Yosemite 10.10 problem - 10.9 drive not mac extended format ??

I am attempting to upgrade to 10.10 and the system is not allowing me to install on my 10.9 drive because it thinks the drive is either not mac extended formatted or journal not activated.  It will not install the update.  It requires a drive format or activate Journal.  I'm new to Apple and this does not compute!  The system says the 10.9 drive is formatted as mac os-extended (Journal).
Thanks,

The other thing that the installer checks on before it install OS X is that the disk drive is formatted with GUID partition mapping.

  • How to format Windows drive with Mac OS format

    Hello
    I have a Windows 160gb internal drive that is formated in Fat32. I am unable to format this drive with Mac OS X 10.3.9 in order to install Tiger 10.4. When I attempt to format using the Mac OS extended (journaled), I receive an error (sorry I didn't write it down) partition error. If I use the Mac OS extended option I recieve an error that the drive can not be unmounted.
    How can I format this 160gb drive with Mac OS format so that I may install Mac OS X 10.4
    Thank you

    Do the following:
    Extended Hard Drive Preparation
    1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process will take 30 minutes to an hour or more depending upon the drive size.
    Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.

    If you refer to this

    then they have an issue with mac version.
    At a first glance, their website is optimized for Windows only, it displays badly in Safari, perhaps it would be better in Firefox or other browser.

  • Folder problems on external drive, not showing correct file size

    I've run across a strange problem. I'm media managing for a tv show, meaning I'm offloading video from CF cards onto 2 external drives, one is a Drobo Raid (set up for backup) and another is a Lacie rugged drive. After copying the media to both drives, the folder I copy will match, but sometimes as I drill upward in my folder structure, suddenly the file sizes will not match. To be more clear: 2 folders will show differing file sizes, but inside that folder is only another folder,nothing else, which matches across the drives. I've shown all files in finder and there's no hidden files, though sometimes I see the ds_store files are different sizes (8k vs 16k), but that's not always the case. Sometimes if I simply create a new folder and move it's contents into it I can get the folders to match, but sometimes that doesn't work. It's part of my workflow to show that these copies match exactly via screenshots, and although the most important folder (the direct folder holding the footage) always matches, these folder problems are super frustrating as it's not constant, and any workarounds also work inconsistantly.
    I had an accidental disconnect of the Drobo one time, and although none of the data seems to have any problem, I fear it's done something to the directory. The rugged drive is swapped out every few days and the problem seems to be on the Drobo. Because the nature of the data is pretty important, I'm afraid to just try messing around with repairing or other software solutions unless I know it's super safe and won't harm the data.
    I'm at a loss as to what's causing it and at the very least how to avoid it cropping up. Any help or insight would be appreciated!

    I had the same problem with my iMac, first I repaired the disk, then I ejected the disk, restarted, and then reinserted the USB in a different port.  All of my files magically showed up.  I don't know what caused the error but it has been working fine since. 

  • Problem with USB drive not writing/freezing on unmount.

    I have a sandisk cruzer blade USB drive, which I have used for the past hours extensively. At one point, I couldn't manage to write data to it. It acted like it had, but it didn't, as it silently remounted as readonly. I solved this by remounting as rw and retried.
    Now, when using the same drive, after writing around 2 GiB worth of data to it (creating files), and attempting to unmount, the unmount command freezes for a long period of time. I check dmesg and it says its frozen. So I open up another tab to try and rescue the writes I made by typing sync. This also freezes and generates dmesg messages.
    As I'm typing this the commands seemed to have succeeded, but I'm wondering, what causes these problems? Is the problem known?
    dmesg output:

  • Problems swapping hard drive on mac book pro

    Is there a way to safely loosen the screws on the bracket holding the hard drive in place on a mac book pro 17 inch? I've got one loose, but the other one simply won't budge and the head is starting to strip. the amount of downward force I'm having to exert to try to get it to move seems excessive to the point of dangerous to me. i'm using a Philips 00 screwdriver which is the correct tool, I believe, but I just  cannot shift it. given that Apple say this is a user replaceable part, there must be an easy wy to do it, but all I can see me doing is more damage and being stuck with a captive screw that no one can move. Any tips  gratefully received.

