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.

  • Have you installed Total Commander? If so it might tell you something about the mount point.

  • Have you checked the filesystem format on the sd-card? The Galaxy S only supports fat32 formatted sd-cards. It might help to insert the card into a PC and format it manually to fat32

Start by reading:

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 ..
