The inclusion of antivirus software
`
`with the DOS 6 upgrade will undoubtedly
`raise user awareness of the need for pro-
`tection against computer viruses. This
`will more than likely spur sales of more
`sophisticated programs, especially those
`that provide the features necessary for
`protecting an entire workplace. Whether
`you decide to stick with the software Mi-
`crosoft has given you or upgrade to more
`feature-rich programs, you now have ab-
`solutely no excuse to leave your system
`unprotected.

`
`Microsoft provides two utilities with
`DOS 6 that extract the maximum perfor-
`mance from your disk drive: Defrag and
`SmartDrive. Defrag optimizes a disk’s ca-
`pacity by reorganizing the physical place-
`ment of the files and directories on the
`drive. SmartDrive speeds your com-
`puter’s access to its DOS drives by retain-
`ing the most frequently accessed infor-
`mation from those drives in memory.
`Although Microsoft distributed Smart-
`'Drive with DOS 5,
`the company has
`added a new feature that provides even
`better performance.
`
`IIEHIABBIIIB unsuuzss FILE sun!
`It is almost inevitable that with normal
`use files on a DOS drive will become frag-
`mented. This occurs when the contents
`of a file are stored in noncontiguous areas
`of the drive. While this condition is not
`dangerous to your files, it requires more
`movement of the disk drive’s read/write
`heads and slows down access to data.
`DOS 6’s Defrag reorders—-or defrag-
`i:uents—the files on a drive, ensuring that
`each file occupies a single, contiguous
`chunk of disk space. DOS can then access
`the defragmented files more quickly.
`Defrag is a subset of the SpeedDisk
`utility found in The Norton Utilities from
`Symantec Corp. (800-825-2504), and its
`command line and user interface are very
`similar to SpeedDisk’s. In fact, with the
`exception of a few command-line param-
`140 PCMAGAZINE Al‘-“RlL13.1993
`
`cur: smv
`
`DOS 6
`
`eters, menu selections. and defragmenta-
`tion strategies (such as file placement
`specification and the defragmentation of
`free disk space), Defrag fully measures
`up to SpeedDisk’s reputation as a quality
`defragmentation utility.
`Defrag also performs optimizations
`on drives compressed with Doublespace.
`Although it does not perform full defrag-
`mentation, Defrag is
`the only utility now
`available with this ca-
`
`Compared to Defrag‘s two strategies,.
`both No1'ton’s SpeedDisk and Compress
`(in Central Point Software's PC-Tools’,
`800-825-2504) offer five strategies that-
`give you greater control over perfor-
`mance and speed. Another option lets
`you decide which files to leave in place.
`But you can achieve virtually the same
`effect with Defrag by marking a file as
`“hidden."

`Defrag

`unfragmenting
`Defrag performs the
`minimum amount of work needed to re-
`
`organize the files, usually leaving areas
`of free disk space scattered across the
`disk. With full optimization. Defrag rear-
`ranges all of the files and directories.
`compacting the used space into one area.
`and leaving a single. large free space on
`the hard disk. However, full optimization
`usually requires significantly more time
`to execute lhanjust unfragmenting files.
`Another option lets you sort directory
`entries on the hard disk in ascending or
`"descending order by any combination of
`name. extension, size. or date and time.
`While DOS 5 can view directory entries
`in a sorted order (an option on the DIR
`command),
`this feature actually stores
`the directory entries in sorted order.

`fast
`today’s
`drives are. they all can be considered slow
`when compared to the CPU. Relatively
`speaking. your computer sits there twid-
`dling its thumbs while the disk drive takes
`interminable milliseconds retrieving a
`piece of data from the hard disk. How-
`ever. SmartDrive can significantly speed
`access to information on a disk drive.
`SmartDrive performs this magic by re-
`taining the most frequently accessed por-
`tions of the disk in memory. When a pro-
`gram (or DOS) requests a read from the
`disk, and SmartDrive notes that the infor-
`mation is already in memory, it simply
`transfers the data from its buffer to the
`
`program’s buffer.
`Originally introduced with Windows, _
`Microsoft also shipped SmartDrive with
`DOS 5. The major improve-
`ment
`in DOS 6's version of
`SmartDrive is a new feature
`
`called delayed write, or write
`caching. Write caching cap-
`tures the results of disk writes,
`
`and physically writes them to

`
`DOS 6
`
`gram has requested a write, but before
`the physical write occurs, the data is irre-
`trievably lost.
`A second enhancement
`
`to Smart-
`
`Drive is called double buffering, a feature
`allows Sn1artDrive to interact properly
`with bus-mastering disk controllers.
`In DOS 6, SmartDrive is no longer a
`device driver. Microsoft has reconfigured
`the utility as an executable file, allowing
`you to install SmartDrive from AUTO-
`EXECBAT or from the DOS command
`
`line. In addition, after you have started
`SmartDrive, you can now request a dis-
`play of its status, flush the cache, and start
`or stop caching on individual drives with
`a simple command.
`Just as it has done with the other utili-
`
`ties included in the DOS 6 package, Mi-
`crosoft has limited SmartDrive’s flexibil-
`
`ity, while preserving its performance. For
`example, in an unusual move, Microsoft
`removed the option that allowed you to
`place SmartDrive‘s cache into expanded
`memory. Since you can use only ex-
`tended memory for the cache buffer. you
`cannot run Srr1artDrive unless your sys-
`tem has extended memory.
`NCache, a utility supplied with The
`
`Norton Utilities, and PC—Cache, a utility
`that comes packaged with PC Tools, both
`accept a wide range of cache sizes, such
`as 247K or 1,l42K. SmartDrive, however,
`only accepts cache sizes in 1MB incre-
`ments, such as 1,024-K or 2.l}48K. NCache
`
`also allows you to write-protect cached
`drives. This prevents programs from writ-
`ing to selected drives via DOS or BIOS.
`although NCache cannot prevent pro-
`grams from writing to disk if they access
`the hardware directly. Neither Smart-
`Drive nor PC-Cache supports this option.
`Finally, you can uninsta1lNCache and
`PC—Cache by using a command-line argu-
`ment, freeing up the memory that the
`utilities themselves are using. Smart-
`Drive offers no such option, but you can
`disable and reenable caching for one or
`more drives from the command line.
`
`While its performance and memory
`utilization are on equal ground with those
`of other
`third-party caching utilities,
`SmartDrive supports relatively few con-
`figuration options. While this may be per-
`fectly acceptable to the average user,
`hard-core power users may want to con-
`sider other products with which to fine
`tune their systems.
