Got my HDDs delivered. How can I test them all before putting real data on them? (alien.top)

I got my 10x HDDs delivered from ServerPartDeals, they're Dell branded Exos drives, Seller Refurbished

​

I know one of the first things I'm supposed to do is make sure they're configured to run at 4K, not 512, so I'll be checking that.

​

I'll also plug them all into a HDD dock and read the SMART data off them.

​

Afterwards, I remember reading a guide (here I believe) about how to test all the drives. There was a command line tool to check the drive for errors.

Does anyone know what I'm talking about? I remember I had to run a plugin on the computer to make sure I could run multiple instances of it.

​

Alternately, I intend to spin up a TrueNAS instance for this, does TrueNAS have any built in tool to fully check the drives before I create any pools?

when I get new hdds, i open a tmux instance with one pane per hdd, then i do:

  • smartctl -t short /dev/sdX
  • smartctl -t conveyance /dev/sdX
  • badblocks -b 4096 -ws /dev/sdX
  • smartctl -t long /dev/sdX

And if it passes all those, then I put them into a zpool.

edit: for bigger drives, you might need to increase the block size for badblocks, 65535 for example.
