1.0Introduction

This manual describes the functional, mechanical and interface specifications for Seagate® U7 ST3120020A, ST380022A, ST360012A, ST340012A, and 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.

•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.

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

•The 3D Defense System™, which includes Drive Defense, Data Defense, and Diagnostic Defense, offers the industry’s most comprehensive 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).
