How to create EXT4 and FAT32 NTFS partitions in USB Hard Disk

1) Create two partitions in USB Hard Dsik using 'cfdisk' command.

# cfdisk /dev/sdb <----- Here sdb is the USB drive.

*Suppose we created two partitions /dev/sdb2 and /dev/sdb3 in USB drive.
* Make /dev/sdb2 to FAT32 and Primary.
* Make /dev/sdb3 to EXT4.

Note: We should create one partition as FAT32 and Primary, Other wise we can not open this USB Hard Disk in Windows System.
Note: Windows need one Primary partition.

3)
* Format /dev/sdb2 in FAT32.
#mkfs.vfat -F32 /dev/sdb1

* Quick Format /dev/sdb3 in NTFS.
#mkfs.ntfs -f /dev/sdb3


4)
* Now we can see/open both partitions in Linux System.
* We can see/open FAT32 partition in Windows System.
