How to change partition side in XP Pro?

Hi,
I have a XP Pro running. One physical disk, two partitions ( C and D). Both are Dynamic type. As C is running out of space. I try to give some space from D to C, but unable to do it.
In XP Pro - Administrative Tools - Disk Management: all the menus are greyed out;
I install Norton Partition Magic 8.0: Also unable to resize neither C or D.
Q#1: Why I can not resize the dynamic partition?
Q#2: what are the partion types and their significance?
Q#3: How can I resize my C and D drives without reinstalling the whole system?
Thanks a lot.

You can't resize a partition but you can allocate it some unallocated space if you have any. Right click on the partition and select extend partition and then allocate some free space from elsewhere.

There is a detailed explanation of Basic v Dynamic disks at http://support.microsoft.com/kb/314343

Unfortunately you cannot extend a partition unless there is some space to extend it into.

I remember that I was able to use Partition Magic to resize partitions. Maybe the partitions are primary or logical, not dynamic.
If I cannot shrink D partition, then I cannot increase C partion. Any other idea to shuffle space between C and D?
Thanks.

Why Partition Magic cannot resize the partition? Is it because the partition type is dynamic?

Yes. Most disk utilities like Partition Magic can only deal with Basic Disks. I would suggest converting the disks baxk to basic disks but you cant' do this without losing data or backing up the disks first and it would not be possible without great risk on the system drive.

It you want to try - at your oen risk - see http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/dm_revert_disk.mspx?mfr=true

Is it possible to back up system volume? If yes, I might want to try to convert dynamic partition to basic. Say my C partition (dynamic type) is 10 GB, almost full, my D partition (dynamic type) is 60 GB with enough free space for C partition. What steps should I follow to do the following?
1. back up C partition;
2. delete C partition;
3. create C partition (basic type now);
4. resotre system from backup.
I need guidance to avoid running into big problem losing my system. Thanks a lot.

Hi Andrewlee7,
Is it ok to convert system volume on dynamic partition? The article mentions to back up data, not system. So I am a little more cautious before I kill my workstation.

Hi nobus,
The article refers to Windows 2000. As far as you know, is it also ok for Windows XP? As I am converting the dynamic partition which contains my XP system, so I am not sure how to back it safely and completely before I start trying it out. Any advice is appreciated.
Thanks.

I suggest that whatever you do, you backup the important data first.

Playing around with disk settings can be risky.

Once you have done that, you can convert your dynamic volume to basic.

and if you want to be sure, backup your data, and make images of the disks before converting it.(but i never tried making an image of a dynamic disk)
just curious : why did you make them dynamic?

btw - i fyou initialise a disk from disk management in XP, it tries to make it dynamic - i don't know why; but then you can put it back as basic directly even before formatting
