Abstract
A computer system is disclosed comprising a disk drive comprising a head stack assembly (HSA), the HSA comprising a spindle motor for rotating at least one disk, and at least one head actuated over the disk. The computer system further comprises a host coupled to the disk drive, wherein the host comprises a microprocessor operable to first boot the host by reading boot data from a secondary storage device. After first booting the host, the microprocessor commands the disk drive to accumulate performance data for the HSA, and after accumulating the performance data, the microprocessor second boots the host by reading boot data from the HSA.
