  Hello

  On a new iMac (end of 2015), I need to wipe my drive of Fusion of 3 TB (El Capitan, unencrypted, just 1 partition, no Boot Camp partition) and then restore a backup Time Machine (made on a previous iMac, also with disc Fusion of 3 TB (El Capitan, unencrypted, just 1 partition, no Boot Camp partition).

  4 choose the most recent backup

  5 selected "Macintosh HD" as a destination and click "continue".

  ... but then the following message appeared "disc cannot be erased.

  2 choose disk utility

  3 choose "Macintosh HD"

  How to restore my backup Time Machine - nothing more or less - to my new iMac?

  I lost 3 days now with this problem. I really hope someone has a solution.

  Thank you very much!

  Apple did not provide an easy way to recover from this condition. If you are not able to carry out these instructions, please someone more experienced to help you get. One option is to take an appointment 'Genius' on an Apple Store.

  Starts the Internet recovery mode by pressing the key combination command-option-R to start ringing. Release the keys when you see a spinning globe.

  Note: You need an Ethernet or Wi - Fi connection permanent Internet to use recovery. It will not work with modems USB or PPPoE, proxy servers or networks that require a certificate for authentication.

  In the OS X Utilities screen, select

  Utilities ▹ Terminal

  in the menu bar at the top of the screen, not one of the items in the OS X Utilities window.

  Follow the steps in this thread to ASC to split the fuser unit. The long string of letters, numbers and dashes you will need to enter will be different in your case. Copy and paste into the command in the Terminal window.

  This will remove all data from the fuser unit, then you had better be sure of your backups.

  Quit the Terminal, and then repair the Fusion drive (see "Troubleshooting" on the linked page.)

  Quit disk utility. Then you should be able to install OS X and restore your data from a backup in the main screen.

• Fusion drive does not start?

  • MacBook Pro mid-2009
  • Running OS X Yosemite
  • 320 GB internal HARD drive
  • replaced the optical drive with 240 GB SSD
  • replace the 4 GB of RAM with 8 GB of RAM

  After the replacement of my optical drive with an SSD, I booted the laptop and checked the disk - it showed up as a normal external drive. I then, in accordance with the guide to formatting a drive of Fusion (combined capacity of the two HDD and SSD), found here, booted the laptop into recovery mode at the entrance to the commands in the terminal. the commands I entered were the following sequence

  diskutil list

  diskutil cs create disk1s2 disk0 [ArbitraryName]

  diskutil createVolume [UUID here] jhfs cs + [ArbitraryDriveName] 100%

  After that, my records indicated were over 240 GB SSD and Macintosh HD 320 GB but Fusion drive 560 GB - I thought: Hey! great, it worked... However, when I restored it to my time machine to the top of my 3 TB external hard drive, which took a few hours, I was met with the error gray screen instead of a login screen.

  I have my time machine to the top, so im not worried about my data, but when I was able to boot into recovery mode (when it is connected to 3 TB external HD) I deleted the Fusion drive and tried to reinstall a new OS from Yosemite, but of course this returns the same error as before starting. This leads me to believe something is damaged with the fusion drive, maybe its lack of OS startup, but would not restore or reinstall OS to solve this problem? I ran a diagnostic on the drive of fusion are deleted and it gave me the error code of output 8. I will update with a screenshot of the Terminal

  What can I do to cancel my fusion drive and try to start over again?

  any help would be greatly appreciated...

  I don't know about you, but I thought that the HARD disk must be placed in the Bay of optics and the SSD drive in the HARD drive Bay where the original HARD drive is.

  So, have you tried to reverse the readers in the bays (SSD in a drive Bay HARD and HARD drive in the Bay optical) and recreate your Fusion drive and then either restore or install OS X?

• a fusion drive is good for audio recording?

  I think buy a 27-inch iMac for audio recording on Logic Pro X, but is not sure a merger player performance, because some say that the part of the HARD of it on only 5400 RPM drive, if I hold with an iMac HARD 7200 RPM drive?

  You will likely get different opinions, but personally I would not use the fusion drive and recommend an SSD.

  Quite significant speed difference.

• fusion drive

  I just start up my iMac 27 "that I received in August 2016. I ordered a Fusion 1 TB drive. What is the profile of what it says. How will I know that's what I ordered? Somehow this iMac has no help.

  

  Go to Apple > about my Mac > system report > navigate the material, then click SATA. A regular reader will have an entry as well as the size shown below; a fusion player lists an SSD and a normal HARD drive. Mine has a HHD & SSD, but they have not been defined as a fusion drive:

  

  Then you should see a 1 TB HHD and then a 24 GB SSD hard drive (maybe 128)

• Help required with the MacMini Fusion Drive

  Hi all

  I recently bought a second hand end 2012 MacMini i7 wth a fusion drive. The previous owner had created a windows partition. I don't want to return the machine to its original out of the box factory for my use, as I did not need to run windows on it.

