Summary:A system and method for regeneration of certain on disk dynamic control blocks for the file system after failure of access to the control blocks improves auxiliary disk storage system robustness. Regeneration of the dynamic control blocks is achieved without persistent replicas of the blocks on disk and thereby adheres to prior art disk formats. The regeneration control blocks are preferably used to support file system operation during backup of the disk, since loss of access to critical sectors for storing control blocks may portend disk storage system failure.
