Windows reports discrepancy in partition sizes after resizing with gparted

"It turns out that GParted didn't work correctly. I dropped the drive into Windows Vista and pulled up disk manager.

Vista's disk manager showed the partition as taking up the full drive. Uncertain that it would allow me to expand the partition, since it showed all the space was used, I shrank the partition. It allowed me to shrink it by up to 776 Megs, presumably because of the location of various files within the partition.

The result of shrinking the partition was a size of 99 Gb, not 239 Gb. It shrank the partition based on the previous size -- and the size reported by C:\ properties.

I then expanded the partition. The result was correct. Both disk manager and C:\ properties reported the correct partition size of 240 Gb."
