CDEmu vs RaiDrive

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.

RaiDrive mounts cloud storage as a drive on a Windows or Linux computer, letting users open, edit, and save cloud files from desktop applications.
