[rsaito@flex scsi]$ fdisk /dev/sdf
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.
- Message above means partition did not exist yet, so we can continue
The number of cylinders for this disk is set to 121601.
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)
- n = create new partion, and we chose p = primary, no. 1
Command (m for help): n

d delete a partition
l list known partition types
m print this menu
n add a new partition
o create a new empty DOS partition table
p print the partition table
q quit without saving changes
s create a new empty Sun disklabel
t change a partition's system id
u change display/entry units
v verify the partition table
w write table to disk and exit
x extra functionality (experts only)

**Partition format [#fe33ed86]
- "mke2fs" and "-j" option for ext3
[rsaito@flex scsi]$ mke2fs -j /dev/sdf

/dev/sdf is entire device, not just one partition!
