ntfsclone and ntfsresize

[Preston Smith]

I am using the Gparted live CD v 0.3.3.0 to reduce the size of the ntfs 
partition on my USB external drive from 230GB to 100 GB and then create 
a Linux partition with the remaining unallocated space

Gparted won't do the task and tells me there is a problem and that I 
should should run ntfsclone -rescue, then chkdsk /f /r, reboot twice, 
then run ntfsresize - bad-sectors.

I am a total neophyte at this stuff so I have some questions.

1) Running chkdsk from XP Home finds nothing wrong with the drive so it 
appears that the Linux ntfs utilities are more sensitive then XP's.  Is 
this so?

2) I thought Gparted is based on the Linux-NTFS project and that 
ntfsclone and ntfs resize are an integral part of gparted.  Am I wrong?

3) Is ntfsresize and ntfsresue directly accessable gotr Kubuntu and Ubuntu?

Thanks for the help
