Did I just brick my SAS drive?
I was trying to make a pool with the other 5 drives and this one kept giving errors. As a completer beginner I turned to gpt…
What can I do? Is that drive bricked for good?
Don’t clown on me, I understand my mistake in running shell scripts from Ai…
EMPTY DRIVES NO DATA
The initial error was:

Edit: sde and SDA are the same drive, name just changed for some reason And also I know it was 100% my fault and preventable 😞
**Edit: ** from LM22, output of sudo sg_format -vv /dev/sda
BIG EDIT:
For people that can help (btw, thx a lot), some more relevant info:
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
Thanks for all the help 😁



Thanks for the update, that’s helpful.
Confirming that the controller is a Broadcom / LSI SAS2308 and that it’s the same HBA that was used in the original TrueNAS system removes one major variable. It means the drive is now being tested under the same controller path it was previously attached to.
The device mapping you described is clear:
sda = known-good identical drive
sdb = the problematic drive
Running:
sudo sg_format --format --size=512 --fmtpinfo=0 --pfu=0 /dev/sdbas you did is the correct next step to normalize the drive’s format and protection settings.
A few general notes while this is in progress:
At this point it makes sense to pause any further investigation until the current sg_format has fully completed and the system has been power-cycled.
Once that’s done, the next step will be a direct comparison between sdb and the known-good sda using:
sudo sg_readcap -llaReported logical and physical sector sizes
Protection / PI status
As a general note going forward: on Linux / FreeBSD it’s safer to reference disks by persistent identifiers (e.g. /dev/disk/by-id/ or UUID (this is safer but not so direct human readable) on Linux or glabel on FreeBSD) rather than /dev/sdX, as device names can change across boots or hardware reordering as you have had some experience with now.
Post the results when you’re ready and the sg_format complete and we can continue from there.
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?
