Preclear?

Featured Replies

Hi,

 

I am just starting out.. so excuse me if I am asking a stupid question....

 

When using unRAID Server 5.0-rc15a what command should I use to preclear a 3TB WD Red drive?

 

Should it be preclear_disk.sh /dev/sda?

 

or

 

Should it be preclear_disk.sh -A /dev/sda?

 

Also, What Default partition format should I have?

 

I have 3 TB WD Red drives and 3TB WD Green Drives, also some 2TB Seagates....

 

Thanks...

Does not make any difference with a 3TB drive, but if it makes you feel better, use the "-A" option. 

(The -A and -a options are silently ignored on any drive over 2.2TB)

 

You should set the "default" preference to MBR-alligned in the unRAID disk settings preferences.  Especially if a new server.  That setting will work for ALL disks except a 2TB WD EARS disk with a "jumper" added to electrically compensate for its brain-damaged firmware.

What do I do if I have a 2TB WD EARS disk with a "jumper"? Should I still set default to MBR-alligned?

 

ALso, How do i cancel a preclear once it is started?

Remove the jumper then Aligned.
