    It is counted from the left.  You can power down the system, remove the disk, and confirm it by checking the serial number.

     

    Generally I recommend hot insertion for replacement, but power-down insertion also works.

     

    I suggest replacing it with either a WD Red drive or a Seagate Ironwolf drive.  Generally NAS-purposed drives work better than desktop drives with RAID, and a lot of folks here (and elsewhere) have had problems with the ST3000DM001 drive in particular.
