[SOLVED] Preclearing Cache Drive

[fonzie]

I'm about to install a cache drive on my unRaid box.  So the first order of business is naturally to preclear it.  My hard drive that will be used as a cache is a Western Digital Caviar Green 500GB Model: WD5000AACS

Is it Advanced Format or not? Do I need to jumper it like the EARS?

 

I just want to make sure I preclear it correctly.

It is not AF so I will preclear it as a regular drive.

All drives can be pre-cleared as 4K-aligned/sector 64/"-A option" with no performance penalty except EARS with jumpers. Do not add jumpers to new EARS drives and format as 4K-aligned. There is no benefit to removing jumpers and reformatting existing EARS drives or non-AF-drives.
