This happened to me, too. I first noticed it after upgrading, recently,
to Ubuntu 10.04 from 9.10. I decided I wanted to go from dual-boot (with
WinVista) to single-boot (Ubuntu 10.04 only). I opened GParted, and it
showed my disk, /dev/sda, as wholly "Unallocated Space." Same thing when
I tried booting from a GParted Live CD and from an Ubuntu 10.10 Live CD.
I have not lost any data, but it is very frustrating. Below is the
output of 'sudo fdisk -l /dev/sda':
Disk /dev/sda: 120.0 GB, 120034123776 bytes

I'm not expert, but that partition table looks a little odd to me. Any
help?
