i get the disk read error when i start up my 40gb hard drive. and since i have a 80gb one, i put it as a slave and try to transfer the files, then reformat the 40gb one. but i cannot get it to read the 40gb. at first it didnt work, i tried setting them to cable select, slave, master, no pins, and nothing. then i switched the IDE cables, and then the bios finally read both of the hard drives. but when i open up windows with the 80gb one, it wont read the 40gb in the my computers window. can any help? i ran out of ideas.
