Why is my 16GB SD card not being read in my Samsung Galaxy S? Why is my 16GB SD card not being read in my Samsung Galaxy S? 

I've tried to format it several times but nothing happens.

xda developers >. [Help] Changing Around Mountpoints for sdcard and extSdCard?


  Excerpt: Some previous Samsung devices had no external storage at all but still mapped the biggest flash partition to /mnt/sdcard.
  The Galaxy Tab 2 7.0 has a Micro SD card slot on it (one of the reasons I bought the thing!), but I guess for compatibility they still mount an internal flash storage partition to /sdcard. The actual micro SD card gets mounted to freaking /mnt/extSdCard.




First you need to find out where it is being mounted (on Galaxy S), and whether the command you are using is for internal flash OR the microSD card ..