  I'm fighting to get the fusion drive to merge. Currently, I have two separate discs that I named her 329 and 781 GB. Disk utility shows that both drives are very good. I rebooted into Recovery Mode to use online disk utility and readers are not displayed in red, and so there is no option to fix them.

  I used the Terminal (after reading online) and it provides the following information:

• Dedicated graphics (A1398) driver problem

  My Macbook Pro (A1398) dedicated card (Geforce GT650M) graphics driver problem.

  Installation of the drivers of web from Nvidia (WebDriver - 346.03.10f02.dmg, WebDriver - 346.03.10f01.dmg, WebDriver - 346.03.10 b 01 .dmg) with CUDA drivers (cudadriver - 7.5.29 - macos.dmg) and toolboxes CUDA (cuda_8.0.29_mac.dmg and cuda_7.5.27_mac.dmg) does NOT.

  When I tried to install Caffè/CUDA (used for Machine learning), my card (Geforce GT650M) dedicated graphics card driver has become corrupt (seen through the Console).

  Dedicated card random is more gets reported under 'report system' (probably due to the problem of driver).

  Attempts to restore have been hit and Miss so far.

  I downloaded the drivers from Nvidia web (WebDriver - 346.03.10f02.dmg, WebDriver - 346.03.10f01.dmg, WebDriver - 346.03.10 b 01 .dmg) but they have only worked / failed randomly when combined with CUDA drivers (cudadriver - 7.5.29 - macos.dmg) and toolboxes CUDA (cuda_8.0.29_mac.dmg and cuda_7.5.27_mac.dmg).

  Only the internal graphics card Intel Graphics 4000 is constantly working.

  I cleaned the system (by removing all traces of the nvidia drivers and drivers of coda) while that to reinstall these drivers in different combinations.

  Yet, the conclusion is that it is all the success and the miss.

  Sometimes it worked I could test samples CUDA.

  Other times, that it worked, but the laptop would freeze randomly.

  Then, he failed once again and returned to map internal Intel completely.

  It was suggested that I should be able to restore it by reinstalling ElCapitan

  I don't have the luxury of reinstall ElCapitan.

• Fusion drive how...?

  Hello

  The other day I saw a post with a link to a Web page on how to create your own Fusion player. In my view, that it may have been an Apple Web page.

  However, I forgot to bookmark.

  Basically, I have a Macbook Pro mid-2012 13 inch Non-retine compatible with having a third of road merger.

  I would like to know what hardware is recommended for the creation of a third party by car merger?

  (1) what hard drive model?

  (2) what SSD model?

  Also can you use boot camp with a third party by car merger?

  You can create more partitions on a drive of Fusion and install OS X, MS-Windows, Linux, etc...

  -Thank you

  The indications that I used to create a Fusion drive in my Mac Pro are located at http://blog.macsales.com/15617-creating-your-own-fusion-drive

  For my SSD, I used the card of mercury Accelsior E2 PCIe SSD and HARD drive, I used a 1 TB drive installed in my Mac Pro. He played very well.

• Restore factory for 3 TB Fusion Drive settings

  I should just come here first, Apple phone support has been no help at all, took two officers to just make me an appointment at the Apple Store for tomorrow.  I'm sure they were also just guess what to do.

  I decided to format and restore my iMac with screen Retina 5 k, there is a merger of 3 TB drive.  I would just restore the drive to merge its factory settings which seems just a partition that includes the SSD & HDD together... I think that RAIDed... I'm not really sure, I've been googling and I am even more confused now.  I'm having the hardest time and whenever I try to delete a partition or delete something that I feel like I'm making it worse, which is why I called Apple, but they were not useful.

  Does anyone have any suggestions?  I have no other drive connected to my iMac.

  Is there maybe a terminal command to restore the unity of fusion to its original state so I can install El Capitan again?

  I've attached a picture of disk utility where I left with telephone support from Apple.

  

  N ° the SSD & HDD are not searched in a merger player. They linked together in a logical volume so that the data can be promoted and demoted to maintain the data that you use on the SSD and the data that you do not use the HARD disk. Giving you the SSD performance but a hard disk storage space.

  You will find indications to recreate your Fusion drive to the http://blog.macsales.com/15617-creating-your-own-fusion-drive

  I hope that you have a backup because only when you have completed this procedure the Fusion drive will be empty.

• -Portege Z10t 13 V graphic driver problems and lag with W10

  Hello

  Please excuse my bad English,

  I just bought the Z10t A 13V PT 141, with W8.1. This computer works fine on W8, but I want to install W10. I already tried 3 times but each time, the cursor (with the touch pad or mouse) is lagging behind, each movement is jerky and works very well. I tried to see if it was a driver problem and downloaded new drivers from Toshiba for the W10.

