friends,, I have change my mind a little,,
I want to gave the remaining capacity above then 500gb of G: to E: which is 70gb capacity.. wo how I do that,? shrink G: drive is best or break all Logical drive..?
If I shrink G: then re-allocate the unallocated capacity to E: then E: is still accessible or require format,? because I put some data to E:

Backup your DATA.
You will need to format new Partitions.

shit shit shit,,,
I resize/move 570gb G: drive, then the unallocated 70gb merged to 100gb E: drive,, then PW require restart the PC.
after restart, pw boot wizard is start, after that, pc restart again, and then I see that nothing any thing changed, G: is still 570gb and also E: is 100gb.
then I delete all partition and create again but one thing I really dont like it.. when finish creating all partition, in the last 9mb unallocated is remaining.. but in the previous partition, its not shown..its not a problem, but I m very discomfort to this...

(1) You can always simply CHANGE DRIVE LETTERS on any partition. It doesn't matter what the drive letters currently are, you can change them.

And drive letters for partitions do not have to be consecutive, corresponding to physically consecutive partitions. They can be lettered anything you want them... using any letters of the alphabet.

(2) To re-size G to make it smaller, and give all of its returned space to E, why not just rename the partitions... call E -> G and call G -> E. You will need to use one intermediate step to accomplish that, say E -> X, then G -> E, and then X -> G.

Now you've got the drives "reversed" with E as the 570GB drive at the high-end of the drive, and G down lower. But what do you care? They're just drive letters???


Now I'll read your later post, to see what you actually did so far.

As far as that leftover 10MB of "unallocated", yes... I understand you'd like to absorb that if possible into your G partition so that it doesn't appear.

If you try to "re-size" G using Partition Wizard, does it now allow you to reduce the unallocated space after the existing partition from what I would guess is that 10MB to zero? Is there currently 0 shown "after" the G partition in the re-size dialog? Or is it 10MB?


Anyway, there is a certain fixed overhead in the setup of the "extended partition" inside of which all of the "logical" partitions are sub-defined. This is usually 7-10MB, and cannot be avoided. But it usually is physically located at the FRONT (left side) of the "extended partition", and would normally never appear as "unallocated" because it really cannot be allocated to a real partition. It is simply fixed overhead for the "extended partition".

So I wouldn't think this 10MB at the upper-end of the drive is this fixed overhead for the "extended partition".

And yet, it shows up. Maybe it's just a "rounding error" on the allocation of partitions, and the total size of the "extended partition" covering all of your "logical" partitions.

Anyway, if you can re-size your G partition, and that 10MB appears available above the partition, which you can then reduce to 0 (thus enlarging G to include this final 10MB), then fine. If not, well, I suspect it's just "rounding error" and you're going to have to live with it, unless you want to delete all of the "logical" partitions and start over allocating them from the once again single consolidated 901GB with no dangling 10MB showing.

Just make sure that as you allocate partitions (maybe in reverse order, starting from the high-end of the drive and working downward, and then manually re-lettering them if necessary so that you get the drive letters you want for each partition) you ensure that there is 0GB after.


Anyway, presumably you have your initial data on some backup medium, since you loaded your partitions initially after partitioning the new drive from scratch. So I assume in worst case you could do that again, deleting all partitions D-G and starting from scratch... this time to your new specifications. And then you'd re-copy your starting data to the correct partitions.

But after the fact, if manually re-lettering two drives (to accomplish a "letter reversal", which is an easy way to re-size without actually re-sizing) doesn't give you what you want, you'll simply have to accomplish what you want in multiple logical steps:
(a) re-size the key partition, and then

(b) MOVE adjacent partitions right or left into the now unallocated space from the first re-size, and then

(c) enlarge the partition you really wanted to enlarge.
All of this should not require a re-boot, since it doesn't involve C.

Alternatively, as I suggested earlier, maybe just reversing drive letters would accomplish what you want in the easiest way. Again, the drive letters assigned to partitions are 100% under your control (except for C, which cannot change). And they do NOT have to be consecutive... they can be anything, anywhere.

in PW, the resize/moved operation is not done with me.. I mean I can't do the resize method in pw. so that, I delete all partition instead of C:, then re create them all with new changes of space, only one thing is discomfort to me the last 9mb unallocated is remain, because it is not show previously,,,
anyway,, as you said, it should be some rounding error, or something,,,
and now, the partition condition is lock like that,, I think its ok ,,,,

Your original arrangement was:
C - 29.90GB
D - 30.00GB
E - 100.58GB
F - 200.19GB
G - 570.74GB
Your rearrangement goal was to enlarge E by 70GB, thus increasing its size to approximately 170GB. And the plan was to find the 70GB you needed to enlarge E, by taking 70GB from G (keeping its right edge just where it is, and moving its left edge to the right by 70Gb) thus reducing G down to approximately 500GB. And obviously in order to make that happen, you would have to keep the F partition in the middle between the increased E and the reduced G exactly the same size of 200GB but slide F to the right by 70GB. That was the obvious plan, and the steps that would be needed.

