Abstract
A system (and method) for a recovery of data from a lost sector in a storage system, which includes a set of readable and lost sectors in a plurality of disks in the storage system, includes identifying a lost sector of at least one disk of the storage system, determining whether the data from the lost sector is capable of being recovered, and, if the data from the lost sector is capable of being recovered, generating a recovery formula for the lost sector and recovering the data from the lost sector based on the recovery formula.
