fdisk blank disk chicken and egg problem...

[Andre]

fdisk in Busybox v1.1.0 won't let me create a partition table on a
disk which doesn't already contain one...

e.g.

  pnx0106:# dd if=/dev/zero of=/dev/hda count=1
  1+0 records in
  1+0 records out
  pnx0106:# fdisk /dev/hda

  Disk /dev/hda: 80.0 GB, 80000000000 bytes
  255 heads, 63 sectors/track, 9726 cylinders
  Units = cylinders of 16065 * 512 = 8225280 bytes

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


Even when the disk contains a valid partition table signature it
still doesn't work quite right (fdisk drops back to a prompt without
becoming interactive).

e.g.

  pnx0106:# echo -e '\x55\xAA' | dd bs=1 seek=510 count=2 > /dev/hda
  pnx0106:# fdisk /dev/hda

  Disk /dev/hda: 80.0 GB, 80000000000 bytes
  255 heads, 63 sectors/track, 9726 cylinders
  Units = cylinders of 16065 * 512 = 8225280 bytes

     Device Boot    Start       End    Blocks   Id  System
  pnx0106:#


fdisk in busybox v1.00 works as expected in both cases.
