Hello world!
A very strange issue have just happen with my Lenovo phone. The SD card suddenly became unrecognized, only by some of the apps. the card itself is OK (PC tested, and the problems occurs with any card), listed properly under "storage" menu, and accessible by files explorer. But, when i open the camera or photo gallery - i recieve the message that "no SD storage". The strangest fact is, thar on the background of this message in the gallery, it shows up thumbs of images stored in the card...
Phone's internal memory has been repartitioned with METEOS app, to disable internal SD and increase internal memory, but everything was fine a long time until now.
I tried to recover the initial state of the phone. Did full format by Flash-Tool, the loaded on it an official chinese stock-rom, in order to recover its initial internal memory partitioning.
Then I upgraded it to CWM recovery and my previous custom ROM (Lambda) and everithing was OK, even the SD was detected. But then, when I tried to make repartition with METEOS app (after which i had to modify the actual code lines in Void.fstab, as instructed after METEOS using), BOOM! again the is'nt recognized only by camera and galley!
What could have happen? everithing worked fine more than a year
Update:
I have found that, though the SD is mounted in vold.fstab to "Storage", in the mnt folder it is still listed under Storage2.
How could that be?

Hello everybody,
I experience the following problem for a couple of days: my GT-I9300 (stock ICS, updated by Samsung some week ago) has a SD card (16GB) in it, which I could read from AND write to from my Win7-Desktop until some days ago. No, for some days, I cannot write anymore to the extSdCard as well as to the sdcard (phone's memory, 32GB). I cand read all right, but no writing. Any file I open, opens "read-only", and also no copying to the card is allowed, either. Even updating Kies and all its driver's didn't bring any improvement (actually, updating MTP driver caused some problems). Does anybody have any idea what to do?
thanks for your help
I have exactly the same issue as you, at the very beginning, i notice this problem when i was taking photo and said my sdcard is not accessible, it then changes to use internal storage.
Let me list out my symptom and solution:
Symptom:
1. The sdcard looks fine, no special error thrown during android startup.
2. Just after startup, i am able to write file /copy file to the external sdcard
3. After a while, the external sdcard becomes read only. I can view/copy files from sd card, but not write/copy file to the external sdcard.
4. No apps can modify the files in external sdcard
5. By using ADB shell, type mount, and you will notice the /extSdCard is mounted as "ro", which means read only.
Description:
If you have the above symptom, your external sdcard probably have some problems...
When I was checking the mount details on step 5, i noticed that the default options is onerrors=remount-ro , it looks like the external sdcared is remounted as read-only because it has problem on external sdcard....
Solution:
I put the external sdcard to a Windows PC, and run scan disk (right click the drive >"properties" > "tools" > Check Now).
It really find problem on the FAT of the external sd card!!! It fix automatically and my external sd card is working fine now.
In my case, it doesn't need to root or format the sdcard.
Good luck!
I wanted to install an app called "Root External 2 Internal SD" to see if I can extend internal space with some space from SD Card. But It moves all SD Card files in internal storage, and it keeps doing that for everything that goes in SD Card. I tried to hard reset my phone, but it still do the same thing as before. So I installed LG Mobile Support Tool to restore the stock system. After that long waiting time, when my phone starts, nothing happened. It was like I just restarted. My settings was the same and files and apps too. I tried that without SD Card too, but same result. Also from that point when I installed that app, scanning media storage takes too long, like 5 minutes, even without SD cars inserted.
I have Windows 7 x64.
Any ideas to restore my original system?
EDIT: I found LG Moblie Support Tool logs. There is the log: pastebin.com/dffcgNeE
P.S.: Sorry for my English.
So here's the situation. My sister has a Galaxy S2 which is rooted and has CM11 Carbon rom on it. She's been using it for months now without problems. One day she comes to me and says that her songs are gone so I open up the storage to see whats up. Apparently, the storage wasn't showing up in the settings and it only had an option to format internal storage. I checked with a file manager and it also turned out to be just like an empty folder. Tried to connect it to the pc but it also just shows the external SD card and not even recovery works, returns the can't mount message. I figured the storage is not dead but rather not being mounted as the system and app storage, and the phone itself, are working fine, since those should also be taken from internal memory? So my question is, what's going on? How can I recover the files from it?
Hello,
when inserting an external SD card, the internal memory card is then mounted as sdcard1 and the inserted external card is mounted as sdcard0. So Android starts writing a lot oft data to the external SD card.
How can I avoid this? Android should not touch the external SD card. I want to copy pix, music and backup manually to it.
Any suggestions?
Hi just go to settings =storage and then change default write disk to phone storage

