froyo and I think I'll try to odin EC05 rom.
Thanks

I have the same problem on the SUPERNOVA ROM,Weird! My friends don't have this problem on their epics with supernova. is it a bad download??

It could be a sign that the SD card needs reformatting. This has fixed issues for many. Doesn't hurt to try. Backup all data on sd card to a computer then reformat sd card in the phone...this is important for best compatibility. Then restore your data.

Most likely a rom issue but I do have to say that the EPIC 4G can and will kill and SD card. They have problems getting hot, especially if you use the LED flashlight app and leave it on for awhile, the metal harness around the microSD gets really hot and bricks the sd card. My epic 4g ruined my 8GB card as well as another 4GB card due to this. My 4GB card will not mount, will not format, not even in a computer so It is toast I assume and my 8GB card just doesnt get found.

It also seems to be very finicky with the 32 MB cards. So def reformat. Also Gingerbread leaks seem to access it slightly differently than Froyo ROMs. So problems show up in GB that don't in froyo.

You were right. I've reformatted the card and right now it is working. Actually, it didn't matter it was a Froyo Or Gingerbread.
After reformatting everything works just fine.
And I did reformatted it on my computer, because my phone was not doing it.
Thank you very much!

SD card becomes Read-Only after a while

After using my phone for sometime, the SD card becomes read only.. I can't modify anything on the card. Apps like Zedge don't start because it says SD not detected. The camera clicks pictures but nothing gets saved. However i can watch videos and play songs but cant write anything on the card. Remounting the SD solves the problem temporarily.
Running stock GB rom, rooted. Does anyone else have this problem? How do i fix it?

Boot the phone w/o SD once and see if help if not u might need to reformat ur sd

I faced a similar problem with my defy
Try to install MiniTool Partition Wizard Home Edition (google it, its free)
use external card reader to mount sd card and select the memory card
select wipe the select the last choice (phases) the select apply, it will take more than 8 hours to finish
then insert to your mobile
also it is better to install CM7.1
I made that it and it worked for me

In custom ROMS this has never happened to me.. when i reverted back to stock i found this issue
8 hours? really?

Me too facing the same problem!!!

Use external card reader and use HDD low level format tool.

Did you happen to not safely remove the sd card from USB storage? Also have you tried using a sd card formatter there are plenty free to download and may fix sd cards not recognized by windows. I have had this happen but only when I flashed wp7 and messed up my sd

My S4 (GT-19505) cannot read SD cards (SD card blank)

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:

[Q] GS4: SD Card not detected; used SDFormatter

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...
