Medalist 3240 and Medalist 2531 Product Manual, Rev. A 11 any drive activity is required, the drive makes a transition to Idle mode. If the host has set the standby timer, the standby countdown continues. If the host has not set the standby timer, the drive remains in Idle mode. If the standby timer reaches zero before any drive activity is required, the drive makes a transition to Standby mode.
12 Medalist 3240 and Medalist 2531 Product Manual, Rev. A 1.8.5 Shock For all shock specifications, it is assumed that the drive is mounted securely with the input shock applied at the drive mounting screws. Shock may be applied in the X, Y or Z axis. For the nonoperating specifications, it is assumed that the read/write heads are positioned in the shipping zone. Note. At power-down, the read/write heads automatically move to the shipping zone.
