6.3.2 Failure prediction (S.M.A.R.T.)
The drive supports the Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) function. The details are
described in Section 11.8, "S.M.A.R.T. Function" on page 73 and Section 13.38, "S.M.A.R.T. Function Set (B0h)"
on page 156.
6.3.3 Cable noise interference
To avoid any degradation of performance throughput or error when the interface cable is routed on top or comes in
contact with the HDA assembly, the drive must be grounded electrically to the system frame by four screws. The
common mode noise or voltage level difference between the system frame and power cable ground or AT interface
cable ground should be in the allowable level specified in the power requirement section.
6.3.4 Service life and usage condition
The drive is designed to be used under the following conditions:
•
The drive should be operated within specifications of shock, vibration, temperature, humidity, altitude, and
magnetic field.
•
The drive should be protected from ESD.
•
The breathing hole in the top cover of the drive should not be covered.
•
Force should not be applied to the cover of the drive.
•
The specified power requirements of the drive should be satisfied.
•
The drive frame should be grounded electrically to the system through four screws.
•
The drive should be mounted with the recommended screw depth and torque.
•
The interface physical and electrical requirements of the drive should satisfy ATA-6.
•
The power-off sequence of the drive should comply with the required power off sequence described in Sec-
tion 6.3.6.2, "Required Power-Off Sequence" on page 26.
Service life of the drive is approximately 5 years or 20,000 power on hours, which comes first, under the following
assumptions:
•
Less than 333 power on hours per month.
•
Seeking/Writing/Reading operation is less than 20% of power on hours.
This does not represent any warranty or warranty period. Applicable warranty and warranty period are covered by
the purchase agreement.
6.3.5 Preventive maintenance
None
6.3.6 Load/unload
The product supports a minimum of 300,000 normal load/unloads.
Load/unload is a functional mechanism of the hard disk drive. It is controlled by the drive micro code. Specifically,
unloading of the heads is invoked by the following commands:
•
