cfdisk and extended primary option (0x05)

[zillah]

I was trying to use cfdusk to create partition within a hard disk,,,,I could not create extended primary partition, though the tag (label) 0x05 for extended is available.

How can I do that ? Is 05 is for this purpose or for something else ?

[zillah]

Any idea ?

You need to create an extended partition first and then a logical partition within. This excersie is moot unless you are acting as root. Also, manipulating a mounted drive is dangerous.

Please post the output of: parted /dev/designation print

I have already created two primary partitions on a hard disk and I want to create extended primary on this hard disk as well.
How can I do that ?

[nad]

In a terminal window shell, enter the command: parted /dev/your_hard_drive_here print . Please post the output.

I created the partitions on both hard disks by using system commander V9.0 utility,,,,then I used knoppix cfdisk utility to check both hard diks and the output was :

[root@0[knoppix]# parted /dev/hdb print

Note: Since I failed to create extended partition on the above PC, and I am looking to use cfdisk to partition another HD on another PC , therefore I raised my thread here.

Why did I receive the above warning message ?

Any idea or help ?

Which HDD are you having trouble with ???
Any other partitioning tool will not use the same scheme and cause errors
For where NTFS is installed and active, use QTparted

and also post the output of

$ sudo fdisk -l /dev/hda (or hdb, whichever the prob is)

you ARE doing this from a LiveCD....yes ?
If not - boot to LiveCD using Knoppix26 1
then leave off 'sudo' in the commands above - you'll be root already (pretty sure)

OH.....BTW -- if you're trying for a Win95/98 Extended partition, the ID = 0x0F (Partition hda2 below)
$ sudo cfdisk
then select -> Print
then select -> Table
