64 bit operating system is quite popular at present and partition magic software is still upgrading constantly with higher safety and greater capability. MiniTool Partition Wizard Server Edition is just one of those partition magic software with powerful functions that supports both 32 and 64bit operating systems. Furthermore, MiniTool Partition Wizard is totally free for home and personal user.
Advantages and disadvantages of 64 bit operating system:
A common misconception is that 64-bit architectures are no better than 32-bit architectures unless the computer has more than 4 GB of main memory. Some operating systems and certain hardware configurations limit the physical memory space to 3 GB on IA-32 systems, due to much of the 3–4 GB region being reserved for hardware addressing; see 3 GB barrier. This is not present in 64-bit architectures, which can use 4 GB of memory and more. Some programs such as data encryption software can benefit greatly from 64-bit registers (if the software is 64-bit compiled) and effectively execute 3 to 5 times faster on 64-bit than on 32-bit.
The main disadvantage of 64-bit architectures is that relative to 32-bit architectures, the same data occupies more space in memory (due to swollen pointers and possibly other types and alignment padding). This increases the memory requirements of a given process and can have implications for efficient processor cache utilization. Maintaining a partial 32-bit model is one way to handle this and is in general reasonably effective. For example, the z/OS operating system takes this approach currently, requiring program code to reside in 31-bit address spaces (the high order bit is not used in address calculation on the underlying hardware platform) while data objects can optionally reside in 64-bit regions.
In this interface, user could change cluster by click the drop-down list and choose wanted size.
For example, change the cluster as 32. Then click "Yes". Thus, this operation is successfully finished.
