This hard drive is becoming a pain to get working it has no protection and I have formatted the Drive using sudo sg_format --format --size=4096 /dev/sdh and also 512 but i am having no luck I have decided to format it again with size=4096.

Any one got experience on this drive and am I doing something wrong
Update: If I use unraid to format I get an error saying IO error on further investigation I found it had a non standard block size. When I low level the HDD and set the correct block size it still won't take to the drive. That's using the included sg_format command in unraid.

Update as I can't reply

Attach Diagnostics ZIP to your NEXT post in this thread.

You shouldn't be using the command line. What exactly happens when you use the Unraid webUI to format the disk?

This is the problem; you need to reformat the disk with a 512B sector size.

I have done a full format low level and fixed the sector size problem but i am still getting IO errors

I have low levelled formatted the drive a few times but I cant get it to work. I have done 4096 blocks and 512 unraid can see the drive now. I have the zip below.

Drive is still not mountable but can been seen.

Commands I used to get it working
sg_format --format --size=512 /dev/sg7
sudo ./setblocksize -b512 -t1440 /dev/sg7 <- This one actually corrected the block size

More info

SAS drives can come with write/sed protection sometimes, see this in case it helps: https://forums.unraid.net/topic/110835-help-with-a-sas-drive/

After trying everything including removing any protection on it, I have found out that the firmware on the drive was the problem (7FA6) as it only works with a write and verify command, I will be getting a different SAS drive with a different firmware.

Thanks for the help
