ImDisk Virtual Disk Driver helps you instantly build various disks from thin air. Actually, what ImDisk Virtual Disk Driver does is RAM disks from your available system memory or backup image files of hard disks, floppy or optical drives.

ImDisk is a virtual disk driver for Windows NT/2000/XP/Vista/7/8/8.1 or Windows Server 2003/2008/2012. It can create virtual hard disk, floppy or CD/DVD drives using image files or system memory. The install package installs a console-mode control program called imdisk.exe and a Control Panel applet. After install is finished, type imdisk without parameters for syntax help or double click the ImDisk icon in the Control Panel. It also adds a menu item in Windows Explorer so that you can right-click on a file to mount it as a virtual disk drive. Users of mdconfig in FreeBSD will probably be familiar with the command line syntax of imdisk.exe. The driver, service and control program can be uninstalled using the Add/Remove programs applet in the Control Panel. No reboot is required for installing or uninstalling. An additional driver, awealloc, in this install package supports memory allocation beyond 4 GB limit on 32 bit Windows through address window extension, AWE.

The ImDisk driver supports forwarding I/O requests to third-party image file format handlers or to services on other computers on the network. This makes it possible to boot a machine with NTFS partitions with a Live-CD and use the included devio tool to let ImDisk on another computer running Windows on the network mount the NTFS partition on the machine with a faulty NTFS partition. This way you can recover information and even run chkdsk on drives on machines where Windows does not boot.
