Consider a RAID level 4 scheme with 4 data disks and 1 redundant disk. Assume that each block is 1 byte.

(a). For each of the following two cases of blocks of data disks, determine the corre- sponding the block of the redundant disk.

(i) 01010110, 11000000, 00111001, and 11111011.

(ii) 11110000, 11111100, 00111111, and 00000001.

(b). If the first block in each of the above cases is changed to 10111010, explain what changes must be made to the blocks in other disks to protect against data loss?
