Using the Awrite utility to write images

Updated 1 year ago by Bryan Jones


This document describes how to use the awrite.exe utility for writing images to, or creating images from compact flash cards used in Telos, Omnia, and Axia products.


Click HERE to download this utility and save it to a location on your computer.

The file you download is not an installer. The program runs directly from wherever you store the file on your computer.


The Awrite utility is compatible with all Windows operating systems from XP and newer.  When using on operating systems on Windows 7 and newer, you must run it with administrative rights.  To set the program to run with administrative privileges;

  1. Locate the file you downloaded.
  2. Right-click on the file and choose Properties.
  3. Choose the Compatibility tab
  4. Check the box that says “Run this program as an administrator” and then click OK.


We assume you have a writer appropriate to the media you are writing. While we mention Compact Flash here specifically, the program will work equally well for any removable media.
  1. Locate the card that you will use for this task and insert it into your writer. 

If your operating system pops up any messages telling you that you need to format the card, you may dismiss those messages. 


Run the program from the location you downloaded it to.

  1. Select the CompactFlash card from the drop-down list under where it says “Select physical drive:”
Note that awrite.exe will completely overwrite the entire contents of whatever drive you choose. Make sure you have selected the correct drive from the list. For this reason, we recommend leaving the "show fixed disks" box UNCHECKED.
  1. Click the Upload button to choose the image that you want to upload to the card. 

Use the upload dialog to browse to the image to write to the card. This image should have been provided to you already, and you should have saved it on this computer. Once you select the image, the writing process will start.

The program will display a green progress bar while writing, and once complete, it will show as though you had just launched the program. There will be no message indicating that the process has completed other than the progress bar will return to saying, "Idle."

If you receive an error message about the size not being correct, or that the image is possibly for a different card. It may be that you need to remove existing partitions from the card first. See the instructions below on how to use the Windows Disk Part utility for this.


Use the Download button to create an image of a compact flash card to save as a backup. To use this, click the Download button. When the dialog box appears, select a location to store the file and specify a filename. Once you click OK the program will begin to write the contents of the card to a file on your computer.


  1. Open a command prompt on your computer as an administrator.
    1. Locate your command prompt icon in Windows.
    2. Right-click and chose "Run as Administrator."

Your command prompt should show "Administrator:" like this.

  1. Type "diskpart" and press enter.

You should receive a message saying;

Microsoft DiskPart version 10.0.18362.1

Copyright (C) Microsoft Corporation.
On computer: MYWINDOWSPC50

  1. Type "list disk" as shown and press enter.

You will see all disks on your system listed here.

DISKPART> list disk

Disk ### Status Size Free Dyn Gpt
-------- ------------- ------- ------- --- ---
Disk 0 Online 100 GB 0 B
Disk 1 Online 3840 MB 3584 MB

  1. Select the disk. In this case, it's Disk 1. Type "select disk 1" and press enter.

Message will display saying "Disk 1 is now the selected disk."

Be VERY careful here. Disk 0 if the main hard drive of this computer. You must be careful not to select and wipe the wrong disk.
DISKPART> select disk 1

Disk 1 is now the selected disk.

WARNING - Next step is final
  1. Type "clean" and press enter.

DiskPart succeeded in cleaning the disk.


All partitions have now been removed from this disk and you may proceed with writing your image.
