Abstract: A disk drive (106) in a computer system is equipped with a power storage uni t (118) that supplies power to the drive controller (110) when there is a system power interruption, such as a power down or failure. Once the controller is notified that the system power has been interrupted, it will immediately initiate a seek to a reserved location in t he disk drive and store the contents of the cache memory (112) there. After power has been restored to the system, the controller can load the contents of the reserved cylinders back to the cache memory and complete the pending write opeations by writing all of the data items in the cache to their final locations in the drive. Only one write operation is necessary, and this requires much less power than completing a plurality of pending write operations for the items in the cache to scattered locations in the drive.

Abstract: A method for predicting the propreties of a complex hydrocarbon mixture which comprises selecting one or more known chemical, perceptual, physical or performance properties of the complex mixture and creating a training set from reference samples which contain characteristic molecular species present in the mixture. The reference samples are subjected to GC/MS analysis wherein the often collinear data generated are treated by multivariate correlation methods. The training set produces coefficients which are multiplied by the matrix generated from a GC/MS analysis of an unknown mixture to produce a predicted value for the chemical, performance or physical property or groups of properties selected.
