    I have two partitions on my 120GB harddrive. One is 90.88GB, the other is 20.6GB. They are both HFS+. Leopard is installed on the 90GB partition and the other one is empty. How to I merge these partitions into one 120GB partition without reinstalling Leopard?

    Leopard's Disk Utility has the ability to non-destructively repartition disks. Since your 20gb partition is empty, you could (in Disk Utility) delete that first, then resize the 90gb partition to fill the entire disk.

    As always, backup first! Just in case anything goes wrong.

    Unbelievably easy. I didn't know Disk Utility in Leopard could non-destructively resize partitions. I knew diskutil in Tiger could size them down but sizing them back up was a pain.

    Thanks for the tip. :)
