General :: Write Only Access To Internal / External SDCard On Kitkat
Jun 2, 2014
I am using a mt6582m device with kitkat 4.4.2 with supersu. I can use root to write to system, data and cache using es file explorer, can also read and write to any sd card, but apps like titanium backup, online android backup, ram expander can't read/write to sd card.
Eg.1: ti backup read backups, can do all operation except backup and restore.
I had read a lot, changing backup path didn't worked nor any odex file is there. Using v6.1.5.6.
Eg. 2: ram expander can create swap file on sd but can read it saying 'not found'. Swap can be used with cache partition.
Eg. 3: online nandroid backup says pat not vaild.
I had tried, sd fix app, manually editing platform.xml, xposed module to 'handel external storage', change permissions using es file explorer, editing ramdisk.
There is storage/sdcard0 and 1
Also mnt/sdcard and mnt/sdcard2 (symlinked)
Also mnt/media_rw/sdcard0 and 1 (not readable even in es file explorer)

i have xperia ray and i want to swap my external sdcard with the internal memory.. Xperia ray has 300mb of internal memory and it's really low and isn't enough.. i know that there's a hack that switches the external sdcard with the internal memory.. i found a thread [URL] ..... that explains how to do that but i don't have the same line that the thread started has..this is what i have:
Code:
# Mounts the first usable partition of the specified device
dev_mount sdcard /mnt/sdcard auto /devices/platform/goldfish_mmc.0
[code]....

I finally upgraded to android, i got the cheapest phone possible(kyocera milano) which seems to be a mistake. The phone has only about 300mb internal storage and can barely handle its own updates(because of the limited storage). so i would like to know if its possible to make the phone "think" that some of the sd card is part of its internal memory? I found an adb driver for it(dont ask me where or which one because i had no idea and started messing with one until it worked) i have not tried rooting but can if i need to.

I'm searching for a solution to swap external sd to internal. I had to break the internal storage to make a I9003 working again.
Now, it boots the ROM from the external (but that's an other story).
Camera needs storage0 (internal storage) to work properly for DCIM. But I have only storage1 (inserted microsd). In 2.3.6 swap sd was possible by editing vold.fstab. In Kitkat the opportunity has been denied.
I search for a way to make storage1 to storage0 in CM11. Whether CyanogenMod is working on it?

I really don't have any desire to root in general...perhaps if it were all simple and zero-risk, OK.
But I'm considering root just to get full, normal, access to microSD. Is root the only way to get access?

I'm running a custom ROM (4.2.2) on an HTC Vivid. When I connect to my PC via usb, Windows only sees the internal storage, not the external sd card, and there's no way to navigate to the System partition to access.
When I was running the stock HTC ICS, Windows would mount the external card as a separate drive. I know the file system hierarchy is different with JB. Is this why it only sees the internal storage now?

Method to allow myself to install apps and games to my external 32gb external sd card and set this as my default install location as my internal storage is small and i always have problems with available space . I have been told this can be done on adb on computer with running special commands to change default install location. Is this true ? Will I need to root and use an app which is user friendly for this? I have a samsung galaxy s4 mini gt i9105 unrooted.

Currently, ICS on my sgs2 shows my external card as mounted with empty contents (in storage settings). Both /mnt/sdcard and /sdcard point to the internal sdcard storage. Where is my external card mounted? GT-I9100

I'm trying out encryption, and have just encrypted the external SD card for now.My goal is to encrypt both the external and internal cards.
But to my surprise, I've noticed that the external card is accessible (I can read its contents) from recovery (CWM) without having to type any password...

I formatted my internal sdcard to exfat by mistake while trying to simply format it(for some reason windows defaulted to exfat instead of fat32) now my sdcard won't mount and I can't format it in windows and can't mount it, I could get it back to fat32 and working again.

I have a tablet with internal SD (nand one) and an external SD.
Now I can read contents in internal SD but can't write it. I checked up with root explorer, finding the file sysytem is "read only". After toggling it to R/W, the storage can be written by root explorer but still can't by other apps.
================ EDIT ================
p.s. When connected to PC as massive storage device, it can be read and written.

