Hello everybody! I need your help and support It's a long story. What I have: 1. Internal HDD with Mac OS that works normally 2. External HDD with Time Machine copies 3. SSD Sumsung 840 Pro 256GB 4. Broken Sata3 cable that goes to HD bay 5. Optibay that works normally 6. External enclosure for 2,5" SATA3 to USB that works normally What I need: Install Mac OS on SSD My actions: 1. I put SSD in optical drive bay through optibay and tried to make a recovery by Time Machine copies - recovery always been stopped (max progress is 19%). SSD's been formated "Mac O S Extended (Journaled)" with a single GUID partition 2. SSD stayed in optical drive bay and HHD with Mac OS been connected via External enclosure. I tried to copy mac os ob SSD using Carbon Copy Cloner - copying always stopped (i tried several times - max progress is 11 GB been copied). SSD's been formated "Mac O S Extended (Journaled)" with a single GUID partition 3. I tried to re-install clean mac os from Recovery HD from boot menu - downloading passed with 2 errors and installing failed too (I tried two times - max progress is 10 minute remaining) 4. Between step 2 and step 3 I tried Time machine option again but I didn't formated SSD. Installing of the copies passed with a lot of errors "no such file or directory". somehow system been copied to SSD.... BUT it's always hanged. For example I tried to measure speed of the SSD - and system hanged. It always hanged after 1-2 minutes after starting. Is this SSD problem or I was doing something wrong??? Please support!! Thanks.
