you can turn down the sensitivity in the Thinkvantage software regarding head parking. This feature is added to prevent the harddrive head crashing into the platter, since the density of data storage on new harddrive have experienced exponential growth, and the number of platters used have also increased. Therefore, fault tolerance have also decreased, the number of G shock it can experience during the harddrive spinning before catastrophic failure have also decreased. As there is only a couple of micrometer of space between the head and the spinning platter, so a sudden increase in G will cause head bump into it the spinning platter.
laptop harddrive nowadays is one of the most astonishing engineering marvel to come to the consumer market.... if you use a microscope to look at the surface of the platter, the smoothiness is comparable to the gyroscopes balls used in Hubble telescope.
