Why convert MDF to ISO?
ISO is the universal disc-image standard, natively mountable in Windows 10/11, macOS, and Linux with a double-click, while MDF requires DAEMON Tools or Alcohol 120% to mount. Converting to .iso removes the dependency on a third-party virtual drive tool.

.mdfbecause both formats store raw sector data at the same density.
