3.13 Reliability Features Set
3.13.1 Thermal Management
The drive is designed with Thermal Management features for high reliability.
State-of-the-art mechanical design—Mechanical design is optimized to reduce
the drive’s temperature. State-of-the-art thermal dissipation and windage design
is employed.
Closed loop servo management—Thermal management monitors the drive
temperature and can control servo operations to maintain a stable operating
temperature under high temperature conditions. This is a closed loop servo and
thermal control system.
S.M.A.R.T. HDA Temperature Attribute—The S.M.A.R.T. HDA Temperature
Attribute is supported. The S.M.A.R.T. temperature value is reported within ±3°C
of the base casting temperature.
Ducted airflow—Provides protection to the Read/Write element from heated air.
3.13.2 Internal Environmental Protection System
This dual filter system protects the inside environment of the drive from
contamination. System features include:
Dual Filtration System to ensure fast clean-up times
Directed airflow to maximize mechanical cooling
Increase casting surface area to maximize cooling
Ducted air flow to protect Read Rite elements from heated air
Enhanced heat dissipation
3.13.3 Unrecoverable Errors
If an unrecoverable error is found during the offline scan, the sector is marked. Future
reads from this location will continue to perform full error recovery. However, the
next write to this location will perform a sector test to be sure the media is not
damaged, and the sector relocated if the sector test fails.
3.13.4 Self Test
Self Test is a quick way to determine the operation status of a drive. The following
Self Tests are supported:
Quick Test: Completes in less than two minutes.
Extended Test: Tests all the critical subsystems of the drive.
Conveyance Test: Quickly identifies issues caused by handling damage.
Selective Test: Scans host-defined sections of the drive.
The test may be run to completion or be performed as a background task as the drive
processes other commands from the host. The host may then poll the drive for
runtime status and test results. Since the test is embedded in the drive’s firmware, it
is always available, requires no installation and can be faster and more effective than a
software-based drive test.
