Approaches for determining the likelihood that a hard-disk drive (HDD) will experience an imminent error in operation, and preventing the same, using an atmospheric pressure sensor are provided. The HDD comprises an atmospheric pressure sensor capable of determining the altitude at which the HDD is currently located. The HDD also comprises a risk assessment component capable of (a) determining an expression of how likely it is that the HDD will experience an imminent error in operation based, at least in part, upon the current altitude of the HDD, and (b) communicating the expression to a user of the HDD. The HDD may optionally comprise one or more of a particle counter, differential pressure sensor, and a chemical vapor sensor for use by the risk assessment component. If the HDD is above a particular altitude, the Thermal Fly-Height control settings of the heads may be adjusted to reduce risk of error.
