Which software to resize 2003 Server partitions?

Partition Magic

Partition Magic is the first and most famous partitioning software, but since being acquired by Symantec, Partition Magic has not been upgraded. So it is not possible to extend, resize server partition under any advanced Operating System, such as Windows 2003, 2008, etc. Furthermore, it is no longer for selling.

Diskpart.exe

Diskpart.exe is a command line built in Windows 2003, which is free, but it is not recommended to resize partition on Server 2003, as it has many limitations, such as:

  • Only DATA partition can be extended.
  • The partition you want to extend must be formatted as NTFS.
  • The unallocated space for extension must be the next contiguous space on the same disk.
  • You cannot extend the partition if the system page file is located.
  • Comparing with graphical user interface software, command line is hard to use for many users.
  • Operations cannot be undone, incorrect operations are very likely lead to data loss.

NIUBI Partition Editor is only program that integrated Roll-Back technology to ensure 100% data safety. It automatically roll back the server to the status before resizing in ONE second, if any software error or hardware issue such as power failure occur during resizing. So I always recommend this tool to resize Windows server partitions.

When system C drive if full or running out of space, you'd better resize partition and extend it, as low free disk space may cause system running slower, reboot or crash, and you cannot install updates or applications.

No Server partitioning software has the ablity to extend a drive by taking space from other physical hard disk.
