I want to know if I can resize partitions without risking losing any data? My hard drive in spilt into 3 partitions and I run Lion 10.7 on one Snow Leopard 10.6 on another. Below are the partitions and  their sizes.



  • 150GB Snow Leopard HD (100GB free)
  • 300GB Lion HD (150GB free)
  • 300GB Data HD (30GB free)


The list above also shows the partitions in the same way that they're displayed by Disk Utility. I believe DU only allows you expand paritions vertically downwards? I'm thinking of to expanding the non-bootable Data HD partition by around 50GB+ into in the Lion HD partition. (So they appear like the following  they do  below).


    • 150GB Snow Leopard HD
    • 250GB (or less) Lion HD
    • 350GB (or more) Data HD

I do own a copy of Carbon Copy Cloner should this come in useful. All help and replies appreciated
