I tried in fedora 9 to format a partition with FAT32 or NTFS but failed
mkfs -t NTFS /dev/sdb3
mkfs -t FAT32 /dev/sdb3
In both the output says the the device isn't present.
the output is something like this:
mkfs.FAT32: no device present
mkfs.NTFS: no device present
I am able to format in Linux with ext3/4 and so I expected the format type to be visible in the below command output but isn't present in the output
fdisk /dev/sdb
command (m for help): l
I pressed l so as to list the diff. format types
I don't find ext3 or ext4 present. There is a type named 'Extended' but when I run the mkfs command with this type the same error I get. Why so?
ext3 and ext4 are filesystem types, not partition types as shown by fdisk. FAT partition types shown by fdisk exist for mostly historical reasons and have nothing to do with Linux. You likely want to create a Linux of Linux LVM type of partition, and then format it using ext3 or ext4.

While I've never had cause (or wanted to) create an MSDOS filesystem, there is a package you can install to do so:
# yum install dosfstools
...
# ls /sbin/mkfs
[root@test1 ~]# ls /sbin/mkfs.*
