Now 1 month since Apple introduced us to his new tool called « Fusion Drive »
But what is it?
It's simply a tool to combine an SSD with a HDD and make a single disc says "logical". On this volume, the OS and applications are on the SSD while the files on the HDD.
Yes, but what's the advantage over a system with two separate disks?
And well, Fusion Drive takes care of automatically put files that are used frequently on the SSD to gain speed, while the rest is stored on the HDD. In addition, there is nothing to do. Everything is automatic.
On the other hand, who says combine two disks say combined the risk of failure. So for all those who will try the Fusion Drive experience, think you make a Time Machine backup (or other).
Apple released the Fusion Drive option for €250 (without saving of space compared to the standard version). So the question that some developers are asked is:"Is Fusion Drive configurable on an old mac?"[/ url]
Well Yes, and even better, Yes on unsigned Apple hardware. Let me explain; It is possible to create a logical disk with an ocz SSD, a WD HDD in USB and a seagate SATA HDD. Short with everyone including our hackintosh
But how are we doing?
And well, you need at least two physical disks (the best being an SSD and HDD, but no obligation), a USB key to install osX 10.8.2 and a little patience; this manipulation is possible from osX or the osX Installer.
[note=attention]What you need to know:
- Create a logical drive deletes all data
- I am not responsible for troubleshooting;)
Part I : Creation of the FusionHD
First, we launch the terminal and we list the disks with the following command:
The result looks like this:
I'll use my drive n ° 5 and n ° 6 (Yes it is a HDD in USB and a USB;))
Next, we'll create the logical volume with this command:
sudo –s diskutil cs create "Fusion Drive" disk5 disk6
The result looks like this:
Well hold the line with written LVG UUIDS and copy it
« 9C0EB8E8-8525-46EF-85EF-FC7BB6A44823 » for me.
You will say, "I see nothing?" it's normal, it just created the disk, not the Volume
So, let's create it with this command:
diskutil cs createVolume 9C0EB8E8-8525-46EF-85EF-FC7BB6A44823 jhfs+ "FusionHD" 100 %
And here is the result:
You now have a physical FusionHD with your two disks disk.
Part II: Make FusionHD Bootable
Now that you have installed osX 10.8.2 on your new disk Fusion Drive, the problem is going to be to start it without "help".
For this you need the folder of chameleon.
Don't add this, it could break Facetime and iCloud
Now, let's copy our extra file on s3 partition of our two disk.
To do this, we do like this:
sudo –s diskutil list
I get this:
Now, we are going to mount those partitions to copy the extra folder in:
diskutil mount disk5s3 cp -R /Volumes/Machintosh\ HD/Extra /Volumes/Boot\ OS\ X/ diskutil unmounts disk5s3 diskutil mount disk6s3 cp -R /Volumes/Machintosh\ HD/Extra /Volumes/Boot\ OS\ X/ diskutil unmounts disk6s3
Do it again for files boot0 and boot1h, simply swipe your Extra folder in the terminal window to directly gain the right path.
diskutil mount disk5s3 cp -R /Volumes/Machintosh\ HD/boot0 /Volumes/Boot\ OS\ X/ diskutil unmounts disk5s3 diskutil mount disk6s3 cp -R /Volumes/Machintosh\ HD/boot0 /Volumes/Boot\ OS\ X/ diskutil unmounts disk6s3
diskutil mount disk5s3 cp -R /Volumes/Machintosh\ HD/boot1h /Volumes/Boot\ OS\ X/ diskutil unmounts disk5s3 diskutil mount disk6s3 cp -R /Volumes/Machintosh\ HD/boot1h /Volumes/Boot\ OS\ X/ diskutil unmounts disk6s3
And finally, you need to restart your computer into thinking to put one of the two disks as a priority in order to start on it.
Part III: Test of the FusionHD
next coming soon
