Startup Disk not recognizing Windows disk

I had a working Snow Leopard installation with Windows XP on a separate disk. Bootcamp worked correctly. I reinstalled Snow Leopard on the primary disk and now Startup Disk will not recognize the Windows disk, although holding down Option at startup recognizes both disks and using Startup Disk on Windows recognizes the OSX partition.
Any ideas on how to solve this?
BTW, I do not have any NTFS software running on under OSX.
Thanks,
Mitch

I'm having the same issue except with Windows 7. Mac OS X refuses to see my NTFS partition.

  • Macbook Pro not recognizing Windows 7 RC 32-bit disk

    I'm trying to install Windows 7 RC on my Macbook Pro but it's not recognizing the disk. Does anyone know why this is?

    ucbound,
    I replied in my post to your same question as well.
    Are you using Boot Camp Assistant to set-up for a clean install of Windows 7 RC:
    Start Boot Camp > Create Windows partition > insert Windows DVD > click 'Continue' after DVD icon shows on desktop?
    Or are you receiving the error message after clicking 'Continue' in Boot Camp Assistant?
    Others here are more experienced with the MacBook series so hopefully they will chime in at some point if it is an in-depth issue / resolution here.

  • Hard drive not recognized in disk utility

    I'm trying to replace the hard drive in my MacBook Pro , the old hard drive was not recognized in disk utilities after the computer crashed .After installing a new hard drive and booting from the original Mac OS install DVD,( leopard?) the new hard drive is not recognized either ? Help

    It may be the internal connecting cable that is the problem.  If you can install the new HDD in an enclosure, connect it to the MBP, then see if you recognize it using the OSX installation disk.  If so, the internal connector should be replaced.
    Ciao.

  • ---   disk not recognized by this computer  ----

    I have the G4 tower with a dvd burner, and I recently
    bought a floppy drive read/write. [t-max? external teac]
    Files which were prior saved onto floppy get an error msg:
    ' disk not recognized by this computer ' 'format now? '
    these were claris works files, saved via apple IIg onto
    apple formatted 1.4 mb disks, which are now un readable.
    suggestions ?
    oh .. the unit IS working OK to save jpegs, claris 5 files now.. on my current system.....
    but floppys previously [1990's] formatted are not readable.

    Reader Gerrie E. Cooper has a stash of old floppies that contain fonts from Adobe, Agfa, and other companies. It’s bad enough that the fonts are stored on this prehistoric media, but said media is of the 800KB variety. He wonders what course to take.
    I’m afraid that the answer is to find an old Mac (an SE on up to a beige Power Mac G3 will do the trick), insert the floppies into that Mac’s drive, create disk images of the floppies, and then copy the images to the current Mac. Third-party USB floppy drives support 1.4MB HD floppies but not double-density 800KB disks.

  • Windows 7 Pro Install disk not recognized

    Hi everyone,
    I have checked this forum and found several discussions regarding this topic but no clear solution.  I am trying to create a Windows 7 Boot Camp partition on my late 2008 MacBook Pro.  I have a DVD drive with the following specs:
    MATSHITADVD-R   UJ-868:
      Capacity: 3.22 GB (3224993792 bytes)
      Model: MATSHITADVD-R   UJ-868                 
      Revision: KB19   
      Serial Number: dE018A75
    My problem is that my drive/computer will not recognize the disk.  I have several times inserted the autentic Windows 7 Pro install disc that I puchased from Microsoft, only to get the following error in Boot Camp: Install Disk Could Not Be Found
    I should mention that I have installed windows with this install disc on this computer with the existing DVD drive before. I have no idea why it is not working this time!
    Thanks in advance for any help or suggestions!

    Have you tried to install without the driver? then install the boot camp drivers after Windows has been installed.

  • Boot device not found. "Hard disk not exist". windows not booting

    Product: HP G72-110SA
    OS: Win7
    two days ago, I was installing updates on my computer and when it was about to restart, it froze. After waiting for 10 minutes, I had to turn it off by pressing the off button. From then on, the computer turns on but shows a message "Boot device not found".
    I have tried all the BIOS tests that I could find on the net for the hard disk, eg: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01443465&tmp_task=solveCategory&cc=uk&dlc=en&la...
    This gives me a "Hard disk not exist" error. I tried resetting the BIOS, that didn't work. I tried taking out and putting back in the battery, the memory and the hard disk. Still no luck.
    I then booted ubuntu from cd on the computer. It works just fine, including the internet etc EXCEPT the HDD is still not detected.
    I had some pretty important stuff and no back up, so would appreciate if someone can help me get back the data. If not, even if I know its just a HDD failure and not a motherboard/BIOS problem, it will be a relief as its probably fixable.
    Thanks

