    I have just recently deleted my Bootcamp partition in Disk Utilities, and now im trying to increase the partition size of my Macintosh HD drive.

    When i go to the partition map and try to increase the size.
    The same error always appears.

    "Could not modify partition map because filesystem verification failed"

    I have attached an Image of what my partition map looks like right now.

    Please can some one help me.

    Put in a OS X install disc such as Snow Leopard or Leopard (Doesn't have to be the OS you're running), boot into it by holding option after you restart, run disk utility from there and click repair disc.

    I know the problem.



    You need to manually open bootcamp and correctly uninstall the windows 7 partition. Simply deleting it from your partition leaves data on your HD.

    I had the same problem, and now I have another. I can't create a third partition to attempt to run a copy of the Lion Beta. It's giving me the filesystem verification error.

    I deleted the partition through disk utility initially, so don't worry if you think its to late. Let me know if this worked for you.

    If anyone knows a solution hit me up at Regiment47@aol.com

    This.
    I had all my data on the second of two partitions on my HD and this is how I was able to delete the partition HD1.
