Introduction

This manual describes the functional, mechanical and interface specifi-

cations for the ST380021A, ST360021A, ST340016A and ST320011A.

These drives provide the following key features:

•7,200-RPM spindle speed and 2-Mbyte buffer combine for superior

desktop performance

•High instantaneous (burst) data-transfer rates (up to 100 Mbytes per

second) using Ultra DMA mode 5

•Giant magnetoresistive (GMR) recording heads and EPRML technol-

ogy, which provide the drives with increased areal density

•State-of-the-art cache and on-the-fly error-correction algorithms

•Full-track multiple-sector transfer capability without local processor

intervention

•Quiet operation

•350 Gs nonoperating shock

•The innovative, shock-absorbing SeaShield®cover protects the drive

against electrostatic discharge (ESD) and other handling damage. It

also includes installation instructions and jumper settings.

•SeaToolsdiagnosticsoftwareperformsadriveself-test thateliminates

unnecessary drive returns.

•The 3D Defense System™, which includes Drive Defense, Data

Defense and Diagnostic Defense, offers the industry’s most compre-

hensive protection for disc drives.

•Support for S.M.A.R.T. drive monitoring and reporting

•Support for Read Multiple and Write Multiple commands

•Support for autodetection of master/slave drives that use cable select

(CSEL)
