With my PC out of my sight I'm happy to have a very silent System with no Sound whatsoever, even not from HardDisk.
BUT this can be a hazard if you want to know about activity of the Disc. So, I'm looking for a simple LED in the Panel in the first step and the same with different LED's for different Partitions.
I searched quite a lot and found some solutions for MS's Windows, but since I don't like Win.
