1.0 Introduction

This manual describes the functional, mechanical and interface specifications for the following Seagate

DB35.3 Series PATA model drives:

ST3750840ACE ST3320820ACE

ST3500830ACE ST3300820ACE

ST3400820ACE ST3250820ACE

These drives provide the following key features:

• 7,200-RPM spindle speed.

• High instantaneous (burst) data transfer rates (up to 100 Mbytes per second) using Ultra DMA mode 5.

• Perpendicular recording technology. Tunneling Giant magnetoresistive (TGMR) recording heads and Enhanced Partial Response-Maximum Likelihood (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.

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

• 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).
