fdisk raw file issue

[hamed]

I stopped my VPS and ran the following command to expand it:

dd if=/dev/zero of=vm-100-disk-1.raw bs=512 count=0 seek=209715200

After this, I run "fdisk vm-100-disk-1.raw", but fdisk gives the following error:

You must set cylinders.
You can do this from the extra functions menu.


Command (m for help):

when I enter "n" to partition the system, still fdisk gives the above output and does not allow me to create new partitions.

Could anyone please assist me on this?

Thanks

Hi tom,
I've already checked that link.
The problem is with fdisk (or cfdisk).
even the un-resized disk image gives that error.
As to cfdisk, it gives the following error:

  FATAL ERROR: Cannot get disk size
     Press any key to exit cfdisk
