Swap back to internal memory

[alexyug]

Hi everyone!
I've installed CM10 (4.1.2) from SD card. Now I want use device without SD card. But applications don't work without external SD card (No external storage available). I suppose this is because CM swapped internal storage with the SD card.
Now I want swap it back.
I've found vold.fstab file located in /system/etc folder. It contains:
dev_mount sdcard /storage/sdcard0 auto /devices/platform/msm_sdcc.3/mmc_host/mmc1

Please help.

Best regards,
Alex
