What are you using to format it? Disk Utility shouldn't have an issue with that model SSD.

Neither. It must formatted in GUID to work with Mac OS X.

I use MS-DOS on a Macbook to format all external mini disks and they work just fine and also work transferring data to Windows.

One other possibility - some new disks come in NTFS: This is a more recent Windows' default file system than DOS. Windows can read and write to NTFS-formatted drives. OS X and Linux can only read NTFS-formatted drives, not write to them (format)—unless you have a third-party driver like NTFS-3G installed.

To claifiy my answer if you are going to use a Disk as a BOOT SOURCE FOR MAC it must be formatted in GUID.

It could be the optibay - not the SSD. OR the cable for the Optibay. What exactly did you purchase from iFixit... and have you contacted iFixit customer service about it using the link at the bottom of this page? WE ARE NOT IFIXIT CUSTOMER SERVICE This is the volunteer self-help forum. We are not iFixit employees... just DIYer (maybe with more experience) like you.
