What model PC? Always include the PC model number on any initial problem post. What are you trying to burn? Data? Music? (MP3 or regular music CD) The same optical device drivers in Win 10 and 11 (actually the same since Win 7). Have you tried a different brand/batch of CD-R blanks?  (Don't use RW discs, they can be problematic). I saw a similar burning problem posted on tenforums.com, is that yours?  
I can no longer burn discs since the upgrade to Win 11.I keep getting a medium error message using 3 differentburning software.AshampooNCH ExpressWindows media I use Verbatim discs and also bought a Verbatim externalcd writer and still get the same error message!!! Called Dell support, they did a remote scan and all and suggested that i do a system restore back win 10.Not sure what to do.Do u have any suggestions?Thank You,Gary
