most appropriate for the virtual machine guest operating system.
9 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.
10 Click Apply.
The hard disk is created. View the new hard disk in Settings > Removable Devices of the virtual
machine.
Resize a Hard Disk
You can increase the usable space in a virtual hard disk. You cannot reduce the size of a hard disk. You
cannot make a blank hard disk smaller after it has been formatted.
Prerequisites
Having manual or AutoProtect snapshots in your virtual machine prevents you from making changes to a
virtual hard disk. You must delete the snapshots before you can make a change.
Shut down or power off the virtual machine. You cannot change the setting while the virtual machine is
powered on or suspended.
Procedure
1 Select Window > Virtual Machine Library.
2 Select a virtual machine in the Virtual Machine Library window and click Settings.
3 In the Settings window, click the hard disk you want to resize.
4 Use the Disk size slider to set the new size.
The maximum disk size for any hard disk is 8TB.
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 is disabled.
Changing this setting is recommended only for advanced users. Fusion selects the bus type that is
