I'm trying to do something really REALLY simple: Split up my 92GB HFS+ partition into 3 partitions - a 22GB HFS+, 60GB NTFS, and 10GB NTFS. Why does this fail? This isn't really Bootcamp related, as it blows up in diskutil before Bootcamp even comes into the picture!
Thanks

Disk Utility CANNOT write to NTFS partitions. At all. Period. That includes changing the size of partitions formatted for NTFS. You're stuck. Sorry.

I'm not trying to resize NTFS - rather, to resize the native Apple_HFS partition into a triple-boot scenario, like this: Triple Boot via BootCamp - OnMac.net Wiki, with the only caveat that I don't actually care for the middle partition being bootable (I'm planning to use the middle one as a data disk, rather than Linux system).

You're trying to split a single partition into three partitions where two of them are NTFS. Disk Utility can't do NTFS. Try it with FAT first then convert them to NTFS later in Windows.

You ARE trying to rewrite a partition table that affects NTFS partitions. That means that there is NO way for Disk Utility to do the task because ANY change to the partition table would affect a partition that it can't write to-any change would change at least the relative location of the NTFS partitions, so their entries would need to be rewritten. That's the thing about partitions; they're not easy to mess with to begin with, and they get awfully complicated to deal with when you're talking about multiple file systems.

What you're saying is true but isn't what he's doing. If you look at his Terminal output above, you can see he has a disk with a single HFS+ partition. He is trying to convert it into one HFS+ and two NTFS partitions.

Either way, it's impossible. As you and I have already stated, Disk Utility does not support NTFS. He could do as I said and convert it to one HFS+ and two FAT32 partitions and later convert the FAT32 to NTFS within Windows.

Here's the disk formats that Disk Utility supports

Code:
Valid filesystems: "Case-sensitive HFS+" "Journaled HFS+" "Case-sensitive Journaled HFS+" "HFS+" "HFS" "MS-DOS FAT32" "MS-DOS FAT16" "MS-DOS" "MS-DOS FAT12" "UFS" "Linux" "Swap"

I misread the output-there's a LOT of it! Thanks for the correction.
