I had a drive error on my Macbook Pro's 500Gb drive so took the opportunity to clone the drive to a new 1Tb drive so I could max out the drive.

The cloned partition works well but I cannot expand it past the original 500Gb.

I have tried using Disk Utility and when expanding the partition it looks like it completes then it resets the partition size back.

I have tried offline via another Lion startup disk and a USB key and cannot expand the partition either.

Any ideas as to how I can expand the partition past the 500Gb and use the whole drive?

I have run Fix Permissions and the Disk check/repair but this has not helped either.

Any advice would gratefully received!
