I've put a Chromium OS image onto a USB stick. It takes up 2GB of the 4GB available. I want to allocate the rest of the 4GB to a FAT partition for general storage. The machine I'm using is a Mac (running OS X 10.4) and when I try to use Disk Utility to create a new partition it says it'll wipe the other 2 that are already on there. Is there a way I can make this new partition in OS X without wiping the others? If I were doing it under Linux, I'd use cfdisk or similar and it wouldn't wipe existing partitions...


I'm not aware of a free solution on OSX, but iPartition should be able to do it for a small fee ($45 US).

  • Paying for software? Whatever next! But yeah, it would be an option if I were doing this a lot rather than just once off and then only for fun... – x3ja Jul 12 '10 at 1:30

    Fair enough. Good luck finding a solution, and be sure to let us know when you do! – e.James Jul 12 '10 at 3:30

Try GParted running from a live CD; tutorial here. Needless to say, back up your data first.

  • Yeah, I could just boot into Chromium and do that anyway - I was wondering if there was a non-destructive way of doing it from within Mac OS... as much out of curiosity as anything else. – x3ja Jul 12 '10 at 1:29
  • What I meant to say is I think GParted can resize non-destructively. – JRobert Jul 12 '10 at 15:42
  • I don't need to resize anything though, just create a new partition. I did it in Linux in the end, although for some reason I still can't view the new partition in Windows or Mac... it's "inactive" apparently, whatever that means. – x3ja Jul 27 '10 at 2:29
