• You initiate a rebuild on one failed drive
  • It shows “0%” or begins, then disappears entirely
  • BIOS or RAID utility now shows no virtual disk present
  • The rebuild process encountered unreadable blocks on another drive
  • The controller removed the array from access to prevent further corruption
  • RAID 6 parity logic failed to validate — now it doesn’t know what to trust
  • Don’t start over with a new array — that erases everything
  • Don’t reboot multiple times trying to make it show back up
  • Don’t assume the controller’s silence means total failure
  • Capture disk layout and logs using JeannieLite
  • Save controller memory state if possible
  • Freeze configuration until parity structure can be verified

A failed rebuild doesn’t mean all is lost — but your next move is critical. Let’s make sure it’s the right one.
