Disabling IMAPI in Vista

There is no per-se disabling of IMAPI in Vista. IMAPI in Vista is a DLL (unlike XP where IMAPIv1 is a service).

However if you explain us the user scenario you are trying to achieve we can probably help.

Write-protected media, except for file system write protection, should indeed not be written by the shell integration of IMAPI. Drag'n'dropping file to such media, I get a prompt to insert a writable media and the read-only media is ejected. Exception is if you have already file(s) in the staging folder, then you can continue to edit the content of the staging folder. But again, this should be the shell integration of IMAPI and not IMAPI itself.

Is this consistent with your observations?

There is no way to disable the shell integration of IMAPI for a particular device or drive letter.

There is a group policy to disable burning from shell (both live file system and mastered, totally), this is “disable CD Burning” policy in Explorer Group Policy settings. This further requires to restarts Windows Explorer. I am guessing this is not a solution for your scenario.

As explained earlier in this thread, there is no longer an IMAPI service in Windows Vista. The IMAPI service that existed in Windows XP was not used for Vista. Hence there is not service interfering with 3rd party software that you can disable.

Power calibration error is a kind of error that also occurs as a burner ages and the laser lense weakens. It is then no longer possible for the electronic to compensate for the loss of power and the burner concludes to a power calibration error. I suggest trying to replace the device.
