Support for Virtual and Real Disks

This section lists the types of disks that can be used by Parallels virtual machines and provides the information about basic operations that you can perform with these disks.

Supported Types of Hard Disks

Parallels virtual machines use virtual hard disks as their hard disks.

Virtual Hard Disks

The capacity of a virtual hard disk can be set from 100 MB and up to 2 TB.

Virtual hard disks can be either plain or expanding . When you create a virtual machine in Express Windows or Express Linux , or Typical mode (in New Virtual Machine Wizard ), the disk is created in the expanding format.

plain	A plain virtual hard disk image file has a fixed size. The size is determined when the disk is created.
expanding	An expanding virtual hard disk image file is stored on the Parallels server and is small initially. Its size grows as you add applications and data to the virtual hard disk in the guest OS.

Split disks

A virtual disk of either format can be a single-piece disk or a split disk. A split disk is cut into 2 GB pieces and is stored as a single .hdd file.

CD/DVD Discs and Their Images

A virtual machine can access real CD/DVD discs and images of CD/DVD discs.

There are no limitations on using multisession CD/DVD discs. Virtual machines can play back audio CDs without any limitations on copy-protected discs.

Parallels virtual machines support CD/DVD disc images in the ISO and DMG formats. They may also support CD/DVD disc images in the CUE and CCD formats.

Floppy Disks and Floppy Disk Images

Parallels virtual machines can use two types of floppy disks:

Real diskettes inserted into a real floppy disk drive that is connected to the virtual machine.
Floppy disk image files with the .fdd extension connected to the virtual machine.

Floppy disk images are treated like real diskettes. Virtual machines support floppy disk image files that have .fdd extension and 1.44 MB size.

Note: Parallels Management Console cannot create images of real diskettes.
