It's impossible if the disk is to be used for anything:-)

OK, so an extended partition is also a primary partition. I was just
trying to show that there were no other primary partitions.

Really? Maybe it's me! If I partition a disk, I tend to create the first
three primaries and the fourth as an extended and then put logicals
inside the extended. That seems the logical way to proceed. But as
others have pointed out, Linux works however the partitions are set up.

Which is why I was a little nervous about changing the partition with
fdisk, but as fdisk doesn't touch the file system maybe it is safer in
this case?
