I tried researching this but wasn't successful finding same exact problem or solution. I'm on 4.4.2 Baseband N900TUVUCNB4 rooted with stock rom and ext sd fix. Everything was working fine until recently. My external SD card has inexplicably become read-only, both on the phone and on my desktop. I first noticed this last week when the phone camera began having problems writing to external SD card, and now I can't sync music to card. I've tried formatting on the phone and desktop, both quick and full but no dice. On the phone, I am able to delete individual files or folders but they reappear. On the PC, I can view but get write protect message when trying to format. Anyone else come across this or have suggestions?

Happened with me once with a different phone/OS. Weird thing is that it was only for a particular SD card. I put a different card and it worked.
It turned out to be a problem with the card (dunno how thats possible though).
What's the brand of your SD card?
I have the exact same problem with my SGNote 2 and SanDisk 64gb micro SD card. First I lost some pics I have taken that day. I searched through with a file rescue tool but they were nowhere to be found. Deleted files reappear, and the ones I copied from internal SD dissappear.

I had same problem. But I fixed this problem by formatting my SD card via PC. It is very bad to me Because I lost my some valuable Docs:crying:
Try file recovery softwares, you might recover it.

It's a SanDisk 64gb class 10.
Glad to hear I'm not the only one. Maybe we can share the solution when we find one. I'm using internal memory in the meantime for new media files, but frustrated that I am not able to use the rest of the memory available on my card.
SanDisk works fine for me, maybe your sd card is a faulty one, let's wait for a while here and maybe someone could answer your question and hopefully solve your problem

Thanks, Lorettaa. It seems like that's the only option right now, since I can't find any other info about it on XDA. I know Kit Kat has that design "flaw" where apps can't write to an SD card, but I can't even write to it, modify it or reformat it on a PC. I have full read access to every file, just can't do anything else

I have the exact same problem, i tried many options , used some softwares in windows to format , wipe, fix, modify. nothing works.
One possible reason for this problem is file system errors , which can be rectified using the 'error checking' option in windows and 'fixing the file system errors'
But that doesnt solve my problem, even after formatting using advanced softwares, the sd card is the same - no files deleted, no files added...
The fat as well as ext4 parition is not formattable now in anyway.so the possible conclusion is 'sd card is going to fail'.. Take a backup before you loose the read capability.
Recuva is a good, free tool (from the people that make CCleaner) to deleted recover photos.

And one possible reason for a false error condition is a corrupt system. This is normally an unlikely possibility but it is very likely on devices that have had partition images written to (i.e. a flashed ROM). If you have done all you can to the SD card and if the errors are not only on one SD card then wipe everything and load a backup. If you still get errors then wipe everything and revert to stock to see if they still occur.

I've been searching all over for a couple days now and I can't find any solution only people with similar but not exact same problem I'm having. Out of the blue a couple days ago the fat32 partition on my 32GB class10 patriot SD card unmounted and won't mount at all. However the ext4 partition mounts just fine and continues to work as it always has. I also can't plug the card directly into my PC because the adapter that came with the micro SD card appears to not work. My PC doesn't think there is an SD card in it. I tried it with a known good SD card (the 16GB samsung SD card that came with the phone. Which when inserted into the phone mounts and can be used like expected. No new apps where installed or changes made to my phone or the SD card before it stopped working correctly. The same apps and what not have been in use for as long as I have had the 32GB SD card. In fact the currently in use version of CM10.1 has been is use for the last month with no issue regarding the SD card. When I remove the card a notification shows up telling me to insert an SD card. And when I insert the 32GB card the checking SD card notification shows up an a second or two after the SD card is safe to remove notification shows up as if I had told it to unmount the SD card. If I tap on mount SD card in settings the same thing happens. And it also happens after a reboot. CWM can't mount the SD card either. What can I do to fix it so the fat32 partition is usable again?

