[Q] External SD Card is not writable. Fixing permissions does not work or help.

I'm currently running Stock TW 4.1.1 because it just works SO well for me. I've not bothered to upgrade since I bought this phone almost a year ago now I think..?
I'm fully rooted though and I'm running the Note 2 keyboard etc.
Anyway I finally decided to try an upgrade. I tried using the Stock MOD 4.3 ROM which was MUCH slower then my 4.1.1 ROM so I Nandroided back to my backup.
I've noticed that my external 16GB SD Card is no longer working though. I mean, it works. I can access my files and open them BUT the card is not writable. If I check the file permissions I can clearly see it's not set right. If I try to change the file permissions in something like ES File Explorer or Root Explorer I just get errors about not being able to change permissions.
If I boot into TWRP and run the "Fix Permissions" this doesn't help either.
Again this is for my EXTERNAL SD Card, not the built in SD Card.

Have you tried backing up the contents of the sd card and formatting it? Either from within the phone's storage menu or another device.

No I have not. I wanted to see if there was a way to do it without formatting first but if no one has any other idea's, I might have to try that.

That would be my first move to rule out a potential hardware failure, assuming you have the means to do so without much trouble.

Well being that it started right after a Nandroid restore I'm thinking it's not hardware failure related but you never know.
I guess it wouldn't take too long to do that. I'll give it a go.

Yep that did it. I guess I was WAY over thinking the issue.
I'm able to save porn to my external SD Card again so that is a major plus!

[Q] External SD Card Read-Only Problem

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.

Thanks. I tried formatting through PC using windows and also tried using SDFormatter v4.0 but get write protect error. Thanks for the suggestions

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.

Anyone having problems with sd card on LG G3?

What do you mean, trouble reading or writing to the sdcard? Try formatting the card on the phone itself, that usualy works.

What are you trying to do with the card? it might be that you just are not aware with how Android Kitkat treats the sd card slot?

Probably......only File Manager can write or delete files on my sd card, Xplore or a different Manager can't, is it normal in KitKat?

Apps can only write and edit files that they themselves created on the SD card which is why third party apps are not working. It is to stop rouge apps deleting / creating / modifying files that they shouldn't be.

With files you mean system files or files created by you? You should be able to delete or move files with an alternative file explorer or you might try gaining root (towel root is easiest) to gain admin rights.

If you root your phone, you can remove the limitations that were added in KitKat.

Many 'newbie experts' who say that an 8 or 16GB phone is fine as you can move apps etc. to an SD card are finding out the hard way that KitKat restrictions prevent using the card the same way as it used to be in older Android versions unless the device is rooted.

I have been having the random removals of the sdcard. I have a 64gb ultra I card and it worked perfectly in the samsung i had before this. I have taken everything off it and reformatted with eh LG G3 and it still randomly removes the card. I have purchased another 64gb card and does the same thing.
Any ideas of a fix?

Someone else had the same problem and they did an equipment swap and the new G3 didn't have the problem.
So it might be the SD card slot itself or its interface and a exchange might be neccessary.

[Q] I really need help - SD card issues, T210 tab

Hi, i bought a galaxy tab 3 T210 a week ago, and i'm done, i'm tired of this, i put inside a new 32gb micro sd card and since i updated to android 4.4.2 there is no way to write in the card, it just became useless, there is no way to use it inside the tablet, that doesn't matter to me, the part what i don't get is i can't copy files from my pc to the memory using usb cable, i've tried everything, already rooted, used all of sd fix apps, installed the ''KITKAT sd card full access'' module but nothing, i just can format the sd and use it once, after restarting the tablet the sd card is only readable, i don't know what else can i do, seriously i'm freaking out and getting to the point that i will just throw the the tablet through the window and buy a new one, this is just useless and worthless
can someone help me? after days of searching i'm just like in the beginning

Your Tab must be rooted, you need an rooten Explorer ,than you must change The Platform.XML

when i try to put some files into sd card this pop up "The device has either stopped responding or has been disconnected.", but it still connected and i can read the files

that patch is only a partial step, you also need to edit your boot.img's init.rc entry for media_rw to set perms to 755
or utilize an init.d script to perform the same function, or to create a bind mount to link your external card to a directory
in /sdcard and access it that way.

The SD-Card works fine, everytime i format the micro sd it's ok and i can do anything i want in any device, write, delete, new folders, just when i plug into the tablet and restart it, the micro sd ends working as it should and now works as read only.

Have you tried my Nolekat rom? If it doesn't work with my rom, then you have either a bad card or defective device.

for those with the same problem.
I'm actually using ntfs micro-sd and the tablet stopped damaging it, i mounted it with ''SELinux mode changer'' and ''Paragon ntfs$hfs'' to recognize it, it's better than nothing, the only way to write in the micro sd is with my notebook and a micro sd adaptor, it's not the faster way but at least i don't neet to format everytime i want to transfer files from my pc

Problems with External SD Card

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.

@TarekElsakka - I know I'm bumping this thread, however I hope this is taken with leniency as searching for a solution took me a while and I hope this reply will help those who Google for the same problem.
http://forum.xda-developers.com/showpost.php?p=59278548&postcount=4 is what you need to read. You need to explicitly change your storage provider to 'DocumentProvider storage'.

@ThePurpleK thank you for your information! I actually forgot all about this thread, but I found this solution a while ago and it fixed everything for me. Thank you again, I'm sure it will be helpful to a lot of people since everyone seems to be facing that problem with MM.

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.
