Zusammenfassung:One aspect of the invention is a method for providing protection from data loss on a storage device. An example of the method includes designating a number n, and identifying a plurality of groups of strips on the storage device, wherein a number of strips in a plurality of the groups is equal to the number n. This example also includes reserving a respective parity protection strip on the storage device, for a plurality of the groups of strips identified on the storage device. This example further includes calculating a parity value for a plurality of parity protection strips on the storage device, wherein each calculated parity value is a function of information stored in each of the strips in the corresponding group of strips. This example additionally includes storing the calculated parity protection strip parity values, in corresponding parity protection strips.