Have you tried formatting the SD card in recovery?
As I said I can't mount it with CWM either. The card contains the data for my mSecure passwords as that app was forced to the SD card due to JB changes in android so I can't format it until I can recover the data on it. I need a solution to access the data before I can reformat it assuming that it needs to be reformatted. The SD card was supposed to be this fail safe thing and I didn't need to make backups of it as it was the backup storage stuff. So now I'm all freaking out because I can't access it for all the backed up data on top of the data for one critical app that was forced to reside on it. The good news is that only a few apps data is effected by this the bad news is those apps were all very important. I just don't understand why this has happened. And if using a cloud source such as box will be any more secure and safe than using the SD card in light of this; now I don't trust not losing data in the future on a source that was supposed to not have this sort of thing happen.
Maybe the SD card just went bad. Sorry I couldn't be of more help.

No problem, it's a problem no easily solved, and is a long shot finding anyone who will be able to help. I looked at dozens of sites and forum threads and all sorts of other stuff from goggle searches and couldn't find a solution to get it to mount in either the phone or on my PC to recover the data from it and find out for sure if it is a bad card or not. It might still be under warranty. If it's not I'll be ticked considering how much it cost and how little time I've had it.

Try installing Recuva on your PC, if this program doesn't work for you then you might wanna try another more advanced recovery program like R-studio v6 (Shareware) which is easy to use since it's GUI based.
or testdisk-6.14-WIP (Freeware) which includes testdisk_win.exe for partition recovery and photorec_win.exe for files and media recovery, but it's kinda complicated since it's based on Command Prompt or DOS! so you need to google for a guide for how to use it.

Wow I somehow never got notified of this post seeing as I'm just now noticing a reply from months ago. Yes I still can't mount the SD card. I took it out and returned to the stock one that came with my phone. I still have the card as I need to recover the data from it and if not possible wipe it somehow so that I can warranty exchange it. Please do let me know what your solution is so that I can try it and see if it works.
Refresh my memory on what the problem was. This was a while ago lol.

The SD card won't mount in my samsung epic and my windows PCs. This was a sudden without warning signs and with no apparent cause. One moment it was fine and the next moment poof. I was looking for a solution to gain access to the files on it to recover whatever I can and if possible repair the card so that it works again. Assuming that it's not a failure of the card itself. It is within the warranty and well within the life expectancy of it. So I suspect it is not a failure of the card itself. I have the option of using ubuntu or other USB stick bootable options for tools as needed.
Hello All,
Two weeks ago I bought a new Samsung MicroSDHC Pro 64GB Class 10. Kinda from the beginning it wasn't working how it should.. I formated it EXT4, exFat and FAT32 but all give the same problem.
For example; I copy a flashable zip on my external sd card, copies just find, but as soon as I try to flash from the external sd card I keep getting an error and the flash failed, almost instantly. If I copy and flash the same file to my internal sd card, it works just fine and no problems what so ever.
I tried formatting it through Sense, GPe and even a USB card reader.. all give me the same issues. I can even make a titanium backup and it seems to work. Tho, as soon as I try to restore from it, it won't find the files from the backup..but when I check the external sd card on my pc (phone connect to pc by htc usb cable) the files are there and it seems the correct size. But when I want to try a batch restore in titanium backup, and I look the phone for backup folders, it finds the foder.. but when I actualy wanna start the batch recovery, it only sees 1/2/3 apps to restore, even tho there are over 70 apps to restore.
I'm at a loss at the moment, I feel like I've tried everything and nothing seemed to work. This is what the error looks like when trying to flash from external sd card:
E:Unable to open zip file.
Error flashing zip '/external_sd/blablabla/blablabla.zip'
Updating partition details
Hope anyone could help me with the issue.
Thanks in advance<3

I've seen in the past that 64gb cards have issues with formatting unless formatted in windows as Fat32 - mine did
As soon as I did that it worked.
Have you checked it to make sure it's not fake? Where did you buy it from & what is the formatted capacity? Should be like 59gbs and change

Got it from a dutch website, through a person, not a company.. it had all legit packages etc, but how can I check to be 100% sure that it's real?
My computer shows it has 62,4GB total capacity.. reading it from card reader. Sounds wrong?

