The Seagate 3D Defense System—
No One Does More to Protect Your Drives

DRIVE DEFENSE
• QuietStep ramp load technology provides additional

protection against shock while delivering whisper-quiet
load/unload acoustics.

• G-Force Protection guards the drive against nonoperat-

ing shock and prevents damage to the motor, heads,
head-arm, clamp and discs during shipping, handling
and daily operation.

DATA DEFENSE
• ECC (error-correction code) performs fast on-the-fly

data validation and error checking for reliable data
storage and retrieval.

• Safe Sparing ensures data is not compromised by

reserving spare sectors on a drive and substituting
them if defects are detected in other sectors.

• CBDS (continuous background defect scanning)

proactively identifies and eliminates defects.

DIAGNOSTIC DEFENSE
• SeaTools

™

Suite diagnostic software is designed to

reduce drive returns, decrease drive repair costs
and protect data.

• Web-based tools enable users to identify and solve

common system-related issues.

• Enhanced S.M.A.R.T. (Self-Monitoring, Analysis and

Reporting Technology) predicts and prevents problems
transparently before they affect the end user.

• NDST (Enhanced Drive Self-Test) reduces

diagnostic time.
