PREFACE

This manual describes the MPA3017AT/MPA3026AT/MPA3035AT/MPA3043AT/MPA3052AT, a 3.5-inch hard disk drive with a BUILT-IN controller that is compatible with the ATA interface.

This manual explains, in detail, how to incorporate the hard disk drives into user systems.

This manual assumes that users have a basic knowledge of hard disk drives and their application in computer systems.

This manual consists of the following six chapters:

Chapter 1	DEVICE OVERVIEW
Chapter 2	DEVICE CONFIGURATION
Chapter 3	INSTALLATION CONDITIONS
Chapter 4	THEORY OF DEVICE OPERATION
Chapter 5	INTERFACE
Chapter 6	OPERATIONS
Chapter 7	MISCELLANEOUS

When the unrecoverable error occurs during the write operation, the command execution is stopped. Then, when the drive receives the next command, it generates an interrupt of abnormal end. However an interrupt of abnormal end is not generated when a write automatic assignment succeeds. However, since the host may issue several write commands before the drive generates an interrupt of abnormal end, the host cannot recognize that the occurred error is for which command generally. Therefore, it is very hard to retry the unrecoverable write error for the host in the write cache operation generally. So, take care to use the write cache function Page 61-2-411-8603 Reader Comment Form FUJITSU LIMITED
