The compact disc (CD, DVD, Blu-Ray) has been around for at least two decades - and yet if my computer has a problem reading a disc it will continue spinning away until I physically eject the disc by pressing the hardware button on the drive.

Killing media player applications or processes doesn't stop the drive-grunting and software eject commands are ignored and usually freeze up the My Computer window if attempted*. I have experienced this with various discs over various machines over various versions of Windows from 95 to 7.

So my question is: Is there a fundamental reason why I have to press the hardware eject button whenever a compact disc or disc sector turns out to be defective?

It's not as if the applications or operating system are completely unaware of the disc read errors. Unless neither the OS or application stack are bothering to actually cap the read/seek/response delay at a Hard-QoS ceiling?

* Actually almost any resource displayed at the My Computer level can freeze up Explorer in this fashion if you are unlucky (internal, external, network, virtual, etc). It has got somewhat better with Windows 7 though; I don't fear double-clicking My Computer when the corporate network drives are down anymore.

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.If this question can be reworded to fit the rules in the help center, please edit the question.

    
It wasn't opinion-based. The problem happens. I've seen happen to many people on many computers. Hence it was a technical knowledge-base question asking why does it occur. "Primarily opinion-based" is the most abused close flag in the entire stack network. But whatever; the bigger the Stack, the more arbitrary the mods. –  LateralFractal Sep 25 at 11:05
