gBurner Virtual Drive vs TotalMounter

gBurner Virtual Drive is a free Windows utility for creating virtual CD/DVD drives and accessing disc images without burning them to physical discs. It can create up to 16 virtual drives and supports formats including ISO, GBI/GBP, DAA, NRG, MDF/MDS, BIN/CUE, UIF, ISZ, DMG, IMG, and VCD. To mount an image, users open the virtual-drive tray menu, choose the mount command, select an image, and confirm. The same menu provides an unmount command. The download page lists Windows support from version 98 through Windows 11, including 32-bit and 64-bit editions. The free utility is listed at free and is described as free for personal and business use. However, the download comparison identifies mounting an image file to a virtual drive as a gBurner Pro feature rather than a gBurner Free feature. Pro costs $39.95, paid once. The maker says game and program images can run at over 200 times the speed of a conventional CD/DVD-ROM.

TotalMounter is a free Windows utility combining virtual CD/DVD drives, virtual disk mounting, and iSCSI initiator functions. It mounts ISO, CDI, BIN, MDS, MDF, IMG, RAW, CCD, and NRG images. Its virtual CD/DVD burner can write data to an ISO file through CD/DVD burning software. TotalMounter creates and mounts IMG and VHD virtual disks, with AES 256-bit encryption listed for virtual disks. The built-in iSCSI initiator connects to CHAP-protected targets, including those created by iStorage Server, and the program can act as an INetDisk client. Virtual Write allows copying files into a read-only drive without affecting other clients. Up to eight virtual drives are supported. The free edition includes a basic GUI, virtual optical drives, encrypted virtual disks, iSCSI disks, an INetDisk client, and forum support. Listed systems include 32-bit and 64-bit Windows 2000, XP, Server 2003, Vista, Windows 7, and Server 2008. Ethernet is required for INetDisk and iSCSI mounting.
