PPC-HDD(MS)A User's Guide
Average Life of the Hard Disk Drive The average life of the hard disk drive is 5 years or 20,000 hours of energized time whichever reached first.
High-temperature Detection Feature Using the hard disk unit in a high-temperature environment shortens the life of the hard disk. The hard
disk unit has a high-temperature detection feature to detect an ambient operating temperature of 47±3°C
or higher using the high-temperature detection function of bus interface driver software. Use this feature
as a means of warning when the hard disk unit is being used at high temperature.
When high-temperature detection is not necessary, you can disable the high-temperature detection
function by setting with the bus interface driver software. In that case, high-temperature detection is not
performed.
For details on this function, refer to the Bus Interface Driver User's Manual [PPC-CPU686(MS)-MU or
PPC-CPU852(MS)-MU, separately priced].
