Last night I had completed my dual 250GB samsung EVO 840's on a Sonnet Tempo card in RAID 0 striped config, a 2TB RAID 0 set up on some WD black HDD and was feeling pretty happy, got my Samsung U28U590D 4K screen working and all was well.
Tried to install a fresh version of Autodesk Smoke and it wouldn't let me, kept saying there was the application already installed... searched and found a number of hits in the:
~usr/bin directory...
well, it just so happens that if you delete the ~usr folder, the whole world falls apart
(being over dramatic) well, that was interesting... I had completely buggered my system,wouldn't shut down, wouldn't boot, wouldn't boot off of the recovery disc, wouldn't go into recovery nothing just a mac symbol and loading bar...
DAMMIT
I remembered I had an old SATA 2 SSD knocking about with mavericks on which was cloned with CCC before I upgraded to Yosemite, so I whipped out all of the drives and put the old SSD in, after a while success it booted into mavericks and from there I was able to reinstall a fresh copy of OS X 10.10 onto the RAID 0 PCIe SSD's and I was back to where I was 24 hours ago...
Long story short, it always pays to have a copy of a bootable OS handy if you are a novice...
