Classification: G06F

Abstract:
A small computer system interface (SCSI) device available for breakdown prediction and self-examination, comprising:a temperature and motor driving sensor, which monitors an inside temperature of said SCSI device and monitors a driving status of a motor of said SCSI device;a power sensor, which monitors SCSI device power and receives a command from a master I2C processor through a I2C processor and monitors a power on/off switch to switch on/off the SCSI device power;a self-monitoring analysis and report technology (SMART) sensor, which monitors a SCSI device status;a device control logic, which reports all previous status reports, error reports and SMART functions to a master I2C processor through a SCSI controller; andan I2C processor, which reports a fault to said master I2C processor through a SCSI channel or an I2C channel, when it is determined, by analyzing all information detected by said temperature and motor driving sensor, said power sensor, said power on/off switch and said SMART sensor, that said I2C processor cannot correct said fault.