Hello,
and you have tested this by yourself? If I insert an external SD card, switch to "default write disk to phone storage" and delete ALL data on this SD card, Android
immediately starts to write to data on it:
The folders "LOST.DIR", ".thumbnails" and "Android" are created. In the folder "Android" there is the folder "data" with several App-Data in it.
Even some Apps like WhatsApp start to write data to the external SD card.
So, switching to "default write disk to phone storage" does NOT keep Android away from writing data to it.
For example, on my Galaxy Tab Pro 8.4 the external SD card is mounted as "sdcard1" and no files are written to it automatically.
I browsed the web for hours, but did not find any solutions for this problem. It is not a big thing, but it is annoying.
:crying::crying::crying:
I have the same problem also on an old smartphone with MT6582 processor and Android 4.1.2.
It's an old problem, I think that it's a way of manage memory for smartphones based on MTK processors and there aren't solutions.
But I would like this to be denied
What about changing sdcard1 and sdcard0 , in the mount point file:

You must be root.
When i have time to root my phone i will try.
I am having the same problem and it is very annoying. Why can't Android leave alone my Sdcard? I only want to storage music and some files there.
@yascooluk
Settings =>storage => default disk write storage "Phone" has no effect. Lots of Apps point to sdcard0, which is now the external sdcard.

This Solution worked for Android Versions prior 4.3. In Android 5.1 there is no vold.fstab file, and swapping mounting points works differently now, but i didnt' figure it out yet.
Yes you are right, fstab is in boot.img in lollilop, if I believe what I read ;
http://forum.xda-developers.com/showthread.php?t=2426804
Maybe try to unpack and pack boot.img:

Sorry I have no time to work on my device , i have not already rooting it, and the internal memory is enough for me.
I've managed to root my device, but i'm not skilled enough to do this boot.img operation. Too many things that can go wrong. As the source code for this device was already released, I'll wait and hope until some developer can find a solution.
XinternalSD is the solution. Try it. regards

Greetings and Salutations,
I have a Samsung Galaxy J7 running the stock ROM and bootloader, Android 6.0.1, Kernel 3.10.49-9058927, with 16GB internal storage, and a 128GB U3 microSD card (not 100% sure of SD card speed, its above class 10), the phone is the 2016 version (subtle changes from the 2015 apparently) and has not yet been rooted.
I tried to enable adoptable storage to get a couple of apps to run better, but I want to revert back and seek a different solution, namely rooting and using Link2SD.
I tried the standard method of adoptable storage, and the option was not present in the storage screen on my phone. I tried using adb, and got timeout messages on the sm partition disk:179,64 private command. (Enabled USB debugging, accepted connections, installed samsung drivers, adb server daemon and shell all started successfully). Eventually it showed the sd card as corrupt. I popped it out of the phone, and deleted the partition on my computer, leaving raw, unformatted space on the card. I reinstalled the sd card in the phone, and the format as internal option was now present. I hit that, let it run and tried to migrate data afterward. Migrating always failed between 30 and 45%, and it showed me at 15.92GB or more out of 16GB used. I decided to revert back. I reformatted the sd card as portable in the phone, and it corrupted again. I did the same process, but elected to format as fat32 on my computer. Reinserting the sd card, it asked to format, so I did, as portable. The sd card appears to be back to normal, but I'm still at almost 16GB used on the phone. I tried to delete some music files that I have on the SD card as well, and they won't delete from the internal memory. It always says "could not delete" or "Delete operation failed". I have used the built in file manager, ES file explorer, and I believe I tried on my computer last night (it was getting late, but I remember at least trying). All fail to delete the files. I'm down to very few apps, none can be moved to the SD card, and I can't move much data otherwise. I harbor a suspicion that some hidden files are present on the internal memory, but I could be paranoid. I'm hoping to avoid a factory reset, but I fear that's the only option. I have a backup of the sd card, but not the phone's internals beyond what google saves in the cloud. I'm open to suggestions, and thanks in advance.
