[Q] Frustrating SD Card issue - not the normal - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Note - this is not the "Damaged SD card Issue" i never received ths warning.
Up until last night, my New S4 was running great with my Samsung 64gb sd card...had a ton of programs etc. The thing is, the card was also encrypted by company security policy. Prior to flashing to a new rom i tried to decrypt the card, the the system credientials were locked and wouldn't let me (after removing accounts etc). I don't want to talk about ways i could have decrypted - let's just say i went into the flash with an encrypted card.
Wiped cache, delvik cache, and factory reset
now i don't believe this cleans the internal (SD or storage) as this is where i flashed from
Everything flashed successfully and the new rom is up and running.
Except now i can't access my SD card on my Galaxy. Mounting only results in the device saying "it's safe for removal". I can't even format on this device, but i can on a galaxy s3 and my laptop. And the card works in all those places just fine. The card won't even mount in CWM....EVERY time I insert the card, I'm just told the card being checked for errors and immediately goes to "card is safe for removal"
anyone know what might be going on? This is driving me nuts here!

Just tried reflashing again, this time clearing internal memory too...installing rom from a diffetent external SD card and still no luck. Same result as above.
Again SD card works in all other devices other than s4.
Also note I am using a T MO rom on att device with new kernal. I don't think that should matter though

Had this issue. I used my 64gb card with the stock rom. I flashed CM10.1 this morning onto it and CM10.1 wouldn't read it. Took it out, put it in a SD card adapter and read it on my laptop, copied all contents off. Put it back in my S4, formatted it. It worked. Put card back in laptop, copied content over, worked fine on the S4.
It's a formatting issue. Just back up your data via another device, then format the card in your S4 and youll be fine.

Problem is I can't get s4 to the point where it will format the card. After I attempt to mount it...keeps reverting back to ready to remove message...as if it doesn't want to know the card is there.

Well. Try formatting it in another system. Take it out copy your files off, then format it. (Windows My Computer, right click the flash card, Format). Mac, Applications>Utilities>Disk Utility Select the flash drive, go to erase. Linux, use Gparted. Install via sudo apt-get install gparted if your on a ubuntu/debian based distro.. Then try it in your S4 and see what happens. Maybe the partition got messed up and the S4 is goofing up when it goes to read it, or check partition table or something in a way where other systems might be okay with it still.

Thanks for the input. I did try as you recommended. Even going so far as to format in a galaxy s3- successfully ....a digital camera - successfully ...and my computer systems successfully....all able to read write and format.....galaxy s4 just doesn't seem to care....

Interesting. Well eliminated anything with the card itself or formating.
Have you tried any other microSD's in your S4?
If not I suggest trying that and see what's going on.
If it DOES work then it might be a issue with the card. If it doesn't, something with your S4.
It's either hardware (the microSD card reader is bad somehow) or software (Something in your ROM is messed up). If you want to troubleshoot it to the fullest extent you can do a full factory restore, wiping your phone completely, and loading stock firmware again and wiping \Data partition, as well as cache and see what happens. That would eliminate any software issue.

I have tried other cards and they all work fine. S4 can do everything with these cards. Format...mount...unmount....etc...
Just seems to be this one card in this one device....both card and device work well outside of each other...

There's your problem then. That brand card or something, or that particular card may have something funny going on with it.

I had the same exact thing happen to me yesterday. I was also having issues with my WiFi not working either.
I ended up doing a complete wipe of my S4 in cwm, Odin to stock, updating my software via settings and re-rooting. After doing that my WiFi worked and it would read the 64GB SD card I had.
Luckily, I had a nandroid backup from just a few days prior I was able to revert back to.

Aokp/aosp/cm roms/kernels don't support the exfat format.. So format the SD card to FAT32 to fix the issue check this out.. Lots of threads on this.

Your 64gb sd card is Exfat and a lot of kernels and roms do not support this. Format it to Fat32 and all should be good. But backup everything on your sd card before you do it

don't know how far you have gotten on this, but
i usually use sdformatter from web. i do a "full erase on", takes awhile, but cleans card well and always solved any card issues i had--

Final Solution Atrix 4g to the rescue
Finally put the SD card in my old atrix 4G and reformatted twice and now the card works!
Can't for the life of me figure out why nothing else could format the car sufficiently.

I struggled with this as well just now with my SanDisk 64gb card on my Verizon s4 running Jelly Beans... Solution was to format the card fat32. I did this by executing this file from the command line and issuing 'fat32format x:' after mounting the card obviously. Here is the file fat32format.exe It works perfect now Note: Don't format the card again on your phone or it will end up exFat and the phone will reject the card again.

