How to resize RAID without losing data

RAID is the common Windows server storage media. It is much more advanced than physical disk. It happens sometimes that there is need to resize partition in RAID as the following situations:
1. A new RAID virtual drive is added to operating system.
2. Low space of system partition.
3 .We can create more virtual partitions for different usage to make system perform better.
4. When there is need to write data to one small partition.
To fix these problems, we can shrink and extend RAID virtual partitions with partition manager for server.

Tips before shrinking and extending RAID
1. RAID 0, RAID 1, or RAID 5 is almost the same as physical disk to operating system.
2. Even there are several hard disks in RAID array, in Disk Management Tool; it will still be showed as one single physical hard disk.
3. We can only resize virtual partition in one same RAID array.
4. Only hardware RAID virtual partitions can be resized. Before resizing, dynamic disk should be converted to basic disk.
Generally, there will never be too many RAID arrays in one server. It is common that one RAID 1 array for operating system, one or two RAID 5 for data storage. And there are usually several virtual partitions in one RAID array.
The following screenshot is the Windows Server 2003/2008 built-in Disk Management Tool.

It shows every disk is a RAID array, and every virtual partition can be resized. For example, we can shrink partition E: to extend system partition C:.
To resize partition in RAID, we can use professional partition manager server like MiniTool Partition Wizard Server Edition. It is professional and reliable partition manager for Windows server operating systems. It resizes partition in server safely and easily. There is no need to delete or format partition.

Resize RAID with partition manager server
