Several methods and apparatus to single XOR operation weaver reconstruction of a failed drive of a raid are disclosed. A failed drive of the drive group implemented in a WEAVER code with an (n,t,t) layout is determined. A set of scatter/gather lists is produced from a number of the other drives of the drive group. A scatter/gather list is created by modifying a pointer data of the set of scatter/gather lists. An additional scatter/gather list is generated from the set of scatter/gather lists. A single XOR operation is performed on the data segment, the parity segment, the additional data segment and the additional parity segment to form a resulting scatter/gather list including a resulting data segment and a resulting parity segment. The resulting data segment and the resulting parity segment are written as sequenced in the resulting scatter/gather list to a replacement drive.
