Netgear ReadyNAS NV+V2 - Secure Erase Locked Hard Drives??
Hi, This evening I did a secure erase on the readynas I have and after the 7 hour wait, the hard drives no longer work as if they have been locked in some way. Prior to doing the secure erase I h...
Did the secure erase complete? Or did you interrupt it? It takes a very long time, and it should have unlocked the disks when it was done. If you interrupted it, you could try running it again to completion.
You can unlock them using hdparm if you can boot the NAS in tech support mode. Instructions on on pages 24-25 here: http://www.downloads.netgear.com/files/GDC/RND2110/ReadyNAS_Duov2_NV+v2_HW_en_23-Mar-12.pdf
Then connect to the NAS using telnet. The login is root, the password is infr8ntdebug
From there you need to run a utility called hdparm. Hopefully it will be available in tech support mode.
# hdparm --security-unlock NETGEAR /dev/sda # hdparm --security-disable NETGEAR /dev/sda
Repeat for the other three disks (sdb, sdc, sdd).
hdparm is also available for Windows, so you could try installing it, and connecting the disks to a PC with SATA or a USB adapter/dock. If Windows prompts for a password for the drive, enter NETGEAR (all caps). The path to the drives will be different with Windows. Also you should run hdparm as administrator.
The Nas said it had finished erasing on the display but I couldnt do anything else with it apart from switch it off at the mains.
I then switched it back on again and now the only thing that displays is a "booting" screen on the display.
