The program can't find any usable optical drives.

Post by Ladyknightthebrave » Sat May 23, 2020 12:28 am

Although I hadn't made any changes to my setup I am suddenly getting this message when I open MakeMKV

Operating system blocked access to optical drive "\Device\CdRom0". Program needs to be run as administrator to access the drive.
The program can't find any usable optical drives.

With our without a disc the program isn't recognizing the disc drive. I tried running the program as an administrator I tried updating to the latest version of the software and I tried an older version. Same issue. And I made sure my antivirus software wasn't blocking the program for some reason, it isn't.

I'm running Windows 10. Please help

A google earch for "Windows ransomware exception" should find a lot of information on this topic. The Fall 2019 update to Windows 10 defaults to marking all newly-installed programs as unsafe (unless you got them from Microsoft-approved sources), and defaults to blocking access to devices. You need to add MakeMKV's programs as exceptions.
