Cannot resize partition Mac OSX Lion drive after cloning
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!

Not being a MAC guy, I don't know about this, but on m$ Systems there are sometimes similar issues if you expand to use the entire drive, and when you leave a small amount untouched it works. Maybe it is similar with Lion. Have you tried expanding the disk so that there is still some small untouched space left (on windows I usually leave about 10MB...)?

Yup, know about the MS issue - am a PC guy normally so this Mac is a challenge - Partition Magic or EASEUS Partition Manager would have done this in a heartbeat!!!
If you partition to the full terrabyte using Disk Utility, then clone with CCC, it will not change the partition size.

I have done this many, many times when I upgraded drives. CCC will clone from the boot drive while booted. (Good idea to boot in safe mode, though, and don't open any files or apps.)
