Disk /dev/sdb: 21.4 GB, 21474836480 bytes

Disk /dev/sdb doesn't contain a valid partition table

[root@ghost ~]# 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 2610.

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)

p

Partition number (1-4): 1

First cylinder (1-2610, default 1): 

Using default value 1

Last cylinder or +size or +sizeM or +sizeK (1-2610, default 2610): 

Using default value 2610

Command (m for help): w

The partition table has been altered!

Calling ioctl() to re-read partition table.
