Great News!
Format completed and now the drive is viewable in “Disks” (however it is still unknown compared to the other one, it might just need a normal format.
The code for the comparison returns invalid option, I assumed you need just -l comparison:
sudo sg_readcap -l /dev/sdb and sudo sg_readcap -l /dev/sda
One question I have is: what do you mean by powercycle? Is that another command to run on the problematic drive? If you mean turn off the pc and turn it back on, I will do that right now, just after the drive has completed formatting.
After PowerCycle (turned pc off and on)
sudo sg_readcap -l /dev/sdb and sudo sg_readcap -l /dev/sda
Would the next step be formatting of some kind?
Thanks for the continued support! ❤
I’ve attached an identical Segate SAS drive from the server.
To confirm, it is the same LSI card that was in the TrueNAS server. I pulled it out of the server and put it into the trouble shooting machine, where I run the commands.
It is this one: 01:00.0 Serial Attached SCSI controller [0107]: Broadcom / LSI SAS2308 PCI-Express Fusion-MPT SAS-2 [1000:0087] (rev 05)
I did not see your other reply lol, I will also try this command that you recommended:
sudo sg_format –format –size=512 –fmtpinfo=0 –pfu=0 /dev/sdb
Also, the sg_format ran for less than 5 minutes, very quick. However, if I can recall, it did say it was completed.
**Note: ** “Bricked Drive” turned to sdb
Identical working drive installed as sda
Here is the dmesg -T > dmesg-full.txt with the identical drive
Here is the code from: (with the output for each drive, separately)
sudo lspci -nnkvv
sudo lsblk -o NAME,MODEL,SIZE,PHY-SeC,LOG-SeC,ROTA
sudo fdisk -l /dev/sdX
sudo sg_inq -vv /dev/sdX
sudo sg_readcap -ll /dev/sdX
sudo sg_modes -a /dev/sdX
sudo sg_vpd -a /dev/sdX
Thanks again for all the help, I await your reply. :)
I will let you know the results of (sudo sg_format –format –size=512 –fmtpinfo=0 –pfu=0 /dev/sdb), as soon as it’s done.
Thank you for helping! Like I said I’m a complete beginner with little knowledge of all this, means a lot 🤗
just so you know I connected the drive to my dell pc, so its just the one broken drive not all 6.
Exact drive model: SEAGATE ST4000NM0023 XMGG
HBA model and firmware: lspci | grep -i raid 00:17.0 RAID bus controller: Intel Corporation SATA Controller [RAID mode] Its an LSI card Bought it here
Kernel version / distro: I was using Truenas when I formatted it. Now trouble shooting on other PC got (6.8.0-38-generic), Linux Mint 22
Whether the controller supports DIF/DIX (T10 PI): output of lspci -vv
Whether other identical drives still work in the same slot/cable: yes all the other 5 drives worked when i set up a RAIDZ2 and a couple of them are exact same model of HDD
COMMANDS This is what I got for each command: verbatim output from
Edit: from LM22, output of sudo sg_format -vv /dev/sda
I really appreciate your knowledge and help 🙂
Let me know if anything else is needed





Oh my what a ride! I got everything up and running in a RAIDZ2 with the 6 x 4TB drives! (soon i will add another 4 x 1tb in an icy dock as a separate vdev)
Everything works now with no errors! 🥳
I could not have fixed this without your help. You are a lifesaver and probably saved this drive from the landfill lol. I honestly can’t thank you enough for your continuous support throughout many days!
You are the light that shows that there are still good people on the internet that want to help, and not just lurkers that laugh and move on and treat everything as content instead of a person on the other side sharing something that is important to them.
In my case I was in need of help, and like one comment put it: Out of the 50 messages of ridicule, one person will actually go out of their way and help.
I learned soo much and a good lesson too!
Thanks again for your help, and I will remember this interaction for the rest of my self-hosting journey! I’m serious.
Keep helping others and sharing your knowledge. I will pay this kind gesture forward in the new year, and help others more with the things that I know. 🫡
(Please don’t delete this convo, might help someone in the future)
Thanks again and Happy Holidays!
I wish you all the best in the New Year! 🤗 🎉