I'm on a S4 (I9505) phone and a lot of media files and also nandroid files are disappering from the sdcard (SDXC 64Gb). Yes, deleted. Most probably mounting and unmounting the sdcard, or rebooting, are removing the nandroid and media files.
I've used both TWRP and Phip recoveries. They work only if I unmount the storage card and reboot. Otherwise, in the first reboot, file are gone. Some users here in xda say we need to use short backup names. But it did not work for me.
Maybe it should be solved by the ROM side. But I'm not lucky and not finding a way to get a solution, not even using different kernel versions. Changing the WRITE_EXTERNAL_STORAGE permission suggested in many sites does not solve the issue [URL] ..... New ROMs seems to have incorporated this solution, but the problem is still there.
I also not being able to change the permissions for the mnt folder as suggested elsewhere here in xda. The operation (even my phone rooted with SuperSu) is not successful.
External SDcard is useless if we cannot trust on it.

my internal SDCARD is corrupted and the /data partition is unusable.
My device is i9003 and it's running on MIUI at the moment. By default MIUI didn't detect my external SD or my internal SD but after editing "vold.fstab" I was able to mount the first partition of my external SDCARD as external memory and everything was good, I could finally use the camera and pretty much do everything else.
But I was still unable to mount the second partition of my external SDCARD as my internal memory which meant none of my messages could be saved and the phone would pretty much go back to factory settings after a reboot, this apparently is because the /data partition (present on the internal memory) stores all the user data such as the time, the theme I'm using, etc and not having a /data partition meant none of these settings were really saved.
Having no internal memory also means I cannot install any apps such as Link2SD.
Moving on, after many hours of googling I found out that it might not be possible to mount the internal memory using "vold.fstab" and the only way to do it could be by mounting the memory manually during init.
I want to use the second partition of my external SDCARD as internal memory, this is likely to solve all my problems and make my phone usable again.

I followed this simple steps [URL] ..... and installed cyanogen mod on my samsung vibrant.
The problem i am facing is that its not detecting my internal 14GB memory.
When i go into clockwork recovery mod, there i am able to mount my memory and its visible in my pc.
How to make it usable in phone?
I tried with different cyanogenmod rom's nothing make the sdcard (internal memory) detect after phone starts.
One thing is its not cracked, because i am able to access it from recovery when i mount the usb storage using clockworkmod, it displays the contents in computer.
Also I was thinking if can i use external SD card to save my camera pictures ? It does not have camera menu options as storage location.

I am under ICS 4.03 on Acer Gallant Duo (E350) (MT6575)
/sdcard = internal storage
/sdcard2 = removable storage
I change build.prop parameter to ersist.sys.usb.config=mass_storage,adb
My device switched fro MTD to UMS correctly but only internal sdcard in visible and mount on my computer.
/sdcard2 (external sdcard) is not visible and not mounted on computer.
The strange part of the process is that /sdcard2 is unmount from the device (ACER) but not presented to the computer.
I tried to reformat the external sdcard2 without success.

Since my last upgrade of cynaogenmod nighties yesterday on my galaxy s2, my internal AND external sdcard are not mouting anymore
I tried to understand why and I found that my /storage folder was empty. I think it should have been populated by /init.smdk4210.rc script :
Code:
...
on early-init
export EXTERNAL_STORAGE /storage/sdcard0
export SECONDARY_STORAGE /storage/sdcard1
mkdir /storage 0775 system system[code]...
I would like to retrieve my internal sdcard content.

So I have this GT n7000 with android 4.0.4 ICS, rooted. I want to swap my 32 gb external sd card with my internal one. I googled it, found a method that included replacing a vold.fstab file in system/etc but that was only for jellybean. I need a method for ICS. Also I can't understand what usb storage means. Is it different form internal sd card??

