SDcard Filesystem

I (along with other people) find it weird that Asus chose to mount the sdcard to /Removable/MicroSD instead of the traditional /mnt/sdcard.
I would like Titanium Backup to store the files on my sdcard instead of the internal memory, but the problem is that TI only checks the /mnt/sdcard directory. So in my infinite geek knowledge I had the idea to symlink /Removable/MicroSD/TitaniumBackup to /mnt/sdcard/TitaniumBackup. The problem is that FAT32 doesn't support symlinks, so I formatted the sdcard to NTFS and popped it back in but it wouldn't mount it, which I realized was because it doesn't have the NTFS modules. So I popped it back out and formatted it as ext2, but it still wouldn't mount automatically and I couldn't mount it manually because I didn't know what the device name was.
Anyone have any solutions?

You can try ask the developer of TitaniumBackup to include support for asus TF.

Obviously I already did that but I'm looking for a fix on my end.

As with most other tablets, the internal SD is mounted to mnt/sdcard so external SD has to be mounted elsewhere.
As far as TB goes, you can choose where to store backups. Have currently got it setup to backup to Removable/MicroSD/TitaniumBackup
EDIT: If you go into TB preferences menu, scroll down to Backup folder location, then press the Back icon (the system one) to get back to the root folder. Then you can choose the Removable/MicroSD/ folder. Click on "create a new folder", call it what you want, then open that folder. Click the "Use current folder" button and there you go...Backup folder on external SD!
Took me a while to realise that the back icon took you back up the folder tree, rather than closing the folder location window!

It would be nice if we could get a custom mount script or something that would mount the sdcard to something like /mnt/sdcard/music. I'd love to have my music synced to card and everything else stored internally...

Thanks! Thats what I needed to know, I was thinking its kind of stupid that they only have a "detect" button.

What? You're doing it backwards!
If TI is writing to /mnt/sdcard/TitaniumBackup, but you want it to write to /Removable/MicroSD/TitaniumBackup instead, then /mnt/sdcard/TitaniumBackup should be the symlink, pointing to a directory on the SD card!
The target's filesystem doesn't matter (fat32), only the source's (i.e. ext4 on the internal storage).

Good catch, either way it doesn't matter now because I don't need symlinks since I know how to do it in TB now.

[Q] Make external sdcard show up under internal storage

Is there a way to basically create a symlink to /storage/extSdCard on the internal sdcard? I'm using an app that will only let me view files on the internal card. I'm coming from an HTC phone and the external sd card appeared as /sdcard/ext_sd.
I've tried creating the symlink through Root Explorer, Solid Explorer, and manually via adb (with root). I've tried every location I can find for the internal storage (/storage/emulated/legacy, /storage/emulated/0, /sdcard). Every time it says "link failed Operation not permitted".
I'm wondering if there's a way I can basically mount the external sd card in an additional location (in this case under the internal sdcard)? I've used a custom firmware on a router before that had a flash drive mounted as both /opt and /media/USB, so I think it's possible to have a partition mounted in multiple places.
Does anyone know how to do this, or have suggestion for a different way to accomplish it? Thanks.

Would this help you?

Thanks, but I already looked into that. It won't work for this unfortunately.

I use the FolderMount app. https://play.google.com/store/apps/details?id=com.devasque.fmount&hl=en
I use it to create a symlink between the directory in data/data where Google Music stores files and my external SD card.

Thanks, but I've already tried it and it won't work for this situation.

I found the solution, registered just so I can share this with you or anyone who needs it. Folder mount didn't seem to work for me either.
There is a file manager called 'Lidroid File' and a plugin for it called 'Super mount', both are available for free from the play store.
Install them, and then you can nicely pick a folder on the internal storage to mount the whole microSD in it, simple as that!
I needed this for Samba file sharing as I wanted to see the SDcard on the LAN and give it a network drive letter under windows 7.

Any updates to your solution? Does this still work?

