    Is there any way to resize your two partitions when one is mac and the other is fat32? I made my fat32 a little too small as it turns out, and would really like to enlarge it a bit.

    Bump...This is no good if there is no way. I cannot do complete reinstall of Windows -- I got ton of apps for work (as in my employment) that would be nightmare to reinstall/reconfigure.

    Noone knows?

    There's a recently added option to diskutil in Terminal that allows you do nondestructive partition resizing. I read an article in a recent MacWorld magazine about this, and there are some websites out there detailing how to do this, e.g. from Google:

    I would personally be very reluctant to do this on my own Mac, even though I'm comfortable with doing similar stuff with gparted on my work machine. If you decide to do this, you should back up everything first.

    Speaking practically, there's no way to do this. While it's surely possible that such software exists to resize partitions, it's probably very complicated, and I myself wouldn't try it on my own personal data. An error could mean the destruction of whatever is on the drive.

    The easiest way to accomplish what you're trying to do is to copy the contents of your drive to a separate drive (or DVDs or something). Reformat the first drive and change the sizes of the partitions. Then copy your data back over. Not difficult at all, and fail safe, assuming you have something with enough space to copy your data over to. If not, you might be stuck with the partition sizes you've got.

    Cheers :)

    Back in my days of being a software developer I used to dual boot Linux and Windows. PartitionMagic would work brilliantly and without fail in situations when I was a little afraid to use the standard DOS util. It really did seem like magic at the time! So, I know this sort of thing can be done well and reliably. However, the PartitionMagic page makes no mention of use with Mac partitions.

    The option of using diskutil resizeVolume from the command line is not good in your case, since diskutil can only non-destructively resize HFS+ partitions. As far as I understood from your post you want to resize both your HFS+ partition and your FAT32 parition. This will not work with diskutil. I don't know about PartitionMagic, but I'd rather guess it will destroy your Mac partitioning.
