6.3Reliability

6.3.1Data reliability

ŸProbability of not recovering data is 1 in 1014 bits read

ŸECC implementation

On-the-fly correction performed as a part of read channel function recovers up to16 symbols of error in 1 sector (1 symbol is 10 bits).

6.3.2Failure prediction (S.M.A.R.T.)

The drive supports 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" and in Section 13.32, "S.M.A.R.T. Function Set (B0h)"

6.3.3Cable 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.

6.3.4Service life and usage condition

The drive is designed to be used under the following conditions:

ŸThe drive should be operated within specifications of shock, vibration, temperature, humidity, altitude, and magnetic field.

ŸThe drive should be protected from ESD.

ŸThe breathing hole in the top cover of the drive should not be covered.

ŸForce should not be applied to the cover of the drive.

ŸThe specified power requirements of the drive should be satisfied.

ŸThe drive frame should be grounded electrically to the system through four screws.

ŸThe drive should be mounted with the recommended screw depth and torque.

ŸThe interface physical and electrical requirements of the drive should satisfy Serial ATA Revision 2.6 .

Ÿ The power-off sequence of the drive should comply with the 6 .3 .6.2,"Required power-off sequence.”

Service life of the drive is approximately 5 years or 20,000 power on hours, whichever comes first, under the following assumptions:

ŸLess than 333 power on hours per month.

ŸSeeking/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.
