Sometimes when I set up a hard drive I get 7 to 8 meg of unallocated space. Other times the whole drive is used. It has never seemed to make any difference - so just wondering if anyone knows why this unallocated bit is there and what is its purpose ? Yesterday I wanted to restore a system image and Shadow Protect complained that there wasn't enough space to restore. I was actually restoring to the same drive I gad imaged but in the meantime had installed Xp as a test. Using Disk Direct 10 I deleted everything and set up a new partition - with no unallocated space, then used SP to restore. Everything seems ok but should there be an unallocated space ?
