Abstract
Provided is a storage apparatus that detects abnormalities of a hard disk caused by the instantaneous power failure of a low voltage power supply. An effective value reduction detecting circuit transmits a detection signal, when the voltage of a low voltage power supply is lower than specific voltage. CPU memorizes time tto a flash memory. Also, CPU memorizes time t, when recovering low voltage power supplyon proper voltage. Then, CPU computes period of time T, which is time between time tand t. If the computed period of time T is within a range from first period of time Tto the second period of time T, CPU operates a voltage switch and re-supply the power supply to the hard disk. If not within the range, CPU does not re-supply power to the hard disk.
