5 (Optional) Under Advanced options, set the Bus type for the hard disk to IDE, SCSI, SATA, or
NVMe.
Note If the guest operating system does not support NVMe, the NVMe option appears
unavailable.
Changing this setting is recommended only for advanced users. Fusion selects the bus type
that is most appropriate for the virtual machine guest operating system.
6 Set your disk space configuration, depending on the constraints of the file system.
Option Description
Pre-allocate disk space Can give better performance for your virtual machine. If you allocate all
the disk now, you cannot use the VMware Tools shrink disk feature later.
Allocating all disk space now is a time-consuming operation that cannot be
canceled. Also, the allocation process requires as much physical disk space
as you specify for the virtual disk.
Split disk into multiple files Default. Some file systems, such as FAT and UFS, cannot support very large
files. Use this option if your virtual machine will be used in a hard drive with
a file system that does not support very large files. This option splits your
virtual disk into multiple files. Also, use this option if you might place the
virtual machine on an external FAT drive or if you might move the virtual
machine to an external drive.
7 Apply the changes and choose automatic or manual partition resize for Windows guests.
Option
Description
Click Apply. For Windows guests, the partition is automatically resized when the hard disk
is resized.
Click Apply while pressing the

The hard disk is resized but the partition is not. To manually resize the
partition of the guest, see Resize a Windows Partition with the Disk
Management Tool.

Fusion displays a progress dialog box as it rebuilds the virtual disk.
Resize a Windows Partition with the Disk Management Tool
When you enlarge your virtual hard disk, you must also enlarge your guest operating system's
partition to take advantage of the additional space.
Fusion resizes the guest operating system's partition when you resize the virtual hard disk. If you
held down the Option key when you clicked Apply to resize the disk, you can manually resize
the Windows partition. For Windows Vista and Windows 7 or later, you can use the operating
system's Disk Management tool to resize a partition.
