I've noted a problem with SD Card permissions after updating to ICS. I am not rooted, and now that I have updated, it doesn't look like I can root now but the card appears to be Read Only for everything except the preloaded apps.
Any third party app (Astro, Chrome, etc) cannot save files to the SD card. I have to save the file on internal card and then use File Transfer to move it over.
I've found a few suggestions on how to fix it but it requires Root access. Does anyone have an idea how to change the permissions without Root?
Thanks in advance.
I don't think it's possible to change permission assigned to the sdcard2 (external sd), because the file you have to modify is in the system partition. It is possible if you have root permission on your tablet.
Bye ENx
You might use /mnt/sdcard2 instead. At least with ES File Explorer this works fine. Try to contact the developers of your Apps if they don't provide a configuration option.

That's not going to help. In ICS, the external SD is still mounted at /mnt/sdcard2, but now its mounted read-only for non-Sony apps. You would need root to remount the SD card if you want rw to sdcard2, so I've got nothing.

I'm not sure if I understand correctly. I successfully copied a file into /mnt/sdcard2 with ES File Explorer. A copy to /sdcard2 fails.
I'm at ICS.
Information on this issue: "Is Google blocking apps writing to SD cards" (I'm not allowed to post link)
Thanks for the suggestions. I've tried the /mnt/sdcard2 option but it still failed. I have several ways to work around it but it's just annoying that it can't be easily fixed.
I read where ICS 4.06 fixes this but no telling when Sony will release an update to that. I will probably just wait until I can root the device.
Thanks again.
i'm writing to sony support, it's really stupid that i can't access my SD with the file manager i like !
Won't see sd card
Hi guys, i have a problem.
I bought a new sd card and tablet won't see it.
But in phone that sd card could be read.
What is the problem?
I tried to format sd card but the same.
Also the sd card from phone could be read in tablet, that is strange
Make sure the SD card is formatted in FAT32 so the Tablet can read it.

Hey guys,
Sorry if this is a dum question but i cant figure out what the issue is. I have a 4gb micro sd card in my Vegan Gtablet. I can go into es explorer and see the sdcard 2. I have been able to create a folder in that sdcard 2. When i take it out the folder is gone so i know that is the place i need to be. Anyways When i try to move media files from sdcard to sdcard 2. It gives me a error and wont move it. What am i doing wrong or am i missing something?
Any help would be great. Thx.
have you tried using Root Explorer to make the folder r/w? I'd like to understand the difference between the sdcard and the sdcard2. I have my gtab (vegan) mounted currently to my pc, and i see sdcard as empty and sdcard2 with files, but when i had no card in, the sdcard had the contents and sdcard 2 was empty.... Anyone have insight on these folders?
sd card2 issues
I am also running vegan on my gtab. my computer can not see sdcard2 (external card) but I can transfer files to it via usb drive using adao file manager. when I shutdown my gtab the files dissapear. Is there a fix that will allow us to use the sdcard2? Any help is appreciated thanks in advance.
I went and used root explorer and gave me error that its a read only system. Im trying to move media files from my built in gtab memory to the micro SD card? How can this be done? Help !!!

There should be a button at the top of the file list to change from RO (Read only) to RW (Read Write) file systems.
When i went into Sdcard 2 no such option. When i went to Sdcard there was. When i went back and held down on SDcard 2 and went to permission that is where i got the error.
Did you format the micro sd card correctly? I had some problems and then formatted it on my PC to FAT32 (make sure you back up your files on the card beforehand to your PC) and all was ok. I can transfer files to it via es file explorer or Astro.
vcs11 - your computer won't show your micro sd (sdcard2), only the internal storage. Disappearing files on sdcard2 seems to be pretty common. For a solution search the forum for ".nomedia" file.
just put some files on the sd card and put it in the sony tablet is there any way of reading the files and installing onto the device without transferring them to the internal drive
i know that ics update will allow this
thanks

Even on Honeycomb, installing any third-party File Manager (I recommend Solid File Explorer or Astro Explorer) will allow you to access those files. The external SD card is located at /mnt/sdcard2 (rather than the conventional /mnt/external_sd or similar)
That problem is indeed solved, but there's another new one: you only can access the SD card in r/w mode with the file transfer app. The /mnt/sdcard2 directory seems mounted in a read-only mode for the rest of file browsers.
When we can access as a root user in ICS we'll be able to remount it as a r/w file system.

That's not the case for me. I have full R/W access to my SD card in any browser including stock and third-party apps. However, I'm running Honeycomb 3.2.1r2 not ICS, so it's probably different.

Yes, /sdcard and /sdcard2 were not write protected in Honeycomb.
Hello to everyone,
may be you can help me. I tried to port a rom from another device(MT6589) to my phone(MT6589).
So i copied app and framework from other rom to my rom. I checked vold.fstab too. They were same. I flashed my phone and it is working really good.
But i have a problem, the internal and external storage are mounted. But apps are not finding them. Camera app says "please insert a sd card".
I can see my Internal and external SD-Cards with Root Explorer or with MiFile Explorer. I can copy files or delete files.
Under Root -> /mnt/ -> SDCard
I don`t any have any idea anymore. Maybe can someone give me a clue.
Best regards,
Mad
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:
https://www.youtube.com/watch?v=sK2O92kgki0
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.
@ndouchin
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:
http://www.mtkroms.com/2015/02/unpackrepack-bootimg-and-port-kernel.html
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

Hey all,
Has anyone had success using Apps2SD or similar? I have a rooted Z3TC and have been trying to partition and create mount scripts for the microSD card in the app but keep running into an error.
Error:
Mount: mounting /dev/block/mmcblk1p3 on /data/sdext2 failed: No such device
I have posted on the dev forum but wanted to check if anyone in the device specific forum has speciality knowledge. And devs are often worked off their feets!

Solved.
2nd partition needed to be formatted as ext4. Still a whole load of other issues to sort through, but I have a working version. (Will never buy a device with this small internal memory again!!!)

Hello.
I have the App2SDPro app and have not been able to get it to work. Can you explain in more details how you did it? 16GB is always making me delete stuff...but there is no phone that can match this size so I just need to find a way to move apps.
Thanks!
Hi,
I use App2SD since a while due to the ridiculous amount of memory of this device. I have something around 320 applications installed with games, gps/maps... all locally installed.
I don't use the "Link apps to SD card" option but only the "Folder Mount" one.
I barely move everything on the root of the internal SD to a dedicated folder on my external SD card.
The trick is to find the folder on which App2SD has the write permissions. As there is a several location for both internal and external storage location it can require some try/fail tests...
I'm on LineageOS and I use these links to move all the obb folder to the external SD card:
Source=/storage/emulated/0/Android/obb
Destination=/storage/NNNN-NNNN/DCIM/App2SD_folders/obb, with NNNN-NNNN the internal SD name
I have unchecked all the options as I normally prefer to move them manually with a file explorer to make some cleanup in the same time.
For some reasons there was some limitation to move directly the Android folder, so do the same for the /Android/Data folder.
Cheers