Deffo wrong. Sounds like a fake. Capacity is 64gb. Available is obviously lower after formatting. Legit packages mean nothing - take a look here

Hello, I have flashed the JellyKat ROM v5 on my NoteII and got a new sd card (ADATA 32GB) from ebay, the card was sealed so I hope I wasn't cheated, but randomly I see these things in my DCIM folder and I can't write to the card and the phone seems to not read the media on it music photos everything, and I can't install any apps on it or update existing app or even create a folder through the default touchwiz My Files.
I tried to format the card on the PC but can only do quick format because it loads and loads and then say windows can't format this, I also formated it via the phone it worked for a while and then stopped working again, now I don't put a card in the phone.

Yup, I also faced that kind of problem before, simply run KitKat SD fix, grant root and let the app patch the platform.xml. Reboot and try again. It worked for me. :good:
Ever since I converted to GPE for 6.0 then back to Sense (5.0.1 stock, rooted) I have been facing problems with my external SD Card. I know that Marshmallow handles External SD Cards a little bit differently than other versions of Android, so I decided to backup everything to my computer and then have my device format the SD card inside Sense but it still did not work.
For one thing, I can no longer backup from Titanium Backup to my External SD Card since it says "this folder is not writable" and whenever I try to delete or move anything inside ES File Explorer, a message comes up saying "please choose the root directory of ext_sd card ...." and when I try to, I get a "Documents Force Closed" error.
Any ideas on what I could do at this point? Should I try formatting the SD Card on my computer using a SD Card reader instead? I am using a Mac, by the way.
Thanks for your time.

Interesting. I never knew that was even a setting in TiBu either. What I did was a little more involved. Had to edit /system/etc/permissions/platform.xml) and add a specific entry to allow a group permission to write to external storage. Check the attached image. Of course I added the highlights.

I think you missed what they were talking about.
What you suggest is not valid for android 6.0 marshmallow.
Only workable for lollipop and lower.
You're right about that. I'm not on MM yet (Verizon...) so I hadn't a clue.
I have a PNY a 64gb class 10 had this card since the phone came out,
I noticed that you could update to marshmallow by LG Bridge, so i did so, everything went smooth, however i noticed everything used to be saved on my sd card then was saved to my phone and its not reading my sd card at all.
Ive formatted the sd card through my phone by storage-sd card-settings-format- while im doing this at 20% it will say sd card is ejected but then proceeds and says its been formatted correctly.
However the phone will read the sd card only in SETTINGS-STORAGE, it will read the files on the sd card, how ever if i try and play music/movies it will not read it through my apps like mx player/poweramp.
Apps like app manger 3 - which i use to transfer apps to sd card will not read my sd card at all.
Ive tried and formatted the sd card through my phone only around 5 times and still the same problem.
any help

i would check the permission thing just to make sure.. here is a how guide for that
i dont know what you can do more than that,you could maybe try to check another microsd to check if it didnt ruined the file system on it or(or simply if the sd you have is broken) or to if it is really a OS issue...
but as it seems for now a lot of people having problem with the sd part of marshmallow...

ive tried to do permissions but it wont allow to change to sd card,
Ive reloaded phone and before it comes onto my home screen says mount my sd card, ive gone into storage - sd card- mount, restarted phone but again the same issue.
When im in camera mode the phone allows me to select where my photos will be saved (onto sd card), i can go into settings_sd card and read everything onto sd card, however its just moving apps onto sd card it will not allow.
Ive read online saying marshmallow may only allow apps to be saved on internal memory now due to previous versions off OS- was a problem with viruses being attached on apps which were saved onto sd card- was the main problem. Could it be this?, marshmallow doesn't allow this.
Use TWRP to format, that was the only solution to get my 128 GB sd card working after update again. The integrated format function always tell me success while notification said card damaged. After formatting with TWRP everything worked again
Edit: Are you sure you flashed correct patched kernel as this can disable vfat reading? Look here in forums, there is a thread about different version names for different countries (e.g. German V20a is polish version V20b)
