1.0 Introduction

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

Barracuda® 7200.10 PATA model drives:

ST3750840A ST3320820A

ST3750640A ST3320620A

ST3500830A ST3300820A

ST3500630A ST3300620A

ST3400820A ST3250820A

ST3400620A ST3200820A

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.

• Tunneling Giant magnetoresistive (TGMR) 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.

• 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).
