Questions from Microsoft forum

Question1: After upgraded from 2003 to 2008 Server, my drive C was 20 GB which is dynamic disk. My C drive is now almost full. I have plenty of space on other drives. I have not been able to find a tool to allow me to shrink one of the other drives and extend my C.

Question2: I have a Windows 2008 Server with a 500GB disk divided in two partition disk C 50GB and E 450GB both dynamic disks. I would like to expand C to 100GB and shrink E to 400GB, with Disk Management I can shrink E but in order to expand C I need to move the E partition to the end of drive. Already tried with GParted but it can't manage dynamic disk, is there another free software or I have to buy something?

What’s your question?

Have you encountered the same or similar questions above? Do you fail to increase or adjust the dynamic disk system volume with built-in Disk Management in Windows 2008? If so, you can find the solution in this article.

The Disk Management only enables you to extend system volume on dynamic disk under certain conditions, for example, there must be some unallocated space behind the system volume. If not, you must generate some unallocated space by deleting the volume behind the system volume with AOMEI Partition Assistant Server. This software offers a professional dynamic disk manager tool.
