Fusion Drive has corrupted my drives
About a three months ago I went to do a fresh install and Mountain Lion OSx automatically fusioned my SSD and HDD drives together. After looking online how to un-fusion the drives I got my system back to normal.
Today I when to do a fresh install because I was having problems with simple things like the terminal and updating to the latest version of OSx. When I restarted the mac to do an fresh install I get an issue stating that there is a drive error in both my SSD and HDD in disk utility on the boot up screen. it then says, do I want to fix it, I ok it but nothing happens. If I come out of the boot mode and restrat the OSx normally and the go into disk utility and check my drives everything is ok, so what gives.
This stupid fusion drive thing apple added to the osx has messed up my drives and all I want is my mac back to the normal state it was when I first brought it in april.
Any help getting my drives to work in boot up would be a godsend.
Thanks in advance,
Tyrone
"After looking online how to un-fusion the drives I got my system back to normal."
This would cause the issue you are describing. You corrupted your file system by destroying the logical volume.

If your volume was encrypted, the recovery partition won't be able to repair anything until it is decrypted. If you can't repair it:
According to Apple's FAQ, repairing a fusion drive erases it. Essentially, DU must reformat the drives. This makes sense:

My old hard-drive has corrupted and i have lost my library. i lost my back up too. I have restored all my purchased stuff but had 5000 songs uploaded from my CD collection. Is there anyway of transferring the CD tracks from my ipod or ipod to my iMac? Or do I have to manually upload the CDs again?

Hi,
I have a mac mini late 2012 i7 with 16 GB RAM, fusin drive 1.12TB. It became very lagging recently and after doing the first verify disk, I was prompted to reclone using time machine. Anyway I did a full restoration with my image and the problem still persist. And I did a verify disk again and this time it indicates the disk was ok and I even did a permission repair. Problem still persist and I did the PRAM reset and nothing helps.
I did a fresh mavericks installation. Initially it seems ok but after transfering more data into the system, the lagging seems to comes back. My suspicion was a hard disk failure on the 1tb hard drive.
Finally I did a diagnostic abd the test has this error code 4dd/11/4000000: sata (1,0) .
Does this means one of my drive is giving problem? As fusion drives comes with 2 drive I believe. One is 128GB SSD and the other is 1 TB drive.
My warranty has expired.
Thanks in advance for any help or adviseHi IIIaass,
Thanks for the reply. I have search on youtube regards to the apple fusion drive. However, I didn't find anything useful. I would like to know if it consists of 2 hard drives or just 1 drive. And if it consists of 2 hard drives, can I buy another ssd and merge the 2 together.
I do not have the tools right now to open up the mac mini. I have ordered it online and its on the way. If you have any information on this, please share with me.
Thanks -
I'm looking at buying a new computer. Has anyone had any problems with fusion drive on iMac? If so, what kind of problems, and were they easily corrected?
NOPE!
I better not! My iMac is only a week old. And, if I did have any problems with it, I would let Apple deal w/it! I do not troubleshoot when I'm under warranty. That's Apple job! -
How do I transfer my applications from a 2010 iMac to a new 2013 iMac that has a Fusion Drive?
What is the best way to transfer my Applications from a 2010 iMac to a 2013 iMac that has a Fusion Drive. I am particularly concerned about losing all my old mail. My documents have already been transferred.
The best way is to make a backup of your old iMac. Do this either by cloning to an external hard drive through SuperDuper or Carbon Copy Cloner. OR Use Time Machine.
Then set up your new iMac using either Setup Assistant or Migration Assistant.
See this link for more.

I want to buy for my new office, 2 pieces of iMac 21.5-inch Quad-Core Intel Core i7, 3.1GHz
8 GBSDRAM, 1 TB Fusion Drive.
I wan to be sure 100%, that this model has inside the new fourth generation Haswell processor.
I don't find anywhere "Haswell" write in the specification.
Please advice!If it is a Late 2013 model it has the Haswell CPU. Right you won't but Apple only sells the latest models on the main Mac store website and all others, last year models, get move to the Refurbished area or are sold off to Apple store or Apple authorized resellers.

