Windows 2003 and disk resize

Posted on 2007-12-07
Last Modified: 2013-11-30
I am new here - Hi everyone :)

We have a Windows 2003 on an HP server that are running raid 0-1 on two 36GB disk. There are 2 partitions on the disk, basic, C: and D:

We have bought two new 72GB disk and make a new raid 1 - the plan is that the data on the old partition D: will be moved to the new raid, which afterwards will be renamed to D: so there will not be any problems.

But when the old D: partition is gone I want the free space added to the C: drive.

How do we do that, as we can not just delete the raid and date and start from the beginning. Free solutions is of course best :)

- Delete the unuse partition to create a free space
- Run diskpart command to expand your partition to the free space

Yes - this is also what I was thinking. But I got informed by other persons on the web, that this is not possible to add disk to the C: because it is the OS partition and this can not be extended

Byt the way: About a complete backup of the server before starting this resize. Which software do you recommand as it has to work with raid disk. Ghost or ?

Not right. Sure you can expand your C: to the empty space. We have done it with many successes. You just can't use diskpart with Windows 2000, but you are running 2003 so it's OK. Although it has been done with success, you still want to backup your C: before expand it.

In case you want to use the third party software, you can use Acronis True Image. It's paid. I thought you are more interested in free solution: diskpart.

If your boot disk is basic, you can expand it. If it is dynamic, you have to convert it to basic so you can expand it. Diskpart is only working on basic disk

And as for the link you posted It seems only......
