Automated NDW “Network HDD data Wiping” is a complete solution that has operating system and server software which is installed on a computer. Server is connected to a network switch and several PXE boot enabled workstations are attached to the network. As soon as the workstation is powered on, it boots off the network via the server and begins wiping all the attached hard disk drives. Once all the hard drives have been wiped, a mini self-adhesive data destruction certificate is printed and data related to each hard disk will is stored in the central server’s database, Data can be accessed using web GUI interface.
(Self-adhesive mini data destruction certificate that is printed automatically after each HDD data wipe that you can attach to HDD).
You can see above label it has following codes.
PCC: Power Cycle Counts, lower the number better the hard drive.
REC: Reallocated Event Count (Large number of REC meaning more tear and wear)
CPS: Current Pending Sector “This is related to bad sectors, 0 is better any other figure is bad.
OU: Offline Un-correctable “Offline sectors that cannot be corrected or reallocated”
(See the network diagram below).
Prior to installation make sure you have a server pc ready for installation, please check the pre-requisite for the server in previous section.
In order to begin installation, download the latest copy of software in ISO format following location.

Access the GUI at following URL. http://192.168.1.253
Below you can see the main menu of the automated data wiping system.
You can now start a new network data wiping by clicking “START WIPING” button.
Once you click “START NETWORK WIPING” button you will see following screen. (Screen shot on the next page)
Please fill the require information and click Save.
Note: Please fill all fields otherwise you may have problems with wiping.
Once you have completed all the selections, click Save. Following message will appear.
Now you can close this window and begin data wiping.
In order to begin actual data wiping, please ensure all your workstations have network cards and pxe boot is enabled. Also ensure there are no usb storage devices connected to the workstation, make sure all the hard disk drives are connected either using SATA, ATA or external RAIDS arrays.
Now boot the workstations.
You may see following screen during the boot process.
After above screen display you will see following warning messages.
Next blue screen will begin wiping the data automatically from all attached hard disk drives.
Once the data wiping has finished execution, success message will appear and a barcode label will be automatically printed for each hard disk drive and the workstation will shut down automatically.
Once you see the success message or you find the system shutdown at this point you can remove the existing hard and install the next batch to be wiped.
You can monitor the status of data wiping using the server GUI interface.
To view the status of the data wiping please click the customer portal button on the Home page of management console.
Next screen may looks like this:
In the above screenshot you have 3 options. From date, to date and customer ID or name. If you have several customer they will automatically appear on the list. Choose the date range and customer that you want to view the status and click submit.
The next page will show you detailed information about data wiping progress (see below screenshot).
The page above shows customer name, hdd manufacturer, model, serial number, size, firmware, method used to wipe, date wiped, start and end time, workstation number, results and finally the last column allows you to print individual certificate for each Hard Disk Drive.
Note: the last column will let you print individual data erasure certificate for each storage device.
Important note: At the bottom of each page there is button to export the certificate to MS Excel format.
Now let’s view the individual certificate for each hard disk drive by clicking the print button of each hard disk drive column.
You may have noticed above there are few barcodes, the first barcode contains customer name, 2nd barcode contains customer name and hdd serial number, 3rd barcode which is a data matrix barcode contains all the information regarding hdd, method code contains the method used to wipe the hdd and spindle code contains model and serial number of the hdd.
These barcodes ensures that the certificate is authentic and is not tampered. You can read the data from barcodes by using standard 2d and 3d barcode scanners.
Lets go back a step to the previous page.
As explained previously at the bottom of every page there is a button to export the report to Excel. In this case it is called Imran-Report-Excel.
Clicking this button will open this report in Excel, you can use excel file to email to customer or create PDFs.
