Mid 2012 MBP 13"+Samsung 830 in optibay=Fail; Success in HDD loc
Here's what I've got:
Mid 2012 Macbook Pro, 13", base model (MacBookPro9,2 ; 2.5GHz, 4GB DDR3)
OS X V10.8.2
EFI Firmware (2.9, downloaded and installed 10/4/2012)
Samsung 830 SSD, 256GB, with Jan 2012 firmware
BrainyTrade Hard Drive Caddy from Amazon
Used Migration Assistant to copy data from old MB (2006), running Snow Leopard.
SuperDuper
I finally got the Samsung 830 working (boots, runs great)
in the primary HDD location, and the HDD works fine (boots, runs well) in the optibay using the
Amazon/BrainyTrade Caddy but the SSD would not work the other way around.
To recap the failure:
1) Upgraded OS and EFI firmware
2a) Tried initializing SSD in external USB/FW enclosure, single partition, GUID, copied HDD to SSD using SuperDuper, made bootable, checked out ok. Put in Caddy, swapped out optical drive, put SSD in caddy inside, rebooted, got "Disk is not recognizable, Initialize...".
2b) Tried initializing SSD internally after confirming external operation of SSD and wiping, got same error. During attempt to initialize, got "Waiting for the disks to reappear" for > 20 minutes in Disk Utility.
3) Confirmed proper operation of Optical drive and cable
To recap the success:
1) After having previously upgraded the OS and EFI firmware...
2) Put SSD in primary HDD location
3) Put stock HDD in optibay using same caddy
4) Booted fine to HDD in optibay by default actions (took a little longer)
5) Initialized SSD in the primary HDD location (single partition, GUID)
6) Copied HDD to SSD using SuperDuper, made bootable, (took about 1/3 the time as via USB)
7) Set MBP to boot from SSD, checked out ok. Initial impressions are "nice and quick".
So, the Mac works, the caddy works, the HDD works, and the SSD works. Only thing that wouldn't is the SSD while in the optibay - for me, it won't initialize or be recognized as initialized.
It appears that the architecture is sufficiently different between the primary drive location and optibay, and that Apple's EFI firmware (v2.9) is not currently sufficient at this date (early Oct 2012) to support a Samsung SSD in the optibay of a 13" MBP.
Has anyone gotten any SSD (perhaps an M4) to work in the optical slot on a Mid 2012 13" MBP? It appears that OWCs caddy and Mercury SSD drive are working according to their website.

Any others?
And lastly, I originally selected the other configuration to get the HDD damping and motion/drop sensor active on the HDD, so wanted the HDD in the stock position). If I keep the HDD in the optibay as it is now, is that an issue I should be concerned about?
