Machine is a laptop running Vista Home Premium I had a large partition that I resized using the Vista utility, from 138GB down to 96GB. That's all the further it would let me reduce it in size even though only about 15GB was actually used, the rest was free space. I wanted to make it even smaller, but Vista wouldn't let me. Question 1) Is that because the Vista utility will only remove unused sectors, but won't take the next step of relocating files to utilize the allocated space more efficiently? Or is there something else I don't understand? Question 2) Since DDS will allow me to shrink the partition down to the size that is actually used, I assume it must relocate the files to compact them into a smaller address space. Is that understanding correct, or is there more to it than that? After reading the user manual I went into the automatic mode and resized the C: partition to make it a little smaller. The new partition size was applied, but the machine wouldn't boot. So I recovered it with an image I had just taken with True Image and it seems to be OK. But the image I had was using the old partition size, which was bigger than the new size. TI was aware of that and showed the before -> after partition sizes during the restore operation. Question 3) As long as the partition size is large enough to support the actual data size used in a disk image, is there any reason you shouldn't try to restore an image to a partition of a different size than when the image was created? TI seemed to take it all in stride, so I assume this is OK to do, but would like confirmation on that. Question 4) From further reading I learned that resizing the OS partition is better served using the Boot Disk, otherwise critical OS files can get trashed in the process. I'm assuming that's what caused my inability to reboot after doing the resizing without using the Boot Disk. Would that seem likely?
