First, thank you for your response!
No, I do not mean "cannot" in the absolute sense. So, physically destroying the drives would be too extreme, particularly considering that I want to potentially sell the Linkstation Duo Pro, so it needs to be operational.
My concern with using the wiping software, is that it would take forever with the drives in the unit. Can I easily remove the drives without damaging the unit? If so, how? My hope would be to remove a drive from the unit, connect it to a computer as a local drive, then use the wiping software on the local drive, replace the drive, and use the linkstation to re-format it to whatever format the linkstation prefers. I wonder if there is some kind of documented procedure for this.
Also, can you recommend any free wiping software for Windows?
Thank you!