    A 00 Phillips head screw driver is the correct size.  Is your driver the type where the tip of the handle allows it to be stationary while you turn the driver?  Apply a tiny bit of penetrating oil (Croil, if you can get it) and let sit after a few taps with a hammer on the screw driver set in the fastener.  Make certain that the screw driver is perpendicular and apply pressure.  Use a small Vise Grip on the handle if necessary.  And remember, Righty Tighty, Lefty Loosey.
    Ciao.
    A thought that may entail some risk if not done judiciously: use a soldering iron with a thin tip and heat up the fastener after applying the penetrating oil.

  • Is iPhoto '09 compatible with a NAS drive (non mac OS formatted)

    Since I upgraded to iPhoto '09 (8.0.2) iPhoto freezes at opening (empty window with spinning wheel).
    This happens with a huge (10K photos, 50GB) library on a RAID server stardom raidon SL3620-2S-LB2 under linux formatted as ext 2 and connected as a NAS (via gigabit ethernet)
    The same iphoto library on the macintosh HD drive is working fine.
    A small iphoto library is working fine on both the macintosh HD drive and the NAS.
    For info:
    I am not a designer playing with fonts.
    After I upgraded to iPhoto '09 from the DVD, it converted my library and I started to look at the animation which crashed in the middle (face recognition was running in the background).
    Any attempt to restart iPhoto failed (empty window with spinning wheel).
    Then I downloaded the last version of iPhoto.
    I restarted from a clean copy of the iPhoto library.=>Same failure.
    I try to rebuild everything (except the database which was not an option).=> same failre

    With the understanding that iLife '09 is not compatible with non Mac-OS extended disc (it was almost OK with iLife'08), I have applied the following workaround solution:
    1/ I have created a new virtual disk formatted as Mac-Os extended: using disk utility, new image; name=myVirtualDisc, size= more than you current file size, volume format= mac os extended, image format=sparse (faible densité in french) note: (sparsebundle was not possible / necessary for me),
    2/ whenever you want to use it, you have double click on the file named myVirtualDisc. It mounts as a disc appearing on the upper part of the left pane.
    3/ copy the file in the disc
    4/double click on the file name the first time you use it so that iPhoto knows where it is.
    5/ enjoy
    6/if latter you want to resize the maximum size, as it is a sparse image, you can do it after you have ejected the disc and using again Disk utility. Note that a sparse image only takes the place necessary on your disc (based on its content) and not as declared at the time of the creation (which is the maximum until which it can physicaly grow).
    Disclaimer
    - it worked at the first attempt but
    - I got a disk corruption which was detectable but not correctable by Disk utility. I had to create a new virtual disk and transfer the file. After that the faces were no more appearing on the corkboard, I had to delete the face databases inside the package to re-initialise the face recognition process (see separate discussion about this).
    QUESTION to experts:
    is a sparse image a reliable solution? in other word was it an unlucky / uncorrelated coincidence?

  • External Drive Format - Mac Extended vs Fat32

    Hi
    There seems to be a general consensus that if you are saving iMovie projects to an external hard disk, the format must be Mac Extended (Journaled).
    There is an Apple support article from July 2003 saying that this is the case.
    However I have experimented, testing an imovie 6 project saved on both a Mac Extended partition and a Fat32 partition on my external drive.
    Both appear to run perfectly.
    Does anyone know whether the article / idea that iMovie needs Mac Extended format is out of date? Has subsequent releases of iMovie fixed the issue with using Fat32?
    Any experiences/thoughts anyone? I'd ideally prefer to keep my external as all Fat32 seeing as I want to swap files with my PC.....

