Losing Volume on Raid 0 #24221687

I can confirm that the disk unlock performed by mdgm worked. My NAS systems are syncing as I type this.

To summarise for anyone looking at this thread with same issue. Without physically trying it myself, it would appear that once the SSH add-on is installed, and you’ve logged in to your NAS using something like mobaXterm or putty (your NAS username is “root” and the password is your normal admin password) the commands you need are:

hdparm --security-unlock NETGEAR /dev/sda
hdparm --security-disable NETGEAR /dev/sda

hdparm --security-unlock NETGEAR /dev/sdb
hdparm --security-disable NETGEAR /dev/sdb

hdparm --security-unlock NETGEAR /dev/sdc
hdparm --security-disable NETGEAR /dev/sdc

hdparm --security-unlock NETGEAR /dev/sdd
hdparm --security-disable NETGEAR /dev/sdd

with the a, b, c, d at the end representing each of the physical disks of your NAS.

Well this is my understanding of it. If this isn’t fully correct, then feel free to correct me mdgm.

To mdgm, thanks you for your help with this issue. You’re a life saver. I’d also like to thank vandermerwe for his input.

Thanks again guys.
