Abstract
According to one embodiment, a magnetic disk drive apparatus includes a nonvolatile memory which serves as a cache memory when data is recorded in a magnetic disk which records data, a threshold value setting unit which sets a threshold value of a storable size of the nonvolatile memory in accordance with count of the shock detected by a detector which detects shock applied to a main body, calculator which calculates a sum of a size of data which has been written in the nonvolatile memory and a size of data to be written, determination section which determines whether or not the calculated data size is greater than the threshold value, moving unit which moves the data written in the nonvolatile memory to the magnetic disk, when it is determined that calculated data size is greater than the threshold value, and writing section which writs the data in the nonvolatile memory.
