Hi all. I am upgrading my Macbook drive from 80Gb - 320Gb tomorrow, and in preparation for this I am going to create a DMG of my Macbook drive, by connecting the Macbook to my eMac, whilst the Macbook is in Target Disk mode.
What I want to know is:
### Will Disk Utility write ALL the empty space to the DMG, or just the data?
I cannot be sitting around for 6-7 hours whilst the WHOLE 80Gb of my Macbook drive is backed up to DMG; surely it will only backup the space that has data on it, and ignore the empty space?.
Please let me know, thanks.
