If you just want to format the drive, without recreating your partitions on your hard drive, and you want to format as jfs .....

mkfs.jfs /dev/hdc

If you want to create or delete partitions before doing this.... fdisk /dev/hdc

You'll need to be logged in as root to do any of this.

Good luck

Ok, assuming that the drive is the second drive ( hdb ) and that you are going to use the entire drive for the partition you make, proceed as follows....

type: fdisk /dev/hdb

Command (m for help):n as in new partition

Command action... Select p primary (1-4)

Partition number (1-4):1

First Cylinder (some numbers): press enter

Last Cylinder or size : press enter here also because you are going to use the entire drive. If you want, you could set the size with something like +3000m which makes the partition size of 3 Gigs.

Command (m for help): t as in type of partition

Partition number (1-4): 1

Hex code (type L to list codes): 83 as in linux ext3

Command (m for help): w to write the new information

Now to format the partition, type: mkfs.ext3 /dev/hdb1

You can verify things with the command:fdisk -l

To mount that partition as www in linux...

Type: mkdir /mnt/www

Type: mount /dev/hdb1 /mnt/www

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 232514.
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
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
