Can Disk Utility really expand partitions?

    I've seen a tremendous amount of conflicting information on this, so I'm turing to the experts here:

    I dd'ed my ATV drive to an image(s?) on my HD. I then dd'ed them back onto a 250 (grrr, 320s came out two weeks later...). However, I have a 35 GB Media folder, and every attempt to fix this that I've tried has failed.

    I keep poking about on the 'net, and see tantalizing hints that Disk Utility can do the deed. I seem to recall trying at one point and it didn't work. Dragging the line down into the dead area didn't do anything.

    So what's the story? Can Disk Util expand an existing partition into the empty space? If not, does deleting Media and setting it up again do it? Is there some easy trick to solving this problem that uses only Disk Util?

    What on earth is "dd'ed"?

    Then to answer the OP's question, Disk Utility can resize partitions when the drive has a GUID partition table.

    ... and it does not work for the atv properly.
    It screws up the other partitions.

    This methodology DOES NOT WORK, at least on my machine.

    When I tried the lengthy version, every time I tried to re-create the Media partition, gpt would ruin the partition table and the disk would fail to mount from then on. A couple of people mention something like this in passing, but there's absolutely zero detail.

    So then I tried the Simple Alternative Method, which basically says you dd it off, back on, and then run Factory Restore. This does not work either, it leaves the Media partition at it's original size.

    So here I am.

    I know bootcamp can increase that particular partition. I get the feeling normal disk utility my reformat though.

    Disk Utility will compromise an Apple TV hard drive if you attempt to change partition sizes. I use iPartition for my ATV mods.

    I second Cave Man. Just use ipartition. Yes it's $50, but it is literally dragging a slide bar and hitting GO and will work for the ATV. Or you could bang your head against a wall some more.

    Correct, the instructions on awkwardtv do not work properly on leopard.

    You do not need iPartition. I currently have an app in testing that should do it properly for you.
