摘要:
Even in the case of a full hang state where a command to reset software is entirely ineffective, memory dump can be stored even if there is no in-circuit emulator. An HDD itself monitors a command execution time, that is, the time between reception of a command from a host computer and completion of the process of the command. If the HDD judges that it has taken an abnormally long time, a memory dump will be automatically stored on a reserved area on a disk. The memory dump can be read out from the disk at any time so that an analysis can be made.
