ST9144 Family Installation Guide, Rev. B 1 Read before you begin... Verify that system power is off before attempting any installation. Observe static discharge precautions. Keep the drive in its static-shielded bag until you are ready to complete the installa- tion. • Do not touch the circuit board or the I/O connector pins. • Always handle the drive by the edge or frame. Never apply pressure to the circuit board or to the drive top cover. Use a grounded wrist strap at your workstation; if una

2 ST9144 Family Installation Guide, Rev. B Shipping. When transporting or shipping a drive, you must use a Seagate-approved container. Keep your original box. They are easily identified by the Seagate Approved Package label. Ship- ping a drive in a non-approved container voids the drive warranty. Seagate service centers may refuse receipt of components im- properly packaged or obviously damaged in transit. Call your authorized Seagate distributor to purchase additional boxes.

These delays can also be specified by the user via the system Setup utility. Each time the drive performs an Active function (read, write or seek) the Idle timer is re-initialized, and begins the countdown from the specified delay time to zero. If the Idle timer reaches zero before any drive activity is required, the drive transi
