Vista - expanding D drive

So I was able to shrink my C: a bit, and I wanted to expand my D: with the
newly unallocated space. But, it won't let me, I think b/c the unallocated
space from C: is not a logical drive like D: is. How can I do this?

Also, if I turn off page files to shrink C:, how much free space should I
leave to turn them back on again? And, are there any ramifications to doing
this?

Thanks!

Once the space is unallocated, it is not a drive and it's source should be
irrelevant since it is now simply empty space on the drive. I don't use this
tool but Disk Management Help, gave the following information:

"For logical drives, boot, or system volumes, you can extend the volume
only into contiguous space and only if the disk can be upgraded to a dynamic
disk. For other volumes, you can extend the volume into noncontiguous space,
but you will be prompted to convert the disk to dynamic."

This would appear to be a limitation of this tool over commercial 3rd party
tools such as Acronis True Image 10 which can resize volumes without
converting them into dynamic (spanned) volumes. I suspect, the volume must
first be converted to a dynamic volume before you expand it or for some
reason it can't be converted. Since I don't use this tool, I don't know if
one process is included in the other.

As to your second question, I wouldn't turn off the pagefile completely.
What I would do is manually set it to a size that would be acceptable to you
in that volume (as I recall, 1.5 times physical memory is the recommended
size), resize the volume, then, depending on your needs and desires, let
Windows manage the size in the new volume since it will do so based on need
and the amount of physical memory you have as well as available free space.

NOTE: since this is temporary, you could resize the pagefile smaller bit I
don't know from your question above, what size you wish to make the volume,
it's current size and the current size of the pagefile. The recommendation
is more or less a guide for what you should allow in the new volume.
