### Introduction

Microsoft offers SMARTDrive version 4.2 as an alternative to SMARTDrive version 4.1 for those customers who want more conservative disk caching and are willing to accept slower disk-write performance. The enclosed PD0805 disk contains SMARTDrive version 4.2 and SMARTDRV.TXT, which includes installation instructions and parameter descriptions. You can view SMARTDRV.TXT in MS-DOS Editor.

      NOTE: MS-DOS 6 Upgrade will continue to include SMARTDrive version
      4.1.

### New Features

SMARTDrive version 4.2 includes the following new features:

- A default option to write the contents of the write-cache to disk before returning to the MS-DOS command prompt after completing an MS-DOS command or exiting an MS-DOS program or MS-DOS-based application.
- An /N switch that disables the default "write write-cache contents to disk" option noted above.
- A new /X switch that disables write-caching for all drives.
