1.0 Introduction

This manual describes the functional, mechanical and interface specifications
for Seagate
ST330012A model drives. These drives provide the following key features:

• 5,400-RPM performance class 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 technology,
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.

®

U7 ST3120020A, ST380022A, ST360012A, ST340012A, and

• 350 Gs nonoperating shock.

®

• The innovative, shock-absorbing SeaShield

cover protects the drive against

electrostatic d ischarge (ESD) an d other handlin g damage. It also includes
installation instructions and jumper settings.

• SeaTools diagnostic software performs a drive self-test that eliminates
unnecessary drive returns.

• The 3D Def ense System™, which in cludes Drive Defens e, Data Defense,
and Diagnostic De fense, offers the industry ’s most comp rehensiv e 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).
