The next stage on my journey to a new NAS is to pass on my old Synology NAS to its new owner. Before I do so, I want to (securely) wipe its disk drives with a single pass, but there don't appear to tools provided to carry out the task. I guess I could just use my Mac's Disk Utility to wipe the entire 9TB, but is there a way I can do this from DSM so it's not tying up my Mac? I've tried searching Synology's website and their forum, but found nothing useful so far that doesn't involve removing drives from the encolsure.

Perhaps I could do it via some terminal commands on the NAS?
 
only real secure way would be to pull each drive, connect it to a machine and secure wipe.

as far as i know there isnt (or at least wasnt) any secure wipe options.

you could destroy the array and hope that the new owner rebuilds and chucks a load of data onto it.
 
Wiping via Disk Utility's Zero Out Data function directly without removing the drives would achieve the same thing?
 
My synology DS212J has a securely delete drive option, buried somewhere in the storage management options. What version do you have?
 
I'm on 5.2 and it's in there, so not sure if an additional feature.
 
I use military spec disk wiper but it does take ages though. None of my recovery software gets anything back.
I have recovered data from wiped NAS drives before but they weren't in an array.

If its sensitive I'd connect each drive to a pc in a dock and wipe.
Or use a ringer but that will completely kill the drive so you might as well blow torch it.