Today android phones are coming with an internal storage which is called the internal sdcard. Because of this the need for external sdcards is vanishing day by day. But when your phone is factory reset you lost all the data stored in it while in case of external sdcard you have an option to save your data. If you accidently lost all the data stored in your phone then don't worry I have a solution to get it back. This trick will work on phones having mass storage mode support, if you are running android 4.1 jellybean and above then root your phone to get mass storage( the tutorial is different for different phones),
If you have accidently lost all your files, photos and videos from your phone then after this do not copy new files to the phone. This also include clicking photos and capturing videos. If you copy new files to the phone then you are actually reducing your chances to get back your deleted photos and videos and other files. In short just don't download anything to your phone, do not use the internet on your phone till the time when you get back your lost files back.
This trick will only work on android phones having mass storage mode and MTP (Media Transfer Protocol) options. If your device is rooted then you can enable mass storage mode on your android phone. After enabling mass storage mode you can get back deleted photos, videos and all files from the internal storage of any android phone.
Requirements
1. Recuva for Windows 7, Windows 8
2. A USB data cable.
Now Follow The Steps Below
-Download and install recuva. While installation do not uncheck any option.
-Now connect your android phone in mass storage mode. Connect it to pc a notification will appear in the phone, tap it to enable mass storage.
-Now open My computer and you will see Removable disk.
-Open recuva and click Next, on the next step All Files will auto selected. Again click Next. Then choose In a specified location and click Browse.Choose the removable disk or MTP disk here and click Next.
-In next step put a check mark in Enable Deep Scan and click Start.
-After scan is finished you will see the list of all deleted files. Green circles is means that file can be recovered while red circle means unrecoverable file.
-Now check the box next to Filename to select all files. Click Recover on the bottom right and choose Desktop .Your deleted files will be recovered.

so my galaxy s2 has been running on RR 3.0.5 with the latest siyah kernel. A problem I've been having is frequent media corruptions, and to solve that, I thought reformatting the internal storage would work. After doing so, it doesn't recognize my sdcard. What can I do to fix this?

Trying to customize my new device (Runbo X6: MTK6589T, 2GB RAM, 32GB ROM, Android 4.2.1) .
1) Repartitioning
Actually, I successfully edited the partition table in EBR1 and EBR2 and the start addresses in the Scatter file and proofed it multipple times by recalculating, but after flashing, although I get a correct output in system settings and by dumping /proc/emmc, /proc/partitions and /proc/dumchar_info, when I try to push some apps, for ex., above the initial 680MB to /system/app or something similar I get a "disk is full" message. As I was able to find out only the /data and /fat partitions get physically updated by the new sizes, meanwhile the /system and /cache partitions remain physically on the initial state and get updated by the new sizes logical only. Although if after flashing I dump the system image by "cat /dev/block/mmcblk0p5 > /sdcard/system.img" I get an image with a size corresponding to the updated size of the partition.
Initial values:
EBR1
begin /system = 00 18 02 00 (real 00 02 18 00)= 137216 blocks (* 512 bytes + 1024 blocks of 512 bytes) = 70778880 bytes
size /system = 00 50 14 00 (real 00 14 50 00) = 1331200 blocks (* 512 bytes) = 681574400 bytes
begin /cache = 00 68 16 00 = 1468416 blocks = 752353280 bytes
size /cache = 00 F0 03 00 = 258048 blocks = 132120576 bytes
begin /data = 00 58 1A 00 = 1726464 blocks = 884473856 bytes
size /data = 00 00 40 00 = 4194304 blocks = 2147483648 bytes
[Code] ......
I also read somewhere that it is also necessary to edit PMT: in that case I tried to flash with original PMT, edited PMT and without PMT, but cuoldn't notice any difference.
2) Mounting the internal memory and external SDcard on system start natively as EXT4 instead of FAT32
Using my old device (Runbo X5: MTK6577) I had success on mounting the internal storage as EXT4 by disassembling recovery.img and editing /etc/recovery.fstab to change the "vfat" value to "ext4" and reformatting the storage after a successful boot with ne recovery, but on Runbo X6 I get no change to the filesystem after reformatting. By the external SDcard I never had success.
