I’m at the part of running bad blocks but i don’t want it to run all four tests, 0xaa (10101010), 0x55 (01010101), 0xff (11111111) and 0x00 (00000000), just 0x55 and 0xaa.
From what i’ve found so far the below is to run one pattern, but is there a way to run two?
It goes to standard output. Since badblocks take hours, or even days, to run, you want to call it in a tmux session and redirect (>) or pipe (| tee) output to a file.
Have you tried invoking -t twice?
yes I’m following the Hard Drive Burn-in Testing | TrueNAS Community guide somewhat
but not no i don’t want to run the full test pattern twice, i want to run half of it. and was wonder if there was a way i can do it with one command
