fdisk fails to create partition, but drive has free space
I'm totally lost and don't even know how to proceed. Below is output from fdisk when I try to create a new partition.

(I should mention that this box is hosted elsewhere, so I have to make sure whatever I do doesn't crash the box...)

OK: Start up fdisk, and look at the partition list. 80 gig hard drive, only about 12 gig partitioned out.

# fdisk /dev/hda

The number of cylinders for this disk is set to 155061.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
  (e.g., DOS FDISK, OS/2 FDISK)

Command (m for help): p

Disk /dev/hda: 80.0 GB, 80026361856 bytes

Try to add a partition, error on no free sectors... WTF?

Command (m for help): n
No free sectors available

Thanks all for any help you can lend!!!

The extended partition (in which you presumably want to create a new logical partition) only extends to cylinder 23985, all of which is already used. In other words, there is nowhere to create a new partition without first modifying the extended partition.

How safely/reliably can the extended partition be modified? Can you recommend an app for doing so?

I don't know who installed this thing, but come to think of it I've never seen an extended partition like that in Linux before...
