Foobar Headache

Whenever I click on “open audio CD” it freezes the computer with the hard drive light constantly on.

By restarting I didn’t damage the files in the drive in any way right? I was listening to music from the drive. Even if they were damaged, I would know about it right? LIke there can’t be subtle damage where only a few zeros and ones are changed and I it just played with some static noise which I didn’t pick up on later inspection? LIke the computer would tell me when files on the HDDs are damaged would it?
