Issue after replacing optic bay
I have mid 2012 Macbook Pro 13''. I've replaced optic bay and insert second hard drive (SSD) on it's place. But when I wanted to erase SSD via Disk Utility - there begin the problems. I couldn't do that. Then I put SSD to the main bay and replace HDD to the optic bay. Everything was fine. I install Mavericks 10.9.5 on SSD but when I load it my HDD works very slowly.
At my ex-MacBook Pro 2009 there wasn't such issue.
I read that EFI 2.9 update will fix it but I couldn't install it - the warning that this fix is incompatible with my OS appears.
Please help me)
