Ok, so as per standard procedure (As far as i know), i had an issue with a Faulty Disk (sdc - SMART showing bad sectors), So powered off, removed old disk, Replaced with factory new, and fired up. Came up ok, Went into Raid Management, Selected Recover, and added the new Disk.
However Rebuild failed, ending up as "Clean, Degraded".
Replaced original sdc, and thats where my issues seem to have started...
I now seem to be completely missing the array. System recognises all Disks as present.
Array should be sda/b/c/d

I do have a backup, however it will take several days to re-build. Any way i can salvage this one??
