I used PowerShell to run multiple instances of sg3_format

sg3_format just sends the format command to the drive. The formatting process is internal. It happens on the drive itself. You do not need to run multiple instances of the tool to complete format. The tool just keeps polling the drive for the status updates. You can disable this default behavior with the `-e`. If you would like to poll the status manually - use `sg_turs -p`.

Useful, thanks. If I'm doing multiple drives, I'll still loop it in PowerShell probably without that because who wants to manually poll the status of several dozen drives.

Received my 2 Samsung SSD , it has newer firmware NA53 , and newer date: 2019 09

sg_format failed with
Fixed format, current; Sense key: Illegal Request
Additional sense: Parameter list length error
MODE SELECT command: Illegal request sense key, apart from Invalid opcode

I had to use setblocksize
sudo ./setblocksize -b512 -t1200 /dev/sg1

Completed format of first SSD in about 20min, formatting the next SSD now.

It is nuts, someone brought 18 units at $505 each, the same seller listed $225 each on Tue.

I'm sure you can do similar in Bash to launch parallel instances of the format utility with a for each loop and substitute the loop counter into the device path.
I just commented on this in another thread yesterday... I do this using the GNU Parallel shell utility. It looks like:
user@ubuntu-server:~$ sudo parallel sg_format -v --format --size=512 /dev/sd{} ::: 0 1 2 3 4 5 6 7 8 9 10 11

I think you’re mis remembering the listing. That one was for the 7.68TB variants.

Anyone know how to check the remaining endurance on these? smartctl -a doesn’t show it.

Download HDSentinel. They make a Linux CLI version. It'll tell you. That's what I did for mine and they match the printouts I received with the drives.

Slightly off topic but can anyone confirm if this combo should work with these drives?

It *should* work for 4 drives. Just make sure you hook up power for each connected drive. You will certainly be limited to 6Gbps transfers (SAS2 HBA) to/from the drive. If it were me and I had budget, I'd purchase a SAS3 HBA instead.

Also nothing wrong with buying from Art of Server (member here on STH) and he does provide end user support. I would be remiss if I did not point out there are lower cost options than that HBA - however you'd likely have to x-flash the HBA and that might be outside of your comfort zone.

NB: I have seen instances using HGST SAS3 drives (SS200) of incrementing transfer error counts when connected to SAS 2 HBA's. I saw no signifcant impact to operations or 6Gbps performance as a result of the error counts. These drives are Samsung and I have no idea whether you will see this type of issue or not.

Thanks for the reply. I already have that HBA so planning to start with it and see if I can get the drives reformatted and test them out before investing in a SAS3 controller.

One more question, I’m new to SAS drives

Could I use this combo with these drives?

Figuring out with ICY-DOCK products are actually SAS can be obnoxious. SATA drives can be used with SAS controllers and enclosures. SAS drives can ONLY work with SAS enclosures and controllers.

So, I'm going with "No" since your specifying a SAS to 4x SATA breakout cable.


People who own this posted later in thread and I am wrong about this specific unit.
