UPDATE: Modify vold.fstab file to swap internal/external storage card. Fixed

Interesting concept.. Curious if it would actually work for us.

Would be nice to have my 32GB card as my primary.

So what this does is have everything download and work off of only the external sd card?

Thanks for the files. I'll give then a try.

It doesn't download anything. It does exactly what the thread title and first post say. The external SD card identifies as the internal or /sdcard and the internal SD or phone storage identifies as /sdcard/ext_sd.


Check storage in system settings. Phone storage becomes your external cars, in my case a 32gb card. The internal SD card becomes the external SD removable storage. The main purpose that I did it was to have Google music see my music files on my physical 32gb storage card.

I never said it downloaded anything. What I meant to say is, does this mod makes the SD card the only download path? Basically only having one storage place which will be the external SD card.
But I see you already confirmed it. I will try this.

Hi all,
I have uploaded my file here as i am lost on what needs t be edited in order to have my 16gb external as main or internal on my zopo 200.
Would anyone be kind enough to explain what needs to be edited.
Once i do this, do i need to reinstall ROM and re-root again which i do not mind as the phone is basically new and nothing much installed.
Best wishes
Pete :good:

Hi guys,
same here with my X26i. Same vold.fstab as your, but how to modify to use my 32gb sd card?
Thanks

I think it's in the first post

So this file stored in /system/etc determines what type of storage sdcard and sdcard2 will be identified as. Basically sdcard2 becomes ext_sd.

While most applications are fine with using our phone's internal storage as the primary, google music does not and cannot find any music on my removable SD card. As soon as I copy it to internal it finds it right away. by modding this file, we can essentially have our removable SD card seen as primary storage and the internal secondary or as an external card.

It looks like they sucessfully made this change on the Rezound (http://xdaforums.com/showthread.php?t=1383330 by changing the following:

dev_mount sdcard /mnt/sdcard 37 /devices/platform/msm_sdcc.1/mmc_host/mmc0
dev_mount sdcard2 /mnt/sdcard/ext_sd auto /devices/platform/msm_sdcc.3/mmc_host/mmc2

to this:

dev_mount sdcard2 /mnt/sdcard/ext_sd 37 /devices/platform/msm_sdcc.1/mmc_host/mmc0
dev_mount sdcard /mnt/sdcard auto /devices/platform/msm_sdcc.3/mmc_host/mmc2


I mirrored this change by making ours:

dev_mount sdcard /mnt/sdcard 36 /devices/platform/msm_sdcc.1/mmc_host/mmc0
dev_mount sdcard2 /mnt/sdcard/ext_sd auto /devices/platform/msm_sdcc.3/mmc_host/mmc2

to this:

dev_mount sdcard2 /mnt/sdcard/ext_sd 36 /devices/platform/msm_sdcc.1/mmc_host/mmc0
dev_mount sdcard /mnt/sdcard auto /devices/platform/msm_sdcc.3/mmc_host/mmc2


EDIT: 4/29

Got it working! sorta.. The phone now recognizes the physical storage card as internal phone storage and the internal phone storage as the ext_sd card. Google music finds all music. I have to add a few things to the vold.fstab file to allow a computer to see the actual internal storage card when using the phone in usb storage mode. If you would like to try it, unzip the attached modified.vold.fstab.zip file and push the file to /system/etc via adb after deleting the old one. I have also included the stock one in this post.

KEEP IN MIND: If you wipe internal storage with your phone with this mod in place, you may wipe your SD CARD. Make sure you flash back to the stock file, or just don't use the wipe internal storage feature.

I only change this lines:

dev_mount sdcard /mnt/sdcard auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-sd.1/mmc_host

This worked perfectly, but when I move apps to the internal memory of the phone message said that was not possible because they did not have enough space. 64GB sdcard!

Any idea how to fix it !?

Tks !!

Hello guys,

This is the vold.fstab of my tablet, a P10AN01 with a Vegabean ROM. It have 300mb of internal memory and this ROM takes more or less a half of this. I've searched the two lines to change but.... ...I've missed something or this tablet doesn't have option to swith?

Sorry by my english,

I did that (changed the vold.fstab file) and now I'm on boot loop...when accessing the recovery mode, only adb sideload cmd is available and I can't do nothing.
Any help?
