I wonder if I can "fix" my RAID 5 system with a one disk at a time approach. Pull a drive. Use Linux to zero the drive. Use Windows to build the requisite NTFS partition to prevent complaints. Run the update. Rezero the partition information. And finally reinstall the drive in the RAID and let the RAID rebuild. Lather, rinse, repeat three more times for the other disks.
Of course, methinks I'll take a complete disk image backup of the RAID just in case.
Any thoughts regarding this approach? Is there anything simpler that can be done?
