About Inoperable Units

Units become inoperable when there are no longer enough drives in the unit for it to function. For example, a RAID 5 unit created from four drives becomes degraded if one drive fails or is removed, but becomes inoperable if two drives fail or are removed. A RAID 6 unit created from five drives becomes degraded if one or two drives is removed, but becomes inoperable if three drives fail or are removed.

Data on an inoperable unit cannot be accessed unless the missing drives are reconnected.

If you have data on a unit that is currently “inoperable,” contact technical support. A form is available on the web at
