SD Card Randomly umounting itself

Hello All,
I replaced the SD card in my DI (Stock 2.1-update1), with an older 8GB I had laying around. Now every once in a while the phone says the card was removed without warning. Powercycling the phone won't bring it back, however a battery pull will, as will ejecting and re-inserting with the phone on.
This leads me to believe it's not a contact issue (as the battery pull fixes it)
I want to see if anyone else has similar problems, and try and see if it's just a ****ty SD card (I don't have another to try long term, but I can just grab a 8/16GB from amazon if I have to) or if it's related to bad hardware in my phone, or some software issue.
Thanks in advance,
Spencer

I haven't noticed random unmounting of the SD card, however I've noticed that when I plug my phone into a usb port of a Windows 7 machine it will mount the SD card.
Some apps will notify me that my SD card is mounted and I have to manually set my phones usb mode to disk drive and back to charge only in order to unmount the SD card.
This happens on the leaked 2.2 with the 2gb SD card that came with my phone.
Maybe both instances are bugs?

Is your SD card formatted to fat32?

My card is formatted in FAT32, with the 2.2 leak, and it unmounts the SD card whenever I plug it into the stock charger in the wall. Would reformatting it to something else stop that?

My card is formatted with whatever the phone formats cards as. Mine seems to stick to USB only when it's plugged in, maybe just a bug of the leak for it defaulting to something else.
Do you have Sync installed?

In my experience, I was running the 2.2 leak with hydra kernel and it was giving me an SD mounting error constantly. Never did I have a problem with stock. Thats why I just went back to it actually.

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...

Have you tried reformatting the SDcard through either Settings > Storage or on a PC? Make sure you select FAT32 or exFAT if you use a PC.

If the card (formatted as FAT32) is not visible on PC then the card is broken.
If the card is OK on PC but you have problems in the phone you need to test with another (good) card - if that is also not detected you have a problem with the phone (since you said the problem was also 100% stock ROM then it is not software, possibly some pins in the connector).

I have tried this card on pc . It works fine . I have tried another card on my phone and its not getting detected (same issue) also the same card works on pc too. Samsung service center said its not hardware issue but a software. and just because my phone is not bought from my country they refused to touch it without a condition that there is a possibility that phone might get bricked if they touch software and its fully my responsibility if it happens so.

Yes it works on another phone. Files are being read too.

I am facing the same problem on my N9005, inserted the sd card from my S4 in the N9005 and it shows up as blank, put it back in the S4 and it's working fine,
Tried a blank sd card and it shows up as blank and unsupported. When formatted the SD card still doesn't work, help :S

After a month of researching and **** i finally gave up and started living only on my internal storage. I have sacrificed my 15GB Media because of it. F*** this **** . I think even you should give up. :crying:

well I am going to try to update it, doesn't seem like it could be a hardware fault, haven't seen such a hardware fault ever. hopefully it will work. if it doesn't then will have to try something else

Well, update to XXUGNJ2, didn't help at all
What to do?

I've tried all apps related to SD Card mounting . Nothing Helps. Though if you provide me the link ill try it once. I cannot find the exact one you are talking about.

Hi there. I have a 9005 and no luck on making sd to work, already gave up, just living on 32 gb internal...

Iv had something like this happen once. use software to unpartition the whole thing and then reformat it to fat32 or exFAT. there might be a problem with it not being a logical drive. does computer management pick it up when u plug it into the computer?
