Physical disc present but not recognized – Dirty or scratched disc, failing drive, or incorrect disc for the module you’re trying to open.
Virtual drive conflict – If you mounted an .iso or .nrg image using Daemon Tools, Alcohol 120%, or Windows’ native mount, AutoData may reject it (detecting it as a virtual drive).
Outdated software – Old versions (e.g., AutoData 3.x or 4.x) expect a physical disc even if installed to HDD.
Corrupted installation – Missing registry keys or altered .exe files can trigger re-verification.
Drive letter change – If your optical drive letter changed (e.g., after adding a new hard drive), the software may not find the expected drive.

Some older Autodata versions (3.x and 4.x) have a known "crack" that involves replacing the Autodata.exe with a patched version that removes the optical verification call. These files exist on legacy automotive forums (e.g., MHH Auto, Digital Kaos, or DK Workshop).

How to identify a legitimate patched file:

File size: The original Autodata.exe is ~2.5MB. A cracked version is ~2.5MB but with a modified hex string.
Look for a NOCD or FIX folder included with a "Readme.txt."

To apply:

Install Autodata normally from your original disc (the data files are fine).
Do not run the program yet.
Backup the original Autodata.exe (rename it to Autodata_original.exe).
Copy the patched Autodata.exe into the installation folder (typically C:\Program Files (x86)\Autodata Limited\Autodata\).
Run the program. It should no longer ask for the disc.

Warning: 90% of "cracked" files available on random file-sharing sites contain malware (keyloggers, crypto miners). Only attempt this inside a virtual machine or on an offline PC. Better yet, don't do it at all.