    Why not partition the drive, one partition Mac OS Extended, one partition Fat32, as suggested in another thread?
    BTW, I wouldn't rely on your experience storing an iMovie project on a Fat32 drive to prove much of anything. If Apple says not to use it, I wouldn't use it. There's no way any one of us can test all the conditions that can and will arrise.
    One such condition, if memory serves, is that large clips — longer than 20 minutes — do not import correctly with Fat32. Something about a 4GB limit, if I recall. Users have reported other problems too. A search for "Fat32" in the iMovie forums should reveal several.

  • Yosemite crashed and my default boot drive is not visible

    I installed Yosemite with no problems, but while playing a game my 2009 Mac Pro crashed, which has never happened before. On reboot, it now seems to be booting from a secondary internal drive, which is essentially a clean 10.9 install. My SSD, which was my main drive, is no longer visible. It can't be seen from Disk Warrior 4.4, Disk Utility, or under the About this Mac system report.
    I have a Time Machine backup, on an external drive, from this afternoon, but it is not configure for the "new" boot drive. I am not sure how to use it to overwrite this drive. Maybe I should have posted this in the Time Machine forum, but I thought the Yosemite crash was the important point.
    Any Ideas on how I can recover my old drive or restore my backup on my secondary drive?

    I am up and running again. I removed my SSD and replaced it with an older drive that I had removed when I put the SSD in. The old drive could not be seen on reboot, but the SSD could be seen through a USB port. I assumed this meant my SATA controller had a problem. I decided to reinstall the SSD in the empty optical drive bay. Int he process I had to remove the 2 OS X hard drives, the one that booted in bay 2, and the one that could not be seen in bay 1. I also reinstalled those 2 drives. Bay 3 and 4 have windows drives.
    Upon booting all three OS X drives could be seen. After giving them all unique names, I was able to boot back into Yosemite. I have no idea what was wrong. Was it the OS, the drive, the SATA controller? All seem to be working now.
    Lets see what happens when I try to play my game again!

  • Since upgrading my Macbook pro with Yosemite, I have problem with my Xerox Work Centre 3045 - the printer works normally but it does not recognise the scanner, can you help with this?

    Since upgrading my Mac book pro with Yosemite, I have problems with my Xerox Work Centre 3045 printer. The printer works normally but it does not recognise scanner, I can not scan anything. Can you help?

    Open Disk Utility and select your hard drive, then Repair Permissions, it will probably return a very large number of errors, primarily printer and library errors, so run it a second time.  Then restart the MacBook Pro.  If it still will not scan, try using Image Capture from Finder > Applications and see if that will work.  If not, contact Xerox about updated drivers.

  • USB thumb drive not mounting... hardware or software problem?

    I have two systems I'm working with. The first is a MacBook, running 10.5.6 (also Parallels 4 for WinXP). I have no problems here.
    The problematic system is a MacPro, running 10.5.6 (and Parallels 4 for WinXP).
    Symptoms:
    All USB ports function (sort of). I can plug my keyboard in to any port and they work. If I plug a thumb drive in (to any port), it periodically flashes, but never mounts, nor is it visible in Disk Utility or System Profiler.
    If I start Parallels with the thumb drive inserted. It asks me what I want to do with the device, and I can tell it to mount on the mac, and it does. If Parallels is already started, then I insert the thumb drive, nothing (Mac OS or Parallels) notices it was inserted.
    If I boot Windows directly, then insert the thumb drive, it tells me the port is not a high-speed port, but will still mount the device.
    Finally, again, I have no problems with this thumb drive on my MacBook.

    Roger
    This may be sorted out in the Preferences for Parallel. In the configuration editor>usb option>connection options.
    With parallels running does it see the usb in the menu under devices when you plug it in?

    Both Lion and Mountain Lion are downloadable from the Apple Store:

    The OSs will get more resource hungry the higher you go.
