I followed this guide to place a samsung 840 EVO 750 GB ssd in the optical drive bay. The instructions worked near perfectly. However, I got many SATA CRC errrors. Not a connector seating problem. After placing the SSD in the hard drive bay (following the hard drive replacement guide) no more CRC errors.

I tested with an older laptop hdd: This works fine in the optical bay.

Apparently either the optical drive bay does not work well with the samsung 840 EVO or my optical drive cable is no good.

I reassembled my superdrive and placed the SSD in place of my built-in HDD for a nice speed increase.

Is there any listing of ssds that work well in the OD bay?
