Simple Preclear question

Recommended Posts

Unraid just runs and runs so I forget things (remember I just celebrated the 20th anniversary of my 52nd birthday)  I have 7 2TB disks in the server case.  Five are in the array, two are just sitting there powered on and spun down.


The problem:  I can't remember if I precleared them.  Is there any simple way to tell? When I look at them in unmenu the 2 disks in question have 1 partition on them (sdd and sdd1; and sde and sde1) with 2TB of space (2000.3G to be more accurate)

Thanks for the reply watskooo, Answers breed questions.


The command you recommended, at what position in the directory structure is that to be executed - root?


Is there a comprehensive preclear document that shows the options/commands?

If you execute it as


then it must reside in the current directory.


Typically, most people download it to their flash drive, so you would first have to change directory to /boot

and then invoke the command.

cd /boot

preclear_disk.sh -?
