How the solution works.

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).
