The drive crashed on my 13" mbp, I got my replacement drive in the mail since it was under warranty still but when I go into the utility to partition the drive for install it's no where to be found. It spins up fine but it won't show up. Is it likely the drive is bad? Will a damaged drive still show up in the disk utility? Any ideas? Ps I replaced the hd cable a few months back and it worked at the time but I haven't used this laptop since then.