[Q] External sd problems

Hi guys
I'm having some extremely irritating problems with my A500. It doesn't detect any external sd card I've tried so far. It says external sd is unavailable under storage in settings and the external_sd folder is empty in root/mnt. I've tried 3 different cards so far with no success. Anyone have a any advice for me on how to mount the card? I think the problem might be that it doesn't get mounted when I insert it. I can't root because the GingerBreak mod that's been posted needs an external card to work. So maybe some advice on how to root some other way? Then I can try restore a stock image and see what happens.
I had to insert mine and then reboot the tablet for mine to show inside of a file manager.

Hey, thanks for the tip. I forgot to add it to my original post. I've tried rebooting with all 3 of the cards I have. I'm starting to think it's a hardware problem...
Have the cards you're testing been formatted NTFS or FAT32? If NTFS they probably won't work without some help.
The stock device only deals with FAT32 mSD cards; I haven't tried the NTFSMount app from the Dev forum on an NTFS-formatted card yet, only USB devices.

Hey. I've formatted the cards multiple times, to FAT32 every time. Might try exFAT tomorrow just to see what happens.
exFAT didn't work. Not that I expected it to, lol. Maybe the GingerBreak apk can be modified to use the usb storage instead of the external sd. Any idea where I can get the source code to take a look at?
If you've tried multiple cards, all FAT32 and all work on other devices, I'd return the tablet while you can, sounds like a hardware problem indeed
Slight problem with the returning, lol. I live in South Africa and ordered my tab from the USA since my own country is so backwards. I don't really mind not having an external sd card, I just wanna root again since almost all the apps I use need root. I'm considering returning, even if it's gonna take a lot of effort, time and money...
EDIT - Another reason I can't return it (and this is a horrible thing) is that SuperUser Permissions is still installed. The recent update made me lose root. So I'm kinda stuck with this app that's proof that I voided my warranty. The only way to get rid of SuperUser is to use some apps that all need root. To get root I need the external sd to work. To get that to work I need to send it for repairs. A very messed up situation
I'm almost positive that it's a hardware issue now. Even when I try to do an update.zip from recovery mode it can't find the file even though it's on the card. Let's hope they don't see the SuperUser app when I return it...
I thought about maybe waiting for Acer to release an update that will unlock the bootloader. But since the SD card slot isn't working I won't be able to install the update. That so much depends on one little slot amazes me. If you wanna know what the single point of failure for an Android device is, look no further.
I know some android tabs came out without external SD card support. I live in the uk and have a 32GB version and the SD card worked out the box. Maybe you have to wait for an update. Just my 2c though. You won't need an external SD to receive OTA updates though.
Sent from my A500
Here's an image of what recovery mode says when I select Install Update from external source. Seems the system can't mount the card. Sigh
I like that message at the end.... "Install from sdcard complete."
You had rooted before the update, which means it had to have seen the sdcard then. So it's unlikely that the hardware just went bad. Are the sdcards your trying of different sizes, classes, and/or manufacturer?
I'd go with the same sdcard you used when you rooted before and reformat it using the HP USB Format tool. Selecting fat32, of course. And don't select quick format. See if that helps. Sorry if I missed somethiing relevent above.
Here's the link to the HP first tool. http://download.cnet.com/HP-USB-Disk-Storage-Format-Tool/3000-2094_4-10974082.html

Lol, the "fake it till you make it" strategy. Fail Google.
I've tried it with the original SD and two other ones. My guess is some app tried to mount the external SD in /mnt/sdcard and messed up some associations or dependencies or something.
I'm amazed. After everything I've tried it suddenly worked. I was busy in settings and accidentally selected storage. And there it was in all its glory... A working external sd card! I'm rooted again, backed up and ready to roll!
To anyone finding this thread hoping for answers for a similar problem: It was a hardware problem indeed. I fixed it myself by opening the tab and bending the MicroSD slot's pins back into place.

64 mini SD card damaged?

I bought a brand new class 10 SD card and I tried it with the s3 and worked fine. When I got my new galaxy S4, I format the SD card and put it in the St and again I format it from the phone itself. I put my picture and song. Then when I turn the device off and back on again it will tell me the SD card damaged need format. But when I go to setting, Storage. And mount the SD card it will work just fine.
Can anyone tell me what is the problem? because it is really frustrated

Try formatting on your pc with exfat and then reinsert the card in your s4.
Have been getting that on mine also. I reboot and then it works fine. Not sure I actually thought I had damaged mind by maybe not

This happens a lot on my S3 and the only long-term (but not permanent) fix I could discover was formatting in the computer like the guy above stated. I always keep a backup of my phone ext. sdcard on my laptop to make sure that if it happens and can't get it to work I still have my data, I recomend people to do the same.