How i know if my iMac 27'' has a fusion drive ?
hi
recently i bought a new iMac 27"
i wanna be sure if i have the fusion drive or not !!You can tell for sure if you click on the Apple menu at the top left of your screen and click on About This Mac. Then click on More Info, and click on the Storage tab. If you've got a Fusion drive you'll see something that looks like this:
You'll note the display above shows Hard Drive + Flash Storage, but it acts as a single hard drive.
I hope this answers your question. -
DIY Fusion Drive Problem (8,2)
Hey,
I wanted to go a step further and create my own DIY Fusion Drive. I had no problems installing the new ssd (128gb Samsung 840 Pro) instead of the hdd (standard mac hdd) and moving the hdd to the place where the optical drive has been.
I then proceeded to boot from a recovery USB Stick runing the mountain lion recovery partition on it. I configured both of these drives without any problems and finally created my Fusion Drive (visible in disk utility).
But here are things getting worse. My original plan was to recover from a TimeMachine Backup i created right before I started working on the Fusion Drive. But no, it said an error occured and I should restart the PC. After googling this error a little bit (and trying the recovery over and over again, different attempts to repair the time machine, which doesn't seemed to be broken etc.), I came up with the idea that my TimeMachine data could be corrupted and a whole backup is not possible. No problem I thought to myself.
You just try to install Mountain Lion fresh with your Recovery USB Stick and then get one or two folder from your backup that you need. But nope, installing Mountain Lion aborted with an error too while checking if my MacBook would fit the installation or something.
Last try: Cmd+R to start internet recovery. Downloaded the whole thing. Now I was able to reinstall LION fresh on my system (which of course would be the basic installation since my macbook came with Lion). Problem is: Lion doesn't know anything about Fusion Drive and I couldn't select any drive to install it on.
Right now I'm really thinking about installing the os on the ssd alone, what I didn't want to do. But I'm not seeing a possiblilty to get the system back up and running they way I wanted it to.
Now it's on you guys. My last hope. Do you have any ideas on how to fix this problem? I read so many guides and neither of them came up with the problems I have. They just say "and after configurating your fusion drive, you just install moutain lion again and you're good" :|
Thank you very much,
MrMützeI just tried what would happen if a delete the Fusion drive again. I was able to start the installation process of LION to my SSD, but Mountain Lion still aborted with an error while evaluating my system. So it shouldn't be a problem associated with the FusionDrive.

Disk Utility error when verifying DIY fusion drive
Hi,
It has been a while since I had to post a problem, but I need others advice on this if you can help. When 10.8.3 came out I installed an M4 512gb ssd in my main drive bay of 2008 unibody aluminium macbook and put a 1tb spinner in the optibay. Created a fusion drive, migrated data and all has been great. Decided to run disk utility today to check for any errors as I had a sleep issue with the 10.8.4 update which I ended up solving by changing the sleep settings in terminal - the issue had caused a few forced shutdowns. I have Disk Utitliy Version 13 (450). The Fusion drive is shown as the logical volume group followed by the volume disk. When I run a verify disk on the volume itself it is all ok:

I got the same when I did a safe boot and when rebooted from the recovery partition.y question is, do I repair or could it damage my setup? eg is Disk Utility being accurate and it can repair the error, or is it a phantom issue that should be ignored bearing in mind it's a DIY fusion drive and it could end up getting mashed?
Thanks!Hi,
The computer's running fine since I sorted the sleep issue. No issues as far as I can tell, which is why I was surprised to see the error. What does the error actually mean - is it saying that the volume is a different size than the computer thinks it should be and therefore it'll just change a few values? In which case I suppose a repair is harmless? I just don't want to repair and then reboot to find the volume corrupted. -
I'd like to create my own MAC Fusion Drive, but I'm not a dev so I need a little bit of guidance, which would also help a lot of people I'm guessing.
I am trying to follow jollyjinx's instructions, which are not that detailed. Specifically, I am trying to find the names of my two drives and I can only find one. Maybe the drives are not connected in a way to do this I'm not sure. I have a 750GB HDD and an 80GB SSD installed internally in my 2011 Mac Mini. I have been using both drives, SSD for the OS and a handful of common files and the HDD for iPhoto and iTunes libraries. A Fusion drive would be perfect!

I can only find one reference to a drive in the data, but maybe I'm missing something. Any help would be greatly appreciated!So far, so good! The article steps worked perfectly. I setup the Fusion Drive and then restored from my Time Machine Backup (from the SSD). I then moved the files over that were on the HDD (which I also backed up on my external drive. Everything seems to be working great! The volume was previously named 80 SSD OS X (to differentiate from the HDD) and it is still named that, although, as you can see from the screenshot, it now has a 576GB capacity (not 750GB, which is what I thought I put in there--my memory is horrendous! lol) ....not a big deal. I consider this a huge success at this point. Thanks again for the article!

