Mac Os X doesn’t recognizes a 3TB partition on an external WD 3TB green drive that was used before as internal drive.
hdd: WD30 EZRX-00DC0B0 - SATA/64MC cache
os: Mac Os X 10.8.? (as internal) , Mac Os X 10.9.4 (as internal) , Mac Os X 10.6.8 (as external) & Mac Os X 10.10 (as external)
I’m using a WD Green 3TB as backup disk in my computer as internal for more than on year. The drive was working fine by then with Mac Os X 10.8 & Mac Os X 10.9.
I decided to work while traveling and put that hard drive in a external USB 3 enclosure to be able to use it while on my journey.
I’ve tested it on 2 laptops (with Os X 10.6 & Os X 10.10) and I always get the same result:
- The physical drive of 3TB is detected (In disk utility I see as mention with it WDC WD30 EZRX-00DC0B0) but it’s partition shows as a grayed out (as unmounted) MS-DOS (FAT) partition named DISK2S1 of 3TB. I can’t mount the partition so can’t access my data.
- I could format the whole thing but this is not an option as critical work data is on it.
Is it possible that I need a (e)SATA conection to be able so that the computer can recognize the partition?
At the moment I’m on a place where they have only older computers without SATA support.
Please help me as I’m getting a little desperate.
