    Hi All

    I have a 500mb hard disk - which is partitioned into 200mb and 300mb.

    The 200 is my primary start-up partition - running Lion. It has 28mb left free.

    The 300 is my secondary partition...and has SnowLeopard installed. It has 168mb free.

    I want to increase my 200mb partition to 268mb - by taking free space from my 300mb partition.

    How can I do this? I have tried Disk Utility - but no luck :(

    Cheers

    :)

    Open disk utility. Select the 500GB hard drive. Click the partition tab. Drag the partition size to increase the smaller drive.

    I'm not sure you can do this though while your operating system is running. If it doesn't work, boot from your install disk and run disk utility from there.