[Q] (Blefish 0516) How to forbid app created file/folder in ext-SD root directory ?

Thank Blefish first ,with your contribution to U8800 ,so we users can enjoy the Kitkat.
I have learned that Kitkat will forbid app create file/folder in ext-SD root directory,instead apps can only created their data in /Sdcad/Android.So my Sdcard directory will be tidy.
When I installed Blefish 0516 edition,I found the feature didn't work.
And I found in dir ./storage , ext-SD was mounted as Sdcard0 while the internal storage was mounted as Sdcard1.I think the irregular mounted sequence between ext-Sd and internal storage is the reason why the feature didn't work.
And I didn't found vold.fstab in ./system/etc , so I can't edit it to change the mount seq.
Dear Blefish guru,I am looking for your help~

Jellybean and forward use a different method now. They are not using vold.fstab anymore. Rather, /fstab.qcom is used (in our phone). It cannot be edited manually, a boot.img must be unpacked and repacked in order to do so.
Did you mention that apps can write to /sdcard/ but cannot write to /storage/sdcard0? This ROM does not enforce write permissions as KitKat does by default, so I am not quite sure.

Two days after installed 0516,many folders were created by apps in ext-SD root directory(./storage/sdcard0/),while only two folders were found in internal storage(./storage/sdcard1/).And it seems that the two folders were somthing like being created while using recovery or something like that,unlikely being created by apps.
Cause I am using another rom to find whether the seq between internal and ext-SD is normal,yet I found that in android 4.0.4 there is no ./storage,so I cannot know the seq between internal and ext-SD.

In my ROM external SD (/storage/sdcard0) is the primary storage. This means Android creates it's Pictures, Download, Music & other directories there automatically.
/storage/sdcard1 is just a storage, like USB OTG storage would be. It's not in use if sdcard0 is present (some apps can still write to it manually like Camera).
The /storage is another jb/kk feature. I did not go with the older direct mounting to /mnt/ because it's just deprecated. Mine is configured according to this (Nexus One with internal storage added manually): http://source.android.com/devices/tech/storage/config-example.html

Thanks for so detailed reply.
But I still don't understand how to enforce write permission.As a perfectionist , I really don't want to see so many folders created by third-party apps in my ext-SD.
If it is convenient for you,could you inform me the way to enable the write permission in your rom? :fingers-crossed:

storage/emulated/legacy is empty. Also /sdcard links to storage/emulated/legacy.

Hello all I recently installed XInternalSD from xposed app. Before I did this if I opened Root Explorer and clicked the /sdcard path it would show the files on the internal memory. Now it links to emulated/storage/legacy which is blank and only 900MB in size. Is that correct? I swear it's not.
/storage/emulated/0 shows my internal files just fine, and extSDcard shows the files on my external SD card just fine.
The main reason for this thread is my Titanium backup is failing now because the backup location is set to /storage/emulated/legacy/TitaniumBackup and it says there isnt enough free space. This process worked fine before I installed XInternalSD. I can set it to my external SD card I suppose, but read somewhere that post Android 4.2 it should point to legacy.
I am running CM 10.2.1, Android 4.3.1.
Anyone have any experience or advice?

External SD Card Path

Can anyone tell me the folder path (from ROOT) for the external SD Card? I only ask as I can't seem to locate it in Root Explorer or Titanium Backup. I'm going to be backing it up and don't want to put it on internal storage for obvious reasons.
I looked in:
/mnt (including subfolder /sdcard)
/storage
Both are internal.
I have a feeling that it may not be showing for some reason. TB was pointing to /storage/emulated/0 (internal), but I changed preferences and got it to point to [External Storage]/TitaniumBackup (which is correct). I had to change my "Storage Provider" to "DocumentProvider Storage" in order to enable TB to backup there. Root Explorer still won't allow this.
If I have to do something special to Root Explorer to get it showing, please let me know. Perhaps this is something that changed with Marshmallow?

So strange... but thank you, there is a folder under there with the contents.
