The SD car that is formatted in windows is mounting but the SD card
formatted in Digital CAMRA is NOT mounting.

#fdisk -lV /dev/tfa0 (both camera & windows are same result)
Disk /dev/tfa0: 448 cylinders, 2 heads, 32 sectors/track
Units = cylinders of 32768 bytes, blocks of 1024 bytes, counting from 0
Device Boot Start End #cyls #blocks Id System
/dev/tfa0p1 * 0+ 449 450- 14371+ 1 FAT12
/dev/tfa0p2 0 - 0 0 0 Empty
/dev/tfa0p3 0 - 0 0 0 Empty
/dev/tfa0p4 0 - 0 0 0 Empty
Warning: partition 1 extends past end of disk

The SD card that is formatted on DIGITAL CAMARA is NOT mounting in
Linux.
It says:
#Mount -t /dev/tfa0 /mnt
FAT: bogus number of reserved sectors
Mount: wrong fs type, bad option, bas superblock on /dev/tfa0,
or too many mounted file systems
So, I tried the sfdisk -lV to know the configuration. However, sfdisk is
a read-only command & it will NOT alter the partition table.
The partition table is NOT corrupted as we are able to mount the SD card
on Windows.

So, point here why it is mounting when I alter the first 512 bytes as
like windows formatted device using dd?
