The specifications in the table below are defined as follows: Track-to-track seek time is an average of all possible single-track seeks in both directions. Average seek time is a true statistical random average of at least 5,000 measurements of seeks between random tracks, less overhead. Typical seek times (msec)

G 2.9.2 Conducted noise Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on the +12 volt line or an equivalent 15-ohm resistive load on the +5 volt line. Using 12-volt power, the drive is expected to operate with a maximum of 120 mV peak-to-peak square-wave injected noise at up to 10 MHz. Using 5-volt power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave injec
