6.6 Reliability

6.6.1 Data integrity

• Probability of not recovering data is 1 in 10
• ECC implementation
On-the-fly correction performed as a part of read channel function recovers up to 16 symbols of error in 1 sector (1 symbol is
10 bits).

6.6.2 Cable noise interference

To avoid any degradation of performance throughput or error rate 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.

6.6.3 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 hold 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 the required power-off sequence.
Service life of the drive is approximately 5 years or 20,000 power on hours, whichever comes first, under the fol-
lowing 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.

6.6.4 Preventive maintenance

None

6.6.5 Load/Unload

The product supports a minimum of 600,000 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:
• Hard reset
