Hi all

My C: drive is 1Tb in size (931.43Gb), with Used Space of 73.8Gb and
Free Space of 857.65Gb.

I want to shrink the C: partition down to 200Gb, and use this just for
my OS and App files - I'm running Vista Ultimate 64 bit. This would then
leave me with a new partition of c. 750Gb for my data files and
documents etc.

However, Vista will only offer to shrink the C: partition by around
260Gb as a maximum. It will not allow me to select a larger size than
this. I've tried turning off System Restore / Shadow Copies, but this
makes no difference. Any ideas why this should be, and what can I do?

p.s. I've tried using Acronis Disk Director as well, but whilst I can
select a new C: partition size of 200Gb, when the system reboots,
nothing has changed, so ADD won't work either.

Any advice would be greatly appreciated. Thanks.

Try defragging the hard drive.

The Vista tool will only shrink the partition until it comes up against
an un-movable file. Then it stops.

You could try using Gparted utility on a Linux Live CD....

I would strongly advise against uing GParted and similar utilities
unless you REALLY know what you're doing.
You need to:
1) Disable hibernation through command prompt. Type in elevated prompt:
powercfg -h off
2) Disable system resto Start Menu, rightclick on My Computer, click
system protection in left-hand list, uncheck the drive you want to
disable it on, and confirm your choice.
3) Disable the pagefile: Open up System in Control Panel, then Advanced
System Settings \ Advanced \ Performance \ Advanced \ Change \ No Paging
File.
4) Disable the kernel memory dump. Open up System in Control Panel,
then Advanced System Settings \ Advanced \ Startup and Recovery \
Settings \ System Failure \ change drop-down menu to (none).
5) Run the disk cleanup wizard and be sure to delete all previous
restore points and hibernation files.
6) Reboot
7) Download the 30-day free trial of PerfectDisk 10 Professional.
8) In the PD10 interface, select you drive and run a SMARTPlacement
defrag
9) When that is done, do a consolidate free space defrag. This will
create the largest chunks of fre space as possible.
10) When that is finished, in the main page of PD10, right next to the
size of your hard drive, check the box that says "boot." This will
defrag Windows system files that can only be moved when Windows is not
yet booted. This will make it defrag system files EVERY time you boot,
so you should probably turn it off after the first use.

Using these 10 steps, I went from 3GB available for a partition to over
104GB. After you have done all the partitions you wish, you should
probably re-enable system restore, hibernation, page filing, and kernel
memory dump. I now have a 200GB Vista x64 Home Premium partition (main),
a 25GB partition for testing Windows 7, and a 10GB recovery partition.
Cheers!
