Have you removed any protection.


Xiv drives previous post have protection but doesnt seem to indicate from sgformat


Formatted with type 2 protection 8 bytes of protection information per logical block


Are you able to post smart report for the drive?

I think I have found the problem the ST4000NM0043 is a SED drive (self encrypted drive)

and I dont think unraid supports it.

Found this online


I also had 48 Seagate SED drives that were locked and I use the SeaTools for windows with the PSID number on the drive and boom they are unlocked and we can erase them and re-purpose them no problem.


You can install seatools on unraid details in this thread.

the problem was TCG protection once I removed it withe the tools in Seachest they are god to go.


the command i used was  SeaChest_Security_x86_64-linux-gnu -d /dev/sgXX --revertSP --confirm this-will-erase-data --psid "your psid writen on the lable"


if you want to check if protection is active on not run SeaChest_Security_x86_64-linux-gnu -d /dev/sgXX -i


thank you all for the help
