Shrink Server 2003 partition without data loss

As a tech consultant, blogger and forum moderator, I was asked many times 'is it possible to shrink a partition on 2003 Server without destroying data'. Of course, the answer is yes, in this article, I want to share some experience about how to shrink Server 2003 partitions.

Why shrink Server 2003 partition

Many people complain that the default partition configuration in brand Server is illogical, for example,

  • System C drive is too small
  • Data partition is too large and waste space
  • Due to basic disk limitation, three Primary partitions have been used, they cannot create new partitions.

Some people encountered the problem, such as,

- When installing Windows 2003 Server, they forget to create more partitions and installed Operating System to C drive with all disk space.

- Some administrators created 2 or 3 partitions, but they found that it is still insufficient, to manage files more efficient, they need more partitions, but all updates, applications and Server components have been installed, they cannot suffer from starting over.

- Another annoying thing from Microsoft is that Windows continuously download updates, hundreds of MB files are asked to install, neverending.

- Many applications throw files to system partition even if you change the default installation path to other drive.

Don't worry, I'll give you an 'effective prescription' to get rid of the headache.
