The present invention provides a disk drive system employing a method of analyzing disk drive failure wherein a disk drive target controller is logically connected to an initiator on a SCSI bus. The method includes storing SCSI bus state information upon the receipt of a SCSI bus reset condition. SCSI bus state information is maintained, wherein the SCSI bus state information corresponds to the logical connection between the initiator and the disk drive target controller on the SCSI bus. A SCSI bus reset condition is detected. The maintained SCSI bus state information is stored upon detection of the SCSI bus reset condition. Actions are preformed to reset devices connected to the SCSI bus, including resetting the disk drive target controller. The SCSI bus state information can be subsequently analyzed to aid in determining the cause of the SCSI bus reset condition.