I also have been getting this problem with a 64 gb card. It must be a bug. So far, I just reboot and it seems to read it fine. I noticed it also throws me into safe mode on the phone if I reboot too often. I'm not sure exactly how it is triggered.
I had the same issue, it happened when I removed my SD card from my S3 without "safely ejecting" it from the Storage menu. I plugged it into a computer, and went to a command prompt and ran "chkdsk d: /f" where "d:" is the letter of the SD card and it fixed the filesystem and all of my files were back and my card was perfectly usable again.

[Q] LINK2SD Broke efs on my SM-G900H

A- I recently installed Link2SD on My rooted Galaxy S5 (SM-G900H) and everything seemed ok. The app asked me to reboot my phone, when I did my phone stuck on the SAMSUNG Logo screen and FACTORY RESET/Wipe data didn't work. I even tried emergency recovery with no luck (Error mounting efs). I fixed the efs issue and I re-installed the stock ROM and re-Rooted my device.
I didn't re-install Link2SD anymore because I'm afraid it may break my phone.
1- What is the maximum size of the ext2 partition?
2- Does it work on SM-G900H without issues?
B- Despite what they say about Kitkat and that you cannot move your apps to SD card, I have the option on my phone to move (movable apps) to SD card and that's good enough for me. I purchased a SANDISK Extreme plus 64 GB SD card (Which is formatted in exFAT by default). When I move apps to SD and reboot my phone, all the apps on SD disappear and my phone starts acting weird and apps crashes. Maybe it's because of exFAT but I'm sure the SD card is fine and not broken. That's why I wanted to try Link2SD and see it it solves the problem.
Have anyone faced theses issues? Anyone know a solution for these problems? I appreciate any help.
Bump... Me too!

Yes, I am having a very similar problem and I also have the 64GB SanDisk Extreme and SM-G900H and rooted.
Did you ever find a resolution?
My extSD seems to come and go. The last time I uninstalled the last 2 apps and it was good for 24 hours. Put I just pulled it off the charger and it started acting up again.
I cleaned the contacts, chkdsk'd it on my PC (everything reads fine) and rebooted a few times but no luck.
This post had some good recommendations but cleaning contacts, etc. didn't help me.
I was going to try an OTA update but it seems that I need to un-root first. That's my next step -- starting over.
Try FAT32

You SD card is formatted with exFAT? Try formatting it with FAT32. I didn't try it yet because I can't use my phone since my EFS partitions are gone and my IMEI code changed to 004999.... (Generic IMEI code).
Let me know if this solves your problem.:angel:

64GB will for sure need to be exFat -- FAT32 can't access all the space.
This is a good utility to reformat and fix it OR you can use the cmd level commands.
For me, I am able to use it intermittently now -- seems like it will work for hours, even days, then have a problem when I pull it off the charger. Of course, I woke up this morning and it wasn't working AGAIN.
I am on the phone now with Samsung tech support to see if there is a log somewhere that can give me more information about what is exactly failing. I did use this same card in 2 other Galaxy S5's (AT&T and T-Mobile versions) with no problem. Maybe I ruined the card when I had it in my wallet?
FAT32 - I was wrong.

I was wrong. FAT32 CAN access all the space. I reformatted with FAT32 using the fat32format program and still have the same problems.
Furthermore, it happens with and without root -- I've reflashed a million times now.
At this point, I think that I just got a bad card reader in my unit because the card went off just by tilting the phone sideways last night (clean install, no root, no apps).
Good luck to the original poster.

galaxy S4 microsd card problem

Hello
I have SanDisk 64gb microsd. I have not done anything to the phone and now periodically the phone stops reading the 64gb card .It does not say unmounted just when I check gallery the photos are not there and I have to restart the phone.
I have a rooted 4.3 ROM..The only thing I can think of is ES file explorer potentially caused issues. I noticed things acting weird after I used it when I do heavily.
Please help. Any and all advice welcome. Thanks
Tried to re flash a nandroid still issues. I noticed in general my touchwiz is running so slow. I flashed sacs red theme about a month ago. Not sure if that had anything to do with it. Should not have.
It will reread it when I remount it or reboot. Not sure specifically what is causing it though.

