Arsenal Image Mounter vs CDEmu

Arsenal Image Mounter mounts disk image contents as complete disks in Windows, making disk-specific features accessible. Free Mode includes temporary write support, command-line executables, PowerShell modules, and tools to identify, unlock, decrypt, disable, or suspend BitLocker-protected volumes. Professional Mode can start virtual machines from disk images, physical disks, or remotely connected disks. It adds Recon Reports for triage and can expose NTFS metadata, slack, and unallocated space through file system driver bypass mode. Listed formats include raw and DMG; support for AFF4, E01, limited Ex01, and S01 depends on available libraries, alongside several virtual machine disk formats. Professional Mode connects to remote disks over a network using AIM Remote Agent. Arsenal recommends Windows 10 version 1703 or later, Windows 11, or Windows Server 2016/2019 x64 with.NET 10 on bare metal for full functionality. Linux support is described for a CLI and offline license activation. Free Mode costs nothing; paid plans start at $907 a year.

CDEmu emulates optical drives and discs on Linux, including CD-ROM and DVD-ROM media. Its kernel module provides a virtual SCSI host adapter that connects the Linux kernel with a userspace daemon, while libMirage gives access to many optical image formats, including MDS, CUE, BIN, ISO, NRG, UDF, DMG, CSO, GZ, DAA, and ISZ. Emulated media can be mounted in Linux, with automounting available. The project also describes experimental CD-R and DVD+R recording emulation, allowing blank virtual discs to be written with disc-burning software. Users can load and unload devices, check device status, and manage debug masks through command-line or GTK clients. The daemon exposes methods over D-BUS and can register on the session or system bus. System-bus use needs special permissions; session-bus use requires read and write access to the VHBA control device. CDEmu is free under the GNU GPL version 2 or later. The project lists official source tarballs and Linux distribution packages; third-party packages are not verified or formally supported.
