Jacob W Posted April 20, 2022 Share Posted April 20, 2022 Hi, I am somewhat a novice to UnRaid. I have been running a server for a few years but for basic stuff. i bought a new server (Dell R810) and picked up HGST 900gb SAS drives for it. I am having the hardest time getting them into the array. No matter what i do i get an error "Unmountable: Unsupported Partition layout". I have googled and searched here and nothing seems to work. So far i have changed them from 520 to 512 block size. I have attempted to allow unraid to format them. I have formatted them with UD on destructive mode. attempts to pre-clear fail. i have used the sfdisk command to see if that works. I am basically trying everything. I have attached my diagnostics info. the only thing i can see is that the disks still list a format of DOS with sfdisk instead of GPT or MBR. Any help would be amazing. jlbeast-diagnostics-20220420-1106.zip Quote Link to comment
JorgeB Posted April 20, 2022 Share Posted April 20, 2022 Often SAS drives come with some kind of format or encryption protection, see below if any of these help: https://forums.unraid.net/topic/93432-parity-disk-read-errors/?do=findComment&comment=864078 https://forums.unraid.net/topic/110835-help-with-a-sas-drive/ Quote Link to comment
Jacob W Posted April 20, 2022 Author Share Posted April 20, 2022 Sorry i forgot all the steps i completed. I did remove the protection with that post already. I am also running an H200 controller in IT mode to pass all 6 drives through. Quote Link to comment
JorgeB Posted April 20, 2022 Share Posted April 20, 2022 There appears to still be something preventing any writes to the devices. Quote Link to comment
Jacob W Posted April 20, 2022 Author Share Posted April 20, 2022 Ok. Grrr. Looking at the posts that you linked and running through them again. I will update when i complete them Quote Link to comment
Jacob W Posted April 21, 2022 Author Share Posted April 21, 2022 (edited) After most of the day trying different commands, i am seeing that there is no protection on the drives. However they still won't format. Diagnostics and screenshot attached. Any ideas? jlbeast-diagnostics-20220420-2143.zip Edited April 21, 2022 by Jacob W Quote Link to comment
