Unmounting Hard Drive

[thomashughes]

I am trying to resize my windows partition (NTFS 180 GB, 63% free) down to about 100 GB and make an 80 G partition for XandrOS. I tried using qtparted, but after i set the size and press ok, it comes up with a blank message with an "!" at the top and an ok button.

Then I tried using ntfsresize -s to shrink it. The test run went fine, but when I did it for real, it told me the drive was mounted. When I tried to umount it, it told me "cannot unmount /dev/sda2: device is busy"

How can i unmount it? I thought knoppix didnt touch the hard drive?

You could try http://gparted.sourceforge.net/livecd.php which is 30MB LiveCD for easy partition-editing.
