Hi all.  After almost 4 solid years, I had a disk failure overnight (bad sectors). I have it configured under RAID-5 and a spare installed, so the Pegasus started rebuilding automatically as soon as it pulled the bad disk offline (now listed as staleconfig). Drive is still under warranty, So Seagate is sending a replacement IronWolf Pro 12TB today.

My question is what steps should I take when the new disk arrives? Best practices, if you will. Do I wait for the rebuild to complete, then pull the bad disk and set the new disk up as the new spare? 

Any insight is appreciated.
