KillDisk can be executed with some settings pre-defined when started from a command prompt with specific command line parameters.
KillDisk can be also launched in fully automated mode (batch mode) which requires no user interaction.
KillDisk execution behavior depends on either command line parameters (highest priority), settings configured in interactive mode and stored in the KILLDISK.INI file (lower priority), or default values (lowest priority).
To run Active@ KillDisk in command line mode, you open a command prompt screen. At the command prompt, start Active@ KillDisk for Windows by typing: KILLDISK.EXE -?
In Linux environment, type:
> KillDisk -?

|-passes=[1 - 99]||-p=||3||Number of times the write heads will pass over a disk area to overwrite data with User Defined Pattern. Valid for User Defined Method only|
|-verification=[1 - 100]||-v=||10||Set the amount of area the utility reads to verify that the actions performed by the write head comply with the chosen erase method (reading 10% of the area by default). Verification is a long process. Set the verification to the level that works for you better|
|-retryattempts=[1 - 99]||-ra=||2||Set the number of times that the utility will try to rewrite in the sector when the drive write head encounters an error|
|-eraseallhdds||-ea||Erase all detected disks|
|-excluderemovable||-xr||Exclude all removable disks from erasing, if –ea used|
|-excludefixed||-xf||Exclude all fixed disks from erasing, if –ea used|
|-excludedisk = [0,1,..63]||-xd=||Exclude disk from erasing, if –ea used|
|-erasehdd = [0,1,..63]||-eh=||Number in BIOS of the hard drive to be erased. First physical disk has a zero number. In Linux first disk usually named /dev/sda. In Windows Disk Manager first disk is usually named Disk 0. On older systems (DOS, Windows 9x) first disk is usually named 80h (obsolete syntax is still supported in the parameter)|
|-wipehdd = [0,1,..63]||-wh=||Wipe out unallocated space on the disk specified by BIOS number|
|-wipeallhdds||-wa||Wipe all detected disks|

|-stopaftererrors = [1,2..]||-er=||Stop erasing process after specific number of writing errors encountered|
|-clearlog||-cl||Use this parameter to clear the log file before recording new activity. When a drive is erased, a log file is kept. By default, new data is appended to this log for each erasing process. By default the log file is stored in the same folder where the software is located|
|-exportlog||-el||Export a log file as XML report|
|-logpath=["fullpath"]||-lp=||Path to save application log file. Can be either directory name or full file name. Use quotes if full path contains spaces|

|-inipath=["fullpath"]||-ip=||Path to the configuration file (KILLDISK.INI) for loading the advanced settings|
|-noconfirmation||-nc||Skip confirmation steps before erasing starts. By default, confirmation steps will appear in command line mode for each hard drive as follows: Are you sure?|
|-beep||-bp||Beep after erasing is complete|
|-test||If you are having difficulty with Active@ KillDisk, use this parameter to create a hardware information file to be sent to our technical support specialists|
|-batchmode||-bm||Execute in batch mode based on command line parameters and INI file settings (without user interaction, all operations being stored to log file)|
|-userpattern =["fullpath"]||-u||File to get user-defined pattern from. Applied to User Defined erase method. Each line in the file corresponds to the particular pass pattern|
|-shutdown||-sd||Save log file and shutdown PC after completion|
|-nostop||-ns||Prevent erase/wipe stop action|
|-help or -?||Display this list of parameters|
Parameters -test and -help must be used alone. They cannot be used with other parameters.
Commands –erasehdd, -eraseallhdds, -wipehdd and -wipeallhdds cannot be combined.
Type the command and parameters into the command prompt console screen at the prompt.
killdisk.exe -eh=80h -bm
> KillDisk -eh=80h -bm
In the example above, data on device 80h will be erased using the default method (US DoD 5220.22-M) without confirmation and returning to the command prompt screen when complete.
> killdisk.exe -eh=80h -nc -em=2
> KillDisk -eh=80h -nc -em=2
In this example, all data on the device 80h will be erased using US DoD 5220.22-M method without confirmation and showing a report at the end of the process.
In Linux environment, to detect and work with physical disks properly, Active@ KillDisk must be launched under SuperUser account, so, if you are not a SuperUser, you should type a prefix sudo, or su (for different linux versions) before each command.
After you have typed KillDisk and added command line parameters, press ENTER to complete the command and start the process.
Information on how drives have been erased is displayed on the screen when the operation has completed successfully. KillDisk execution behavior depends on either command line parameters (highest priority), settings configured in interactive mode and stored in the KILLDISK.INI file (lower priority), or default values (lowest priority).
This feature is intended for advanced users.
Batch mode allows KillDisk to be executed in fully automated mode without any user interaction. All events and errors (if any) will be placed in the log file.
This allows system administrators and technicians to automate erase/wipe tasks by creating scripts (*.CMD, *.BAT files) for different scenarios that can be executed later on in different environments.
To start KillDisk in batch mode, add the –bm (or -batchmode) command line parameter to the other parameters and execute KillDisk either from the command prompt, or by running a script.
Here is an example of batch mode execution with the wipe command:
> KillDisk -wa -bm -em=16
This will using Gutman's method and returning to the command prompt when complete, wipe all deleted data and unused clusters on all attached physical disks without any confirmations.
If –ns (-nostop) command line parameter is specified, no user interaction is possible after erase/wipe action started, so user cannot cancel the command being executed.
After execution, application returns exit codes to the operating system environment: 0 (zero) if all disks being erased successfully, 1 (one) if errors occurred or nothing erased/wiped, and 2 (two) if minor warnings occurred.
When you start KillDisk, change its settings (erase method, certificate options, etc…) and close the application, all current settings are saved to the KILLDISK.INI file in the location of the KillDisk executable. These settings will be used as default values the next time KillDisk is run.
KILLDISK.INI is a standard text file possessing sections, parameter names and values. All KillDisk settings are stored in the [General] section.
For parameter storage the syntax being used:
Here is an example of INI file:
[General] logging=0 showCert=true saveCert=false initDevice=true clearLog=false ignoreErrors=false skipConfirmation=true retryAtt=2 certPath=C:\\Program Files\\LSoft Technologies\\Active KillDisk\\ logPath=C:\\Program Files\\LSoft Technologies\\Active KillDisk\\ logName=killdisk.log …
When KillDisk is running in interactive mode, all these parameters can be configured from a settings dialog accessed by clicking the “Settings” toolbar button. They also can be changed manually by editing the KILLDISK.INI file in any text editor such as Notepad.

You can find a more detailed explanation of each parameter in Erase/Wipe parameters.
When you start KillDisk with or without command line parameters, its execution behavior depends on either command line settings (highest priority), settings configured in interactive mode and stored in the KILLDISK.INI file (lower priority), or default values (lowest priority).
Default value means that if the KILLDISK.INI file is absent, or exists but contains no required parameter, the pre-defined (default) value will be used.
