October 18, 20169 yr Good Morning, I recently had a drive error (Red X). I wasn't sure if the drive had actually failed, but to be safe, I installed a fresh drive and successfully rebuilt the new disk. Everything went well. Today, I decided to re-install the old disk to run an extended SMART test. It appears the drive is bad. Can I remove the bad drive from the array without rebuilding parity? Thanks.

Are you saying that you assigned the bad drive to a new slot in the parity array? Or you just plugged it in without assigning it to an array slot so you could test it? If it is not assigned to an array slot it has no effect on parity.
October 18, 20169 yr If you added the bad drive to the array, parity was modified to include it, so yes, parity has to be modified or rebuilt to remove it. See the Shrink array wiki page.
