6 Avira NTFS4DOS Personal Avira GmbH

Product information
3.1 Method
There are two ways to access NTFS drives from DOS. The NATIVE and the CAPTIVE
method. While the suppliers of other solutions employ the CAPTIVE method, Avira
NTFS4DOS consistently uses the NATIVE method.
This gives you three main advantages:
•Absolutely reliable read and write access
Avira NTFS4DOS communicates with the file system directly and supports native
NTFS. This ensures that the read and particularly write access to the data carrier is
absolutely reliable.
•High performance
As Avira NTFS4DOS communicates directly with the file system and does not need
to emulate all functions, it distinguishes itself through a clearly higher performance
compared to the other solutions that use the CAPTIVE method.
•No infringement of the Microsoft license terms
Avira NTFS4DOS does not save any parts of Windows on the boot diskette.
Therefore, it does not affect Microsoft license terms in any way.
Avira GmbH Avira NTFS4DOS Personal 7

Working with Avira NTFS4DOS
5Working with Avira NTFS4DOS
Here you will find information on:
•see Chapter: Configure boot device
•see Chapter: Command line parameters
•see Chapter: Saving disk space
•see Chapter: Maximize I/O speed
•see Chapter: Avira NTFS4DOS on Windows 98 and Windows ME
5.1 Configure the boot device
Editing the file config.sys
You can edit the existing file config.sys. For example, you can activate other device drivers
for the CD-ROM drive or a Microsoft network client.
For further details on editing the file config.sys please refer to your DOS documentation.
Editing the file autoexec.bat
You can edit the existing file autoexec.bat. For example, you can start anti-virus or
imaging software.
For further details on editing the file autoexec.bat please refer to your DOS
documentation.
Integrating additional software
If you want to copy additional software, such as Volkov Commander, to the boot device,
please note that this software is packed and extracted on drive X: after the boot device
starts. Configure the files config.sys and autoexec.bat accordingly.
When integrating additional software, please note that it should not exceed 200
kilobytes if you want to work with a boot floppy disk.

Working with Avira NTFS4DOS
5.2 Command line parameters
You can start Avira NTFS4DOS at any time via the command line.
Avira NTFS4DOS supports the following command line parameters:
Parameter Description
/lX Sets the letter of the first used drive. For example, lC means that the first
partition detected contains the letter C.
/rX Sets the RAM disk size. For example, r4 means that Avira NTFS4DOS was
designed with a 4MB RAM disk.
/? Displays a help screen.
When starting, Avira NTFS4DOS automatically loads a new shell, or a program run as a
shell. If no shell is specified, Avira NTFS4DOS uses the default shell (command.com).
After completing work with Avira NTFS4DOS, you can stop the shell and thus also
release the memory used by NTFS4DOS again.
Examples for calling Avira NTFS4DOS
Example 1
NTFS4DOS /lF /r8 command.com /C mybatch.bat
fThis command starts Avira NTFS4DOS to connect the detected NTFS partitions,
starting from the drive letter F, and creates an 8 MB RAM disk. The RAM disk
contains the first free drive letter for every connected NTFS drive.
fThe file mybatch.bat is executed in a new shell.
fAfter executing the file mybatch.bat, Avira NTFS4DOS stops automatically, because
the shell parameter /C was called. Please refer to the DOS operating system
documentation for information on all possible shell parameters.
Example 2
NTFS4DOS F:\AntiVir\avcmd.exe
fThis command starts Avira NTFS4DOS to connect to all NTFS partitions found,
starting with the first available drive letter, without creating a RAM disk.
fThe anti-virus scanner is run in a new shell.
fWhen this ends, Avira NTFS4DOS turns off again.
Avira GmbH Avira NTFS4DOS Personal 13

Working with Avira NTFS4DOS
Example 3
NTFS4DOS /lE /r4 command.com /K f:\vc\vc.com
fThis command starts Avira NTFS4DOS to connect detected NTFS partitions,
starting from drive letter E, and creates a 4MB RAM disk. The RAM disk contains the
first free drive letters for the connected NTFS drives.
fThe Volkov Commander is run in a new shell.
fAfter terminating the Volkov Commander, Avira NTFS4DOS stays loaded until the
shell is closed with the exit command.
5.3 Saving disk space
In order to save disk space, you can start Avira NTFS4DOS from config.sys. This is useful
especially when the memory is too low for running a utility program.
Example of a config.sys file that loads Avira NTFS4DOS and offers maximum space. This
file, based on MS-DOS 6.22, has approx. 440 KB free on the DOS memory after booting.
SWITCHES=/F
DOS=HIGH,UMB
DEVICEHIGH=A:\HIMEM.SYS /NUMHANDLES=128 /TESTMEM:OFF /Q
DEVICEHIGH=A:\UMBPCI.SYS
BUFFERS=11,0
FILES=60
LASTDRIVE=Z
FCBS=1,0
STACKS=0,0
SET CMDLINE=
INSTALLHIGH=A:\ntfs4dos.exe /r4 /lC A:\command.com /K
A:\autoexec.bat /E:1280 /P
14 Avira NTFS4DOS Personal Avira GmbH