Creating a Fusion Drive Safely
Hello. I currently have a macbook pro mid 2012 13 inch with a 256 SSD start up and a 1T regular hard drive with 16GB RAM.
Even though the 1T hard drive is in the DVD drive it sort of just acts like an external hard drive as it shows up as a separate drive in finder and I am wondering if one of you amazing people can tell me how to make a fusion drive in a way that is safe and time machinable, so that for all functional purposes I just turn on my computer and it looks like I have a 1.256T system that flows perfectly.
Also if this is achieved and I can time machine back it up; in a few years when I upgrade to say the new 2T Macbook pro ssd will there be any issues importing directly from time machine if my previous computer, the one I am using now, had or has a fusion drive.
Thank you.Oh, my solid stage 256 is where the original hard drive used to be and the 1terrabye regular hard drive is in where the dvd drive used to be. If the dvd drive is the optical drive then I should be having the correct hardware configuration.
If that is correct and I do have the correct configuration, can you please share with me a recommended link or procedure to follow for making me a DIY Fusion Drive.
I talked to one of the techie guys from Simply Computing yesterday (apple authorized dealers in canada) and he said that he has this setup and it works great and when I mentioned about performance, he said that there is a slight reduction in speed and described it as, "A normal solid state is 4 times as quick and with a fusion it is 3.5 times".
If all this info is correct I would just like to proceed with it and get a recommendation for how to do it or a suggested link that has been used and proven to work for such DIY Fusion Drives. Is the one that I shared good enough for it. Thanks everyone for your kind time and attention to this. -
Creating a Fusion Drive ?
Hi All,
I have a mid-2011 iMac which I plan to install a Samsung 840 Pro SSD to use as part of a Fusion Drive setup.
Typically I backup using Carbon Copy and wil be taking a backup prior to the mod.
Once the drive has been configured...... will I need to reinstall the OSX from scratch, or is it just a matter of bringing back the Backup ??
PeteWhen you use CoreStorage to format the SSD and mechanical HD it will be a destructive format/paritioning so the new Fusion disk will look like one HD but in fact will be two under the hood. You should be able to use CC to restore your image as it will look like a single drive.
I'm not sure if that model iMac has a Fusion tool supplied by Apple or not. I think you have to use one of the many guides found online to manually configure the drives to be a single Fusion drive using diskutil at the command line. If I remember correctly, you'll need to boot with a thumb drive with 10.8.3 installation on it. Then go to the Terminal to configure the Fusion drive setup. Then you would have to find some way to run CC from a bootable thumbdrive, etc. I think you could boot the backup disk made with CC then run CC from it to clone to the new Fusion drive. That should work. Worse case scenario, you always could just re-install OS X on the Fusion drive and then use the Apple Migration Assistant to grab your data from the CC'd drive.
Either way, give yourself at least half a day in the event you run into issues and have to work around things. -
First off I have a 3tb fusion drive.
I created a 200gb bootcamp, I tried deleting the bootcamp because I thought I messed it up and googled how to delete a mac partition which told me to use Disk Utility, did that and then erased it and somehow it got locked and wouldn't let me do anything to any partition on my hard drive (everything was greyed out)
After looking up and googling for hours I found a post saying the only way to fix it would be to go into CMD+R and go into the terminal window and type out disklist and then find the first UUID number and do something along the lines of disklist delete (UUID) i forget the exact formula. I did this, and then I had 3 separate untitled hard drives.
One in the size of 1.9gb on in 800gb and one in 121.3gb (which is the SSD), I put my time machine backup onto the 1.9gb untitled and now my computer is booting slowly (because it's no longer running off of the SSD and the original bootcamp is still there.
To be honest I am absolutely confused on what else to do!
Is there anyway I can fix this?How do I go about deleting and then re-adding the hard drives? Completely lost on how to make it back to being a 3gb fusion drive.
Thank you for all your help, I honestly really appreciate it.
I followed your instructions and got the following

Programs repeatedly crashing on my late 2012 Mac Mini Fusion Drive
I have a late 2012 Mac Mini Fusion Drive 2.6ghz, 16gig RAM running Mac OSX 10.9.4 . For the past week or so I have had a number of programs - both Apple and third party apps crash repeatedly, I have repaired permissions and restarted numerous times but nothing seems to fix it. For example Mail would crash each time I cancelled a password being accepted by Mail in a particular account, Safari has crashed for various reasons. Apple Motion has also crashed more times in the past day or so than it ever has in the past year. It's crashing when I try to add a point or node to a line in an animation I'm finishing.
Does anybody have any idea why this is happening now and does anybody know how to fix it?Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
For this step, the title of the Console window should be All Messages. If it isn't, select
SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter the name of the crashed application or process. For example, if iTunes crashed, you would enter "iTunes" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Select the messages from the time of the last crash, if any. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
☞ The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
☞ Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
In the Console window, select
DIAGNOSTIC AND USAGE INFORMATION ▹ User Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of crash reports. The name of each report starts with the name of the process, and ends with ".crash". Select the most recent report related to the process in question. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
If you don't see any reports listed, but you know there was a crash, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report—they're very long and rarely helpful. -
DIY Fusion Drive on MacBookPro8,2
Yes, I know it's not supported out ot the box.
I've been trying to set up a DIY Fusion Drive on my Early 2011 MBP 15" with no luck.
I've been googling a bit and found several others reporting the same problems on the MBP8,2. Seems this setup works on most Mac's, just not this model. Has anyone gotten this to work with any sort of hack? Please share your experience.In case you are not already aware of these resources here are some links
http://blog.macsales.com/15617-creating-your-own-fusion-drive
http://www.macworld.com/article/2014011/how-to-make-your-own-fusion-drive.html
There are others, but the most salient point from the first link is that it alleges the 2012 Mini is the only Mac that uses a version of Disk Utility capable of creating a Fusion volume. This sounds dubious to me though since I find it hard to believe CoreStorage is dependent upon a version of Disk Utility that exists only for the Mini. The only reason I mention this is that I consider OWC knowledgeable about the subject.
Without further details of how you intend to accomplish this I am curious how you justify the following comment:
The OS handles where the files go so I can use the time to work instead of managing where the files go for best performance.
We know Apple's Fusion Drive accomplishes these actions in firmware or software that exists in their new iMacs, but what resource led you to conclude this ability exists in your MacBook Pro, or anything other than the current production 2012 iMacs for that matter?
If you are certain it does, I may do it also. I like challenges too.
