I have one 11GB hard disk split into two partitions: C and D. I configured the C partition with 9.5GB of hard disk space and the D partition with 1.5GB of hard disk space. The C partition hosts my Windows 2000 Professional installation and all my applications. To archive some documents, I needed more disk space on my D partition; I had only 200MB of available disk space and needed 800MB to perform this task.
To solve my problem, I used PowerQuest's PartitionMagic Pro 6.0. At first, I was concerned about losing information. However, I was surprised by how easily I was able to resize my partitions and, more important, by how reliable and safe the process was.
To use this product to resize your hard disk partitions, start PartitionMagic, then select the partition that has available disk space that you want to free up (the C partition in my case). From the Operations menu, select the Resize/Move option. In the resulting dialog box, specify in megabytes the amount of disk space that you want to make available, then click OK. Next, select the partition that you want to increase the size of (the D partition in my case). From the Operations menu, select the Resize/Move option, and in the resulting dialog box, specify the new size for the partition. I specified that the software give all the available disk space to the partition. Click OK, and the software will apply the changes.