Have you tried searching the forums for sdcard fix? Google it? There have been issues with 4.4 and sdcard reading issues. Also downloading foldermount from the playstore has helped others with issues. If all else fails reinstall rom.
Sent from my SPH-L720 using XDA Free mobile app
I searched on Google and there is not really a concise answer as to why this happens. It is a very ambigious issue, however; it seems to be a reoccuring issue with SanDisk cards and 4.4 KitKat ROMs.
What I did was completely flush out and re-installed both custom recovery and my ROM to 4.2.2
It is disappointing because I really like my Samsung Galaxy S4 phone and you'd think upgrades mean better quality product when it has not. 4.4 KitKat ROM is not that good. I don't like both CM and TW versions of KK. One feature I do not like with TW KitKat is the inability to hide icons. There are also issues with battery drain and free hotspot mod.
I don't know what is going on. When I plug my phone into the computer I can access the SD card. When I check the phone it is not reading the SD card. Don't know what the problem is.
Have you tried a different SD card? That would help you determine if it is specific to the card or potentially a phone issue.
What I will do is try and format the SD card with the phone, then put everything back on. So far, I have isolated it to ESFile explorer. Initially I did not update the apk and thought that would work. It did not.
Here's what has happened:
I use ESFile explorer to access the SD card. Then when I went into clockworkmod, I tried to delete a nandroid copy I made. It says 'failed to delete'.
Then the ROM and sdCard do not work correctly anymore, so I have to wipe and re-flash an old nandroid.
Makes me wonder if something is corrupted in the SD Card. Everything used to work fine, but now whenever I access the SD Card with ESFile explorer, even the old version of it, it causes issue.
There is a problem with some Sandisk SD cards. Evidently there was a bad batch. I had some of the same issues. My card was bad. I went to Sandisk's website and they replaced it for free. I was without my card for a week but I got a new one and everything seems to be working fine now.
Can you explain how you did this ? So an update on my situation. I can read the sd card but it will not format and nothing can be written to the card. I tried using recovery and touchwiz to format and it fails.
Can access what is on there but cannot write or format anymore. Any ideas ? At this point I swapped to a new SanDisk card I had lying around. Don't know what to do with the old card

I assume you are asking me how I got my card replaced. I did some research and found the issue mentioned here on XDA as well as on the internet. I went to Sandisk's website, http://kb.sandisk.com/app/answers/list/kw/microsd microsdhc/, and did some more research. I finally contacted their customer service and they told me the process for getting the replacement shipped. If I were you I would just contact their customer service on their website and let them run you through the process.

[Q] SD Card blank or has unsupported filesystem

Hello guys,
I have a Galaxy S5 G900T running the AllianceRom 3.1 made for G900F. I use an external SD Card SanDisk 16GB and since yesterday I never had a problem.
So, now I'm experiencing this error: "SD Card blank or has unsupported filesystem" on Notification Panel. When I click on it, android asks me if I want to format the card, I click OK, and at the end the same problem occurs.
Things I already tried to do:
1) I tested the SD Card into another Galaxy S5 and it's running OK without the problem;
2) I formatted the SD card (full format) on a windows computer. Windows recognizes it, and it's running OK;
3) I checked the file vold.fstab on /etc folder and it has the same content as another Galaxy S5 that is running OK the SD card;
4) I re-flashed the AllianceRom 3.1;
[EDIT 1]
5) Tried to wipe the SD Card using TWRP Recovery (as image 1 attached)
6) Tried to partitioning using TWRP Recovery (as image 2 attached)
[EDIT 2]
7) I bought another SD Card, a Samsung 64GB and when I insert it on device I don't get this error, but also not able to mount, it doesn't even recognizes the SD card.
p.s. I searched a lot on XDA, even on Google, and those was the possible solutions I've found, but didn't work for me.
Does someone experienced this problem and was able to fix?
Does anyone knows another alternative that could work?
Thanks in advance

Copy the content of the sdcard to the pc and format the card on the phone itself, that should fix the issue.

