fdisk/sfdisk/Disk Management problems + unallocated sectors

Hello all,

I've got Linux and XP on dual-boot both running fine - except
that I only now notice that fdisk reports a huge number of
unallocated sectors when I verify the partition table.

In WinXP 'Disk Management' I see a block of 86MB that's
unallocated at the end of the disk.

When I try to allocate a new partition with fdisk under Linux
I get an error message - 'no free sectors available'.

Under Disk Management in XP, the space marked 'Unallocated'
cannot be formatted or used in any way.

Looking at the fdisk -l output I get the idea that there
is something wrong with the partition table. The disk is
supposed to have 4864 cylinders but there is no cylinder
allocated above 4852.

So, can anybody tell me if this is really the case? If
so, how do I recover my 86MB of space 'beyond the last
cylinder'? I looked at the 'advanced' menu in fdisk and
I think it should be possible to tell the partition
table something about what it's missing.... but how?

Thanks in advance!

.... are you sure this isnt the 'recovery' partition
that is allocated on some boxes, which is used to
reinstall the originally-installed OS?

That wouldn't be good enough.
