fdisk problems.

I am trying to wipe out a Compaq HD the has a Primary DOS partition and a Extended DOS partition.

I quess Compaq saves info for restore on the extended drive.

I have deleted both partitions gone into "Display partitions" and it says all is gone.

Then I restart go to fdisk, check "Display partitions" and the partitions are there again. I have wiped them out three or 4 times now.

Is there an order I must delete the partitions in? And even if there is, why do they show up again when they say there's no partitions?

Really confused

did you go through a procdure similar to this one? http://www.cybertechhelp.com/html/tutorials/tutorial.php/id/36
what version of fdisk are you running?

Sequence for FDISK:
first delete partitions inside an extended partition.
Then delete the extended partition(s).
Finally delete the primary partition.
