Some of the suggestions in https://www.lifewire.com/how-to-fix-code-19-errors-2623182 clearly are not applicable, but others might help.
Is the drive still accessible if you boot from a Linux disc or stick (that's free and without danger as long as you don't install it)?
Can you boot from it with a bootable DVD (like the one you made or bought for installing Windows 10)?
Does it work if you don't upgrade to Windows 10 but do a clean install?
When I upgrading from Win 7 64bits to Win 10 64bits my DVD/CD icon disappeared in "This PC". I uninstalled drive and restarted my computer but I still get Error 19, can anyone help me?
