Understanding MDF Issues

Typical MDF Opening Challenges

IsoBuster Disappeared

You encounter an error message such as "%%os%% Can't Open MDF Files" when trying to open your MDF. Customarily, this means that IsoBuster is not installed on %%os%%. This will prevent you from double-clicking to open the MDF file because the OS doesn’t know how to handle it.

Tip: Another MDF-related program can be selected to open the file by clicking "Show Apps" and finding the application.

Wrong Version of IsoBuster is Installed

In some cases, you might have a newer (or older) version of a Alcohol 120% Disk Image File Format file that is unsupported by your installed application version. If you've got the wrong version of IsoBuster installed, you'll need to install the correct version. Your Alcohol 120% Disk Image File Format file was probably created by a newer release of IsoBuster than what's currently installed your computer.

Tip: Investigate your MDF file by right-clicking and selecting "Properties" to find clues on what version you need.

Ultimately, most of the difficulties opening MDF files are due to having the wrong version of IsoBuster installed.

Additional MDF Opening Issues

Assuming you have the right IsoBuster version installed, other problems can prevent you from opening MDF files. If you're still experiencing problems opening MDF files, there could be other computer problems. These issues include:

• Windows Registry MDF file paths that are incorrect
• Unintentional removal of the description of the MDF file inside the Windows Registry
• Invalid installation of a MDF-associated program (eg. IsoBuster)
• Your MDF file is corrupted (issues with your Alcohol 120% Disk Image File Format file itself)
• The MDF is infected with a virus
• Device drivers of the hardware associated with your MDF file are corrupt or out-of-date
• Too many applications are open on your PC to load your Alcohol 120% Disk Image File Format file successfully
