Failed to do secure erase on disk

[darrynhatfield]

Hi Guys,

I am trying to use my TNAS F4-424 to do a secure erase on some old disks. I have a disk with no partitions that I tried to erase and the process starts ands then 5 secs later it says "Failed to do secure erase on disk HDD3.
I have also tried to adding the disk to it's own storage pool but it would run until I deleted the pool. Then the same issue.
I have a bunch of old disks from work that I want to erase and the NAS would be a great tool to use for this purpose.
Can anyone suggest what is going on or if there are any logs that I could look at to see what is happening?
NOTE: I am running TOS 5.1.145-00320

Is this the only disc with problems?
You can log into a terminal and check the relevant kernel logs with the dmesg command. It may be able to log relevant exceptions.

For some reasons, your drive may be at "frozen" status, remove and insert the drive, and try again.

I checked and it wasn't frozen. I managed to find a url that showed me how to use hdparm to perform the secure erase from the terminal. FYI https://grok.lsu.edu/article.aspx?articleid=16716
