Any system that has EVER had a file system with Windows or DOS on it has the

Part #s 1-4 can be primary.
Part #5 is always an extended part table to hold logical drives.
Parts 6 and up can be logicals.

it really seems like we can't agree on terminology or ???

parts #5-#11 are included in #4

And Windows allows for 4 primaries, not 3. So a mixed system or a migrators system will have a mess.

You are using SCSI, me IDE also.

where anything based on DOS or Windows sticks the extended is based on how many Primaries there are:

What fdisk saw on theHD after diskdrake was done as I described was:
hda1 /
hda4 Extended
hda5 /cookermirror (type unknown)
as in /etc/fstab
but hda5 was unformatted and marked as Ext2 when I told Diskdrake to use Ext3

here is the /etc/fstab

[root@ root]# cat /etc/fstab
/dev/hdb1 / ext3 defaults 1 1
# /dev/hda5 /Cookermirror ext3 noauto 1 2
none /dev/pts devpts mode=0620 0 0

/dev/hdb6 /usr ext3 defaults 1 2
/dev/hdb5 /var ext3 defaults 1 2
/dev/hdb2 swap swap defaults 0 0

The commented line is what I had to pull to get the machine to boot past an ext2 fsck that said it could not find a superblock when I tried to boot the machine into Linux.

BTW, Supermount WORKS on this P4 box, even in stock Mandrake 9.0.

I was trying to use Diskdrake from the GUI when this happened, as any newbie would.
