I have created a RAID 5 with four disks and one of them has fallen off the array. All the HDs are new and the RAID is only two days old. I can no longer boot Windows 10 (so I can't use the Windows application) and I am trying to figure out how to rebuild my array through the EFI shell or the Legacy ROM. I don't see any options to select the drive that has fallen off and re attach it. Can someone point me in the right direction?
The RAID utility in the EFI shell is AMD RAID utility Rev. 126.96.36.199
