Hard Disk partitioning??

In My RHEL 4.0 System I can see two disk : /dev/sda and /dev/sdb(each of 1199GB size)
I want to make four 200 GB partitions on that hard disk for my required project.
I tried out the following but donno how gonna I make it happen:
node1# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.

The number of cylinders for this disk is set to 145891.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

Command (m for help):

Command (m for help): n

Last cylinder or +size or +sizeM or +sizeK (1-145891, default 145891): +200G

Command (m for help): p

Disk /dev/sdb: 1199.9 GB, 1199997728768 bytes
255 heads, 63 sectors/track, 145891 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1       24316   195318238+  83  Linux

Command (m for help):
Is it the correct way to create 200GB partition further in the same way?

Pls Help

It looks ok but I am not sure if this +200G is supported. I always partition with sizes in MB.
But else everything is fine. You just need to format it using mke2fs.
