... (±5%). This gives a detailed report of the error. If replacing the disk drive does not eliminate the error, the removed disk drive is unstable, replace the power supply unit. Check that the jumpers on the PCA are connected correctly. If the DC voltage level is probably not ... within 250 mV. To continue error analysis, refer to 12.6 VDC. If possible, replace the disk drive. Check that the disk drive selection address is set so that the disk drive and host computer operate normally. For a daisy chain connection, check the terminating resistor on all system cables...
