Cool, thanks.

Repost: Put in the wrong place first time... I am building a new array. I am using preclear_disk.sh 1.13 and unRAID 5 b14. I am starting out with a mix of Green and Black WD drives. All drives (except the parity which is a new 2TB Black) were in use on Windows systems before and none have ever had jumpers. I am running preclears on 4 drives at the moment. On two of the Greens I used preclear with -A. One is a WD15EARS, the other a WD20EARX. Below are the details of preclear -t for both after the successful preclear completed. My question/concern is that I have different Sector and I/O size for both. One shows 4k, the other 512b. Is something wrong here?
