Yesterday I installed a MCE OptiBay into my mid 2012 Macbook Pro 15". I ordered the kit from MCE that included a 1 TB 7200 rpm HDD. Install went fine, but I had a few issues trying to format it. First I wanted to make a 100 GB partition for Windows 7. Boot camp assistant would not do this. It spit out an error which I can't recall. So I decided to re-format the drive in journaled (as it already came in journaled). Boot camp assistant still did not work, but then it randomly decided to allow me to make the partition. Rebooted and went through the install via a bootable USB stick made with boot camp assistant. When it got to the part to choose the partition I couldn't select the one labeled "BOOTCAMP" so I tried to format it in the setup. This did not work. Tried deleting the partition, remaking it in the Win7 installer and still nothing worked. At this point I thought I would just keep the bootcamp parition on my main SSD boot drive. So I went to start fresh and format the OptiBay drive again which sometimes works and other times it doesn't. I noticed if I run 'verify disk' or 'repair disk' it spits out a bunch of errors posted below. I've read some posts that say you can't install a boot camp partition on the OptiBay without swapping around the drive to the primary and jumping through some hoops. On the other hand I'm wondering if I have a bad drive or what's going on with this?
