A power failure that occurs while a disk block is being written could result inthe block being only partially written. Assume that partially written blocks canbe detected. An atomic block write is one where either the disk block is fullywritten or nothing is written (i.e., there are no partial writes). Suggest schemesfor getting the effect of atomic block writes with the following RAID schemes.Your schemes should involve work on recovery from failure. RAID level 1 (mirroring)