Working with Avira NTFS4DOS
5.4 Maximize I/O speed
With the ntaccess.lib access technology, Avira NTFS4DOS offers maximum performance.
However, disk access on DOS is usually slow as it does not use UDMA. The powerful
UDMA mode for accessing the IDE drive is not implemented in many BIOS versions, but
only the much slower PIO mode. The maximum transfer rate of the hard disk in this case
is approx. 8 MB/s, which in practice results in a random access data transfer rate of
about 1MB/s.
Modern hard disks, on the other hand, reach a transfer rate of 10 MB/s and more if
operated in the faster UDMA mode. However, this requires a special driver.
You can insert this UDMA driver in config.sys:
devicehigh=udma.sys
The UDMA driver was developed by Latschezar Georgiev. For more details and the
current driver version, please refer to the dedicated website.
Avira NTFS4DOS uses an internal cache memory of 2 MB to additionally speed up data
access.
5.5 Avira NTFS4DOS on Windows 98 and Windows ME
As a DOS program, Avira NTFS4DOS also runs on Windows 98 and Windows ME in the
DOS box. Therefore, you can use, for example, an anti-virus program installed on
Windows 98 to scan NTFS drives for viruses.
However, Avira NTFS4DOS must not be started in the file autoexec.bat if installed on
Windows 98/ME. It should always start in a DOS box because when opening the DOS
box the connected NTFS drives are also accessible.
On Windows NT, Windows 2000 and Windows XP you cannot use Avira
NTFS4DOS in a DOS box because these operating systems do not support
direct hardware access.

6.1 Defragment NTFS drives with DEFRAG
The offline file defragmentation is the best method for defragmenting all files of an
NTFS drive. It guarantees that no file is in use during defragmentation. The process does
not remove any files, it only defragments them.
The defragmentation with DFRGNTFS can increase the speed of Windows by 100% or
more. The regular use of DFRGNTFS keeps the defragmentation time short and your
computer runs at a high speed.
In the case of highly fragmented and very large partitions, the first use of
DFRGNTFS may last up to 2 hours.
Function key commands:
Function key Command
F5 Change the defragmentation level
F6 Show partitions
F9 Restart computer
F10 Shut down computer
This is how you defragment a partition
fStart Avira NTFS4DOS by booting with the boot device you created in the Wizard.
fSelect the option Defragment NTFS.
DEFRAGNTFS starts. The hard drives are scanned for existing NTFS partitions
and a list of the results is displayed.
fPress F5 to select the required defragmentation level.
fSelect the required defragmentation level.
–0 corresponds to a fast and less intensive defragmentation.
–1 corresponds to the recommended default defragmentation.
–2 corresponds to a full defragmentation.
fType the letter of the drive to be defragmented.
Do not interrupt a defragmentation process because this may lead to loss of
data being defragmented.
Defragmentation starts. After the drive is completely defragmented, the menu is
displayed again.

Tools
6.2 Check and repair hard disk
CHKDSK and CHKDSKG are tools that enable the start of the service program used by
Windows autochk.exe. It searches for the file autochk.exe on the entire hard disk. If the
file is not found, the hard disk cannot be scanned.
If the file autochk.exe could not be found, proceed as follows:
fOn a local partition, create an arbitrary directory (for example, AUTOCHK).
fIn that directory, create a sub-directory named SYSTEM32.
fCopy the file autochk.exe from another Windows installation to the sub-directory you
created.
fRestart CHKDSK or CHKDSKG.
Differences between CHKDSK and CHKDSKG
While CHKDSK is a clean command line tool, which automatically checks and repairs all
found and identified partitions, CHKDSKG is a GUI tool for the less experienced user.
With CHKDSKG you can perform scanning or scanning with repair.
CHKDSKG
Function key commands:
Function key Command
F6 Show partitions
F9 Restart computer
F10 Shut down computer
This is how you check the hard drive with the Check Disk GUI Tool (CHKDSKG)
fStart Avira NTFS4DOS by booting with the boot device you created in the Wizard.
fSelect the option Check Disk GUI Utility.
CHKDSKNT GUI starts.
fType the letter of the drive to be scanned. You can also use *to scan all drives.
You are asked if you want to run Check Disk in read-only mode.
fSpecify whether Check Disk should run in read-only mode.
–Yes: Drives are only scanned, not repaired.
–No: Drives are scanned and, if possible, repaired.
The scanning of the data carrier starts. When the scanning is complete, the
menu reappears.
