Hello the.mknabster,   You don't have to format the drive before installing. You can do this while in the controller BIOS: Insert the drive, set it as Hot Spare. If it detects data on the drive it will show as Foreign. Clear the foreign then set it as Hot Spare.
Hi all, i currently run a RAID 10 array in my Poweredge T420, and i would like to future proof my backup drives in the case of a drive failure, but i wasn't sure if my replacement drives need to be in a certain format for the swap to take place. I noticed there was a way to format drives as hot spares, is this what a replacement drive would need to be formatted as before it was popped in for the PERC to fail over a bad disks data from the backup, or can it be just as the drive is and the PERC will take care of everything? Thanks
