    I'm using Snow Leopard version 10.6.8

    I had a 50GB partition setup with parallels desktop which I wasn't using at all so I deleted it in Disk Utility. Then I tried to resize the remaining partition Macintosh HD to take up the extra space but it gives me the error:

    "Partition Failed - Could not modify partition map because filesystem verification failed"

    Any ideas how to resize it and reclaim that empty space?

    In front of a computer. Any computer.
    Try "Verify Disk" & "Repair Disk" in Disk Util.

    If all else fails, you could do the following:
    1. Create a bootable clone of the existing partition (using CarbonCopyCloner) to an EXTERNAL drive
    2. Boot from the external cloned drive.
    3. Use Disk Utility to completely RE-INITIALIZE your internal drive with one partition (which should now use ALL the available space on the drive)
    4. Re-clone the contents of the external back to the internal drive

    Yes, involves some work (and you need an external drive), but this WILL work.
