If you are going to remove a drive, test it and return it to the unit, that is best done with the unit powered off. If on the other hand are going to pull a drive and then replace it with another drive that is best done with the power on, the "hot-pull" + "hot-add" routine. If you hot pull a drive and immediately plug it back in, most often there will be not impact. When you hot pull a drive, the system will initially report the drive as dead, then report it as missing. At that point, is when the replacement should be inserted. The drive will be recognized, verified, tested, formatted and then resynched to the array. While it is best to add a drive with no partitions, it is not necessary, but you may get a message that the drive contains data. I always use Windows Disk Management to wipe the partitions on a drive that has been used before I add it to an array.
