but which one of them works
i have the impresion that only the line from the vold actually works

No it doesn't. the one line in vold.fstab is only there so when I unmount and remount, it mounts the correct INTERNALl SD to /mnt/external_sd (instead of the default EXTERNAL SD)

Below is what actually does all the majic during boot and relocates the INTERNAL SD to /mnt/external_sd and mounts the EXTERNAL SD to /mnt/sdcard.  The trick here is that the INTERNAL SD always gets mounted to /mnt/sdcard from a script that is located on a read only partition (it cant be written to even when the device is rooted).  So this is a work around that moves the mount to another location and unmounts /mnt/sdcard then finally mounts the EXTERNAT SD to /mnt/sdcard.  It works very well.

## swap internal/external sdcard
sleep 2
mount -o remount,rw /
mkdir -p /data/internal_sd
mount -o bind /mnt/sdcard /data/internal_sd
umount -f /mnt/sdcard
mount -t vfat -o umask=0000 /dev/block/mmcblk0p1 /mnt/sdcard
mount -o bind /data/internal_sd /mnt/external_sd

Ok I have a question I change vold but now cant open storage in settings or the original file explorer now I have root explorer but cant get to sd card where original vold file is to replace f-ed up 1.Can u post exactly how to edit that file please.I have been trying to do this internal to external thing for a week now.Ripping what hair i do have left out lol.Thank you in advance for any help

I will attach mine.

These are the only two lines you need in /system/etc/vold.fstab

dev_mount udisk /mnt/usb_storage auto /devices/platform/?usb20_host/usb

dev_mount sdcard /mnt/external_sd auto /devices/virtual/mtd/mtd9

And then add this to /system/etc/install-recovery.sh (if it's not there then add it)

## swap internal/external sdcard
sleep 2
mount -o remount,rw /
mkdir -p /data/internal_sd
mount -o bind /mnt/sdcard /data/internal_sd
umount -f /mnt/sdcard
mount -t vfat -o umask=0000 /dev/block/mmcblk0p1 /mnt/sdcard
mount -o bind /data/internal_sd /mnt/external_sd

ok, i downloaded the external2internal program

 

i got 1/  which is   /mount/internal

2/ which is    /mount/SdCard

 

but part 3/ which says 'retrieve the external sd device (the mount command give it) it should point to the external folder 4/ update the user configuration with these options 5/ and tap on the button above to swap the internal/external'     I am lost with. i assume i have to enter something in the THE EXT SDCARD DEVICE ACCESS but not sure what.

 

should i also have DEFAULT SGS3 Roms checked, as well as SEND RESCAN  and USE PER DEFAULT

 

sorry if i sound like a noob but i am regarding these tablets

I got it to work without external2internal by adding my own script and altering the /system/etc/vold.fstab.

I atached the script and the moded vold .fstab in a post above (look for the VOLD.zip attachment here). That is all you need.

------

/system/etc/install-recovery.sh (if it's not there then add it)

## swap internal/external sdcard
sleep 2
mount -o remount,rw /
mkdir -p /data/internal_sd
mount -o bind /mnt/sdcard /data/internal_sd
umount -f /mnt/sdcard
mount -t vfat -o umask=0000 /dev/block/mmcblk0p1 /mnt/sdcard
mount -o bind /data/internal_sd /mnt/external_sd
##

Add this line to /system/etc/vold.fstab

dev_mount sdcard /mnt/external_sd auto /devices/virtual/mtd/mtd9

And comment out the old dev_mount sdcard line

AND REBOOT

ok, i downloaded your file. where do i place it?

 

incidently, does anyone know why it didnt recognise my 16gb card? i have had to install my 8gb card which it recognised

 

should my tablet be rooted before i do this? or should i have a custom rom? if so can anyone please point me in the right direction

 

 

It does need to be rooted, if you install the custom rom using "ARCTOOLS" from the app store then it will be rooted and will have Google Play installed, and use a rooted file explorer like GHOST COMMANDER or X-PLORE from google play.  Both files in the zip files go to /system/etc but it is better to edit the files and not overwrite them.  If install-recovery.sh doesn't exist then just copy mine to /system/etc.

The 16GB, have you tried formating it.  or maybe it is bad.  I am using a 32GB class 4 micro sd card just fine.
