Secure erase of hard drives
It would be very useful if QTOS supported securely erasing hard drives by writing random data over it a specified (i.e. 0-10) number of times.

until then.... what i normally do if i wanted to really do a clean wipe. I format via QNAP. when done, i pull out all the hdds then use my HDD dock station which is connected to my desktop. I can then run privazer and wipe it that way via connected usb device selection
hdd docks are really useful (for my own use i use it for diagnosing issues with hdd using other third party apps which can only be run from desktop pc, or just a quick way to access a HDD), i recommend getting one

Re: Secure erase of hard drives

Re: Secure erase of hard drives
Trouble is that secure erasing HDDs (or SSDs) is hardly possible if the units are broken or run-out. SSD might block writing completely once the number of allowed writes is hit, too. For storage blocks going to re-usage or sales, a secure erase is better done off the NAS, because commonly the NAS has to return to service ASAP.

Re: Secure erase of hard drives
4.3.4 added a feature for securely erasing hard drives.alxrmrs wrote:It would be very useful if QTOS supported securely erasing hard drives by writing random data over it a specified (i.e. 0-10) number of times.
Secure Erase
Secure erase permanently deletes all data on a disk, ensuring that the data is unrecoverable. Using secure erase on an SSD also restores the disk's performance to its original factory state.
To begin, select a free disk, and then select "Action" > "Secure Erase". In the Secure Erase Wizard, follow the instructions to specify other disks to erase and the erase method.
If all disks in the NAS have been selected for a secure erase, a full NAS system re-initialization is required.
*Note: During the secure erase process, do not unplug any disks, or power off or restart the NAS. This ensures disks are fully erased and can be used again afterwards.

Re: Secure erase of hard drives
Awesome, thanks for the feature QNAP! Hopefully this will work on my failing drives so I can throw it out. I'll find out this week.

Re: Secure erase of hard drives
If the SMART information says "Warning" secure erase is not available under actions. Is there a way to override this?

Re: Secure erase of hard drives
if the drives are failing and are just tossed out .. why go through a secure erase? .. a nail through the top cover works faster and is more secure

Re: Secure erase of hard drives
The Secure Erase is available for "free" disks only - disks not used in a storage pool or holding a legacy volume. A control the "Free" a disk (remove from a redundant RAID) to secure erase and replace for rebuilding the RAID does not exist unfortunately. Please support the "Free" disk control addition feature request by filing tickets on https://helpdesk.qnap.com/ mentioning MantisBT 28413.alxrmrs wrote:If the SMART information says "Warning" secure erase is not available under actions.

Re: Secure erase of hard drives
Is it possible to set the disk as free even though the SMART status is warning? Under SMART it does say that the disk should be operating properly.

Re: Secure erase of hard drives
I would like to know if this is possible too. I have a drive that is working, but it listed as "warning." I'm replacing it (since it's less that 30 days old) but I'd like to wipe it before I send it back. Any way to do this in the NAS?alxrmrs wrote:Is it possible to set the disk as free even though the SMART status is warning? Under SMART it does say that the disk should be operating properly.

Did you get the solution for this? I am in the same boat. have to return the hard disk after wiping all the data.oldWindowsGuy wrote: ↑Tue Oct 09, 2018 12:36 pmI would like to know if this is possible too.

Re: Secure erase of hard drives
sadly the "safe erase" option is not available for external drives :/
