I replaced my CD drive with a Western Digital 750GB hard drive using the iFixit guide.

My Mac for some reason throws error on any interaction with the hard drive, for example on disk utility when I tried to create 1 partition of FAT:

disk utility failure on 1 partition

When I try to setup BootCamp I get this error:

bootcamp error

I have successfully managed to erase and format the hard drive while booting up to GParted, but I want to install windows on it.

Do you have any suggestions? Ideas?


I recently ran into this issue as well. I originally suspected a damaged SATA cable, but swapping the SSD into the optical drive bay and the HD into the primary hard drive bay solved the issue for me.
