Mac Geekery

I have a MacBrook Pro (Intel) with Mac OS X and Windows XP. I want to resize Windows from something like 40GB to 100GB. I successfully used (IIRC) “diskutil resizeVolume disk0s2 40GB” to shrink the Mac partition, but now I’m having trouble enlarging NTFS.

When I use ntfsprogs 1.13.1 ntfsresize, it thinks the NTFS has no room to expand (but I think it does!).

vp-bc:/tmp/ntfsprogs-1.13.1 vincepetti$ sudo ./ntfsprogs/ntfsresize /dev/disk0s3
ntfsresize v1.13.1 (libntfs 9:0:0)
Device name        : /dev/disk0s3
NTFS volume version: 3.1
Cluster size       : 4096 bytes
Current volume size: 54750523904 bytes (54751 MB)
Current device size: 54750527488 bytes (54751 MB)
New volume size    : 54750523904 bytes (54751 MB)
Nothing to do: NTFS volume size is already OK.



vp-bc:/tmp/ntfsprogs-1.13.1 vincepetti$ diskutil list
