My friend's computer just mess up his harddrive arrays. he got "NTLR" problem at beginning. he should just make a change in BIOS that set boot sequence to array drive first, then he should be able to enter windows. but he can't find the array drive. it messed up. Now my question is: how can he set up the new array without delete the all data in his disk?(he got 2 IDE Harddrive and 1 serial harddrive).
