What usually holds it
A CD or DVD will not come out while a player or burning program holds it. Stop playback and close the burning window. If it is burning, you have to wait — pulling it out mid-burn ruins the disc.
How to eject it
- Close the Explorer window that opened the drive.
- Close the programs that have files on it open.
- Use LetGoFile to see whether anything is still holding it.
- Press Safely Remove again.
Get LetGoFile, look at the drive, and it tells you the name and PID of whatever is holding it.