  I did the same thing with Intel drivers, but for graphics drivers, there is an error message: "a custom computer manufacturer driver is installed on your computer. The Intel driver update utiliy is not able to update the driver. Install a generic Intel driver instead of the driver from the computer manufacturer custom can cause technical problems. Contact your computer manufacturer for the latest driver for your computer.

  When I'm with W8, drivers are correctly updated...

  So I think that the cursor problem is due to this driver problem (I hope so, but I'm not sure). What is the solution? I'M alone with this problem?

  Thank you

  Thomas

  Hello Thomas,.

  EXACTLY the same problem here with my uograded Portege Z10t-A-140 to WIN 10.
  I also took the same steps and encountered the same problems and no solution.
  I find Toshiba after sale customer VERY INEFFECTIVE and disappointing, because it seems no way to get a support PROFESSIONAL from Toshiba on this issue (or any other for that matter).
  Note that I absolutely do not consider helping other users on a forum or self-help a form of professional support at all!
  -> Not happy with Toshiba!

• Sound driver problems

  Hello world

  I reinstalled windows in my computer after you have removed all the files it contains.

  Therefore, I unfortunately lost the recovery partition.

  Now, after you have reinstalled the Windows 8 Pro, I installed all the drivers and everything works normally except the sound.

  However, I have been using Ubuntu after reinstaled Windows and I DIND'T have no problem with that.

  I thought that maybe this could be a problem inside, but when I use me headphones, or when I use my computer with my TV with HDMI, the problem persists.

  My computer is a HP ENVY m6-k010dx Sleekbook.

  So, what shoul I do to have it fixed?

  (Sorry for my bad English )

  ---------------- UPDATE ----------------

  I use a Linux Live USB to test the sound, as it could be any physical problem.

  However, it turned out that it really is a driver problem.

  I found a solution

  Just after installing Windows 8.1 the problem fixed itself

  Thanks for your help ():

• My cd rom seems to have a driver problem

  Hello

  My cd rom seems to have been corrupted and I have a message from code 39. How can I use my recovery disks when the cd rom is not working. I have an old computer that has XP loaded, I can load my inside recovery disks & copy on an external hard drive and then copy it on my laptop which is a HP Pavilion dv - 7 3111ea.

  Thank you

  Hello

  Unfortunately, it is not possible to do what you suggest.

  However, the CD/DVD drive should still work with your recovery disks (unless there is a hardware problem with the drive), because when you start the laptop computer, the drive is controlled by the Bios, no windows - code 39 refers to a driver problem Windows.

  You may be able to correct the error of the Windows driver as follows.

  First, try the automated Microsoft fixit at the link below.

  Windows 7

  Vista

  Check if the drive works now.

  If the drive does not, in the Menu start, open all programs, open accessories, right-click on command prompt and select "run as Administrator".  In at the prompt, type the following command and press ENTER.

  sfc/scannow                (Note that there is a space between sfc and /)

  Let the entire process, then the output type and press ENTER.  Reboot the laptop.

  When windows is completely reloaded, click on the Start Menu, open Control Panel and click Device Manager.  Click to open the CD/DVD-ROM drives.  Right-click on the drive and choose uninstall.  Do not delete if requested drivers.  When the device has been uninstalled click the icon 'Search for hardware changes' (usually just below help in the toolbar).  Let windows reinstall the disc and see if it works now.

  

  Kind regards

• Driver problem with a dc7100 cmt

  I have a driver with my Hp dc7100 cmt tour 7 months ago, I upgraded Windows Xp pro to Windows 7 Edition System Home Premium, it was working fine... or so I thought, then week or so I did a Windows update that has problems starting

  Windows 7 upgrade advisor has been downloaded in my system, I started to have a driver problem he always tells me to update my drivers for systems, I well updated some drivers but I was not of the most important of them.  It is a Graphics driver (WDDW) driver for windows aero graphics would work my CD-Room go stale and USP port pilot who was also outdated... The player windows Media have also stopped...  He told me to contact my PC manufacturer or retailer to see it an upgrade is available, I've been looking and asking for two days... I hope someone reading this and can give me some advice on how I can get these updates, or tell me why I can't get HP... My goal is not to get out a purchase of a new system, but fix the one I have... as a student, my funds are very low!  Pease Help, thank you

  Hello:

  What graphics card you have in your PC?

  You mentioned Aero, and you wouldn't get Aero on a dc7100 with the integrated Intel graphics card.

  You'd only Aero, if you have a PCIe x 16 graphics card is windows 7 capable.

  If you have the Intel integrated video card, I got something that will install the video driver, but you won't have Aero.

  In addition, he will work for W7 32 bit.

  So, please post back and let me know what video card you have in the PC, because if it's an add-on, one, I would need to know the manufacturer and model.
