Bug Description

On a Windows 7 laptop (Acer Aspire 6920G) running Windows 7 64-bit, I had deleted a bunch of data from within Windows, then rebooted to install a dual-boot with the Kubuntu Raring Beta 1. However, the option to auto-resize was missing, and the installer appeared to believe that the main partition was 93% full, which sounds about what it was before I cleaned it up from within Windows.

Windows and GParted, by contrast, peg the free space at ~60%.

In Windows, Disk Management appears to show the disk as being "Basic", presumably meaning it *isn't* under the purview of the Logical Disk Manager. A screenshot of this can be seen at http://keithzg.ca/images/utility/acer_diskmgmtmsc.png or as the attachment (not sure which is better; apologies, first time actually opening a bug!).
