I use the following command to create a disk image

dd if=/dev/zero of=/tmp/image.ext2 bs=1k count=100000

This is the odd observation, the output of fdisk -l image.ext2 this instruction on my Ubuntu virtual machine outputs

Disk image.ext2: 0 MB, 0 bytes
255 heads, 63 sectors/track, 0 cylinders
Units = cylinders of 16065 *512  = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

When I take the same image to another Ubuntu Linux machine (not a VM) the output is as follows:

Disk image.ext2: 102 MB, 102400000 bytes
255 heads, 63 sectors/track, 12 cylinders, total 200000 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

What could be wrong with my machine?
