Combine Unallocated Space into Another Disk?

In some servers, all partitions on the disk are almost full. Some users wonder whether it is possible to merge unallocated space into a partition on a different disk. The answer is no, regardless of the disk partition software used. This is because the size of a physical disk is fixed; a 500GB disk cannot be decreased to 300GB or increased to 700GB. In this situation, you may pindah partisi from the full disk to another one, delete the original partition, and then add the resulting unallocated space to another partition.