Have you tried another SD card in your phone? EDIT: Nevermind this bit
When you plug the SD card into your handset (do it while it's off) Does the SD Storage show anything?
You could try formatting it in another handset if you have the chance then try plugging it in.
Are you using stock Sammy firmware? Or have you installed a custom kernel? Could be one of those playing havoc with your device if so, back up and revert to stock if you can, retest the SD in there.
Test to see if you can retrieve data from the SD card, i've found that although SD cards show up in windows, when I attempt to copy data to the PC it fails, when I say fail I mean it stops progressing and doesn't copy, particular files appear corrupt.
You could also do a chkdsk /f /r via windows on the SD card, or even a general error check.
chances are one of these things will be the culprit, if none and it's still working in another phone and other cards are working in your device then i'm stumped.
Good luck
I would try philz recovery, i had all kinds of problems with twrp on my note 3 and s5 until switching. Not knocking twrp this is just my experience

You could try formatting it in another handset if you have the chance then try plugging it in.
Are you using stock Sammy firmware? Or have you installed a custom kernel? Could be one of those playing havoc with your device if so, back up and revert to stock if you can, retest the SD in there.
Test to see if you can retrieve data from the SD card, i've found that although SD cards show up in windows, when I attempt to copy data to the PC it fails, when I say fail I mean it stops progressing and doesn't copy, particular files appear corrupt.
You could also do a chkdsk /f /r via windows on the SD card, or even a general error check.
chances are one of these things will be the culprit, if none and it's still working in another phone and other cards are working in your device then i'm stumped.
Good luck

Hello mate,
Thanks for answering

I get the same problem: SD Card blank or has unsupported filesystem

I tested the SD card on another device and it's working fine, also on my windows pc

I formatted my device right now and installed Samsung stock firmware with stock kernel. I also tried to get back to stock recovery, then installed CWM and TWRP, but the same problem
I'm starting to think this is a hardware problem, because I tried everything and nothing happened.

Quite an odd one that, i'm a little stumped.
did you try error checking on windows? OR even a format in a different handset? OR a different card in your phone to see if to see if it reads?
On the other hand if the phone isn't that old, return it, 28 day swap should be good if you're in time, otherwise it's back to sammy.
sorry I can't be of more help m8.
Same problem with GalaxyS5 and 64 GB card
I am having the same issue with a 64GB memory card in the Galazy S5. Blank or unsupported file system.... doesn't format in phone. works great on PC and even on old Motorola Razr phone, format exFAT and FAT32 tried but the phone doesn't care.
please help, I first bought a sandisk card and returned it because i hoped the same brand SAMSUNG would work, nope nope...
HEEELLLPPPP
Thanks

Same problem with GalaxyS5 and 64 GB card
Have you found a solution to the OP?
I have an S5 too and it's doing exactly the same. I tried a 64GB Sandisk and Samsung cards, both work flawlessly in PC, MAC and even a different phone. WTH???? My 32GB Sandisk works well in the GAlaxy S5 too, I am about to see if it blends....

Hello guys,
I have a Galaxy S5 G900T running the AllianceRom 3.1 made for G900F. I use an external SD Card SanDisk 16GB and since yesterday I never had a problem.
So, now I'm experiencing this error: "SD Card blank or has unsupported filesystem" on Notification Panel. When I click on it, android asks me if I want to format the card, I click OK, and at the end the same problem occurs.
Things I already tried to do:
1) I tested the SD Card into another Galaxy S5 and it's running OK without the problem;
2) I formatted the SD card (full format) on a windows computer. Windows recognizes it, and it's running OK;
3) I checked the file vold.fstab on /etc folder and it has the same content as another Galaxy S5 that is running OK the SD card;
4) I re-flashed the AllianceRom 3.1;
[EDIT 1]
5) Tried to wipe the SD Card using TWRP Recovery (as image 1 attached)
6) Tried to partitioning using TWRP Recovery (as image 2 attached)
[EDIT 2]
7) I bought another SD Card, a Samsung 64GB and when I insert it on device I don't get this error, but also not able to mount, it doesn't even recognizes the SD card.
p.s. I searched a lot on XDA, even on Google, and those was the possible solutions I've found, but didn't work for me.
Does someone experienced this problem and was able to fix?
Does anyone knows another alternative that could work?
Thanks in advance

Same here. My phone already went in for repair for this and the front camera ring falling issue. Mine was preordered and shipped at launch. It worked a few weeks and now has stopped again. Simply won't recognize any SD cards. I tried an old 2GB, a Kingston 16GB, a Lexar 32GB from my GoPro, and a Sandisk 64GB. All cards work elsewhere, but my S5 never indicates anything is inserted. This is my first Samsung, and it might be my last. I never experienced issues like this on an HTC.
Any progress here? I just got a sweet 64g card Samsung because my others have worked well BUT...
S5 Blank SD card of death. ....
