I have posted previous about the my experiences with the annoying sound sound that results from the frequent (every 20 seconds or so on my machine) parking of the C2D MBP HD (120 GB, 5400 in my case.) I have read all that I can find on the web about this "issue." Some sources report that the issue is normal while others seem to feel that some defect is present. I have contacted Apple (1st tier Apple care reps.) twice about the HD parking and both occasions they had never heard of such an issue. They prompted me to take my MBP into an Apple store or an authoized service provider for inspection. I did so and the ASP told me that they would need to send the computer to Apple (don't know why that's just what the man said.) However, I cannot at this time part with the computer for an extended period of time so this is not an option for me. So, I have read about this link to a program that claims to stop the HD parking of these notebook drives by writing small bits of data that is enough to keep the drive from sleeping/parking and thus removing the sound: http://kiza.kcore.de/software/declunk/ Has anyone with my issue had any experience with this program and can testify to its effectiveness and legitimacy? BTW, I have already tried the mirror widget as a fix for this issue and, for whatever reason it does not work for me so please don't bother with the suggestion.