Looking at the original partition sizes, I believe you should have approached this task with the following sequence of steps using Partition Wizard, in the exact sequence shown:


(1) RESIZE G to reduce its size by 70GB, sliding its left edge to the right by 70GB. The right edge remains where it is (i.e. at the upper end of the drive), and the left edge moves to the right by 70GB.

You accomplish this by specifying the unallocated space on the right of G to 0GB, and the unallocated space on the left of G to 70GB.

In the graphical representation of the drive, this would then show 70GB "unallocated" to the left of G, located between the right edge of the current F and the left edge of the resized G.


(2) MOVE F to the right by 70GB, thus taking up all of the "unallocated" space to its right move, and creating a new "unallocated" area of 70GB to its left, located between the current E and the moved F.

You accomplish this by specifying the unallocated space on the right of F to 0GB, and the unallocated space on the left of F to 70GB.

In the graphical representation of the drive, this would then show 70GB "unallocated" to the left of F, located between right edge of the current E and the left edge of the moved F.


(3) RESIZE E to increase its size by 70GB, absorbing the 70GB unallocated space now to its right, between its right edge and the left edge of the moved F.

You accomplish this by specifying the unallocated space on the right of E to 0GB, and the unallocated space on the left of E to 0GB.

In the graphical representation of the drive, there should now be NO unallocated space between any of the partitions. E should now be approximately 170GB, F should be approximately 200GB, and G should be approximately 500GB.


You can either use the graphical sliders to move the left and right edges of the partition you're working on, or you can manually type in the numeric size values in the numeric entry area, or you can use the up/down arrows to "spin" the numbers until you get the value you want to see.

Once you get it all set up and the graphical drive representation of the partitions looks correct, you push the APPLY button and the queued operations will be performed in the above sequence, accomplishing the resize-G/move-F/resize-E you want to accomplish.

And then you'd end up with your goal:
C - 29.90GB
D - 30.00GB
E - 170.00GB
F - 200.00GB
G - 501.50GB
I honestly don't know why you somehow got that 10.34MB unallocated at the end, and I do understand why this is bothersome. But I suspect if you'd done things in the three steps I defined above, which uses up 100% of whatever you shrink from G to slide F to the right, and then to enlarge E... I would have expected to not have this 10.34MB mysterious space.

But, maybe it's just some kind of a "rounding error" resulting from partition boundaries, that cannot be overcome.

Anyway, your current screenshot looks just fine. I really do believe that if you'd followed my three steps above, in that sequence, that you should have had no problem whatsoever with Partition Wizard doing exactly those actions.

wow,, this is the real method to do that, moving 70gb unallocated right to the 100gb E:.
but previously, it cannot done by me because I was doing a mistake,, I do not move the 70gb shrunk unallocated from G: to the right of E:,
I just shrink 70gb from G: and then right click on it and wanted to click "Merge" (I though merge is the way to 70gb merge in E
but the merge option not available until I click create the 70gb partition,
when I create 70gb another 6th partition, then Merge option is appear on its right click menu, then I right click it, click Merge and Merge it to E:. and then click apply, it says me to restart computer, after restart, pw boot wizard starts, and its merging operation takes 4 steps,,
and after the boot operation of pw, when starts the pc, then nothing anything happen, I mean merging option did not work, and partition is still the same,,
that is the mistake I was doing before,,
anyway, I delete all partition and re create again with new spaces of drive,,, and it worked, jst discomfort wth 9mb unallocated,
anyway,, its ok,, now I m using hard drive, and transfer my old hdd data to it,,,
thank you very much for very useful information..

You can't magically make the newly unallocated 70GB that is manufactured by reducing G fly into E.

You have to do this in three logical steps, as I detailed above:

(1) reduce G by 70GB, creating 70GB of unallocated space to its left
(2) slide F to the right by 70GB, absorbing the newly available 70GB now to its right, and producing a new 70GB of unallocated space now to its left
(3) enlarge E, absorbing the new 70GB of unallocated space now to its right.

No partition "merges", no new partitions created and then "merge"... just resize G, slide F, and enlarge E.

For the future, now you know how to approach this type of problem. Just think of it graphically, exactly like Partition Wizard presents its picture of the drive and the partitions, and it's really intuitive what steps you need to go through... to make the picture end up looking like you want.

.Yes, you ended up with what you wanted... with this small 9MB unallocated as the price.

Otherwise, nice work. Mission accomplished.
