Found out that booting Yosemite 10.10.3 external USB 3.0 enclosures renders all internal SATA drives inaccessible.
Here's what I did:
1) Installed Yosemite 10.10.3 onto Samsung Evo 850 500GB SSD in Vantec Nexstar 6G USB 3.0 enclosure. This is a fresh, bare install of 10.10.3 - nothing else.
2) Booted from the same Vantec USB 3.0 enclosure on a 2012 Mac Mini 2.5 i5, 4GB, 500GB HDD.
3) After boot, the internal drive is completely inaccessible. Not visible in Disk Utility or Finder. Not visible after NVRAM/PRAM reset (Option+Command+P+R boot).
Just in case my Mac Mini was wonky, I tried the steps (2) and (3) on a 2011 iMac 21.5 2.5 i5 quad, 20GB, 2TB HDD - SAME RESULTS.
After after wasting another hour poking around between the two Macs, I gave up and re-installed 10.10.2 on the same Vantec USB 3.0 enclosure and booted off the Mac Mini and the iMac - VOILA!!! - the internal SATA drives magically reappeared.
Anyone else experiencing this?
Any solutions?