    Hi there ,
    Thank you for visiting the HP Support Forums and Welcome! This is a great site to get answers and ask questions. I would be happy to assist you. As there are many models of HP Notebooks, I would need the model number. (How Do I Find My Model Number or Product Number?) When I went to www.hp.com/go/techcenter/startup, it gave me documentation and troubleshooting steps to follow. One of the documents it provided is called Hard Disk Error Displays before the Computer Starts. NOTE: I recommend at this point you make an immediate backup of all important data and files. Here are instructions on how to Backing Up Your Files (Windows 8). Please follow the troubleshooting steps provided, re-post with the results of the troubleshooting in detail. Thank you.

  • Old (Really Old) Apple Files /Disks Not Recognized by Current Computers

    This has doubtless been asked before, but I could not find anything in the 6 pages of recent postings under "Older Apple Products."
    How can I access old Applewriter and Clarisworks / Appleworks word processing documents and save in an updated format? I was able to retrieve most old documents by going back to OS 9 and use Appleworks 5, then use OS X and Appleworks 6.2.9 to save in newer format. However, some very old documents are on 3.5 disks that are not recognized by my current Apple computers, or my Windows XP laptop.

    You appear to be talking about two separate issues—translating the files from an earlier version of ClarisWorks/AppleWorks to the AW 6 file format, and retrieving the old files from disks that cannot be read by your current machines.
    You have solved the first issue—If you can access the files, you are able to open them with AW 5, Save them, then open the saved copies with AW 6.
    For the second issue, you are going to need a Mac with a 3.5" drive that is capable of reading the disks on which the files are stored.
    3.5" floppy disks came in three varieties. From oldest to newest, these were Single sided (400 KB. These had a single hole, near the top edge of the case, with a write protect slider used to prevent data from being written to the disk), Double sided (same, 800 KB, with two holes, one of which had the write protect slider) and High Density (double sided, 1.44 MB, identifiable by stylized "HD" molded into case). The early Macs came with a 400 KB drive. The last of the pre-iMac versions had HD drives. When the original iMacs(with no floppy drive) were introduced, some third parties offered external HD floppy drives that plugged into the new USB slot. Note that pre-iMac machines did not include USB.
    Once you have a machine with a floppy drive that you can use to read the files, you can collect the files on that machine's hard drive. From there you can move the files to your current machine, open and save them with AW 6.
    Moving the files from one machine to the other can be done via ethernet, email, or sneakernet A or B.
    A: Burn the files to a CD. Copy from the Cd to your current machine.
    B: Save the files to a Flash drive. Copy then to the new machine.

  • MacBook Pro 3,1   2007 disk not recognized at install

    Hi,
    I installed SnowLeopard on two of my Macs without problem. Trying the same on my MacBook Pro 3,1 2007 with a 320GB drive gives me a headache. I erased the volume completely, started up from the install-DVD and clicked install. However, the installer did not recognize the volume and did not list it in the selection window. Even running DiskWarrior on the empty volume did not change things. Several attempts to no avail.
    The earlier system was 10.5.8 with the latest updates.
    I also notice that the Installer DVD takes a long time to start up and to initialize the installer.
    Does anybody have an idea why the volume would not be recognized?

    Hi donv: I repartitioned, rechecked with DU, even ran a hardware test, still not recognizing the HDD from within the (family pack) installer.
    Restoring 10.5.8 works and the machine boots just fine. I am at a loss.
    The disk is a WDC WD3200BEVT-22ZCT0. Could the disk be a problem? A year ago a certified technician replaced the original disk with this one.

  • Installation Failure: Audition 3 disk not recognized

    When I place the Audition 3 disk into my CD/DVD drive to install, it whirrs a bit then...nothing.
    When I look at the CD/DVD drive using windows explorer it displays a file view of D: (my CD/DVD drive) with nothing in its file listing. The view of the listing of files thats supposed to be on the CD is a complete blank. I have View hidden files in XP turned on.
    My system:
    Cd/DVD drive by Memorex dvd 16+ dl4rwid2. Drivers are up to date
    Win XP Sp3
    I've tried placing the media in my laptop and it reads the disk ok (but that's a vista machine). So I know the Audition 3 disk seems to be ok.
    Coming back to the XP machine, I have successfully installed many other programs INCLUDING Photoshop, and just yesterday: Illustrator -- all from the same drive. Audio CDs and Video DVDs play no problem. As a matter of fact, I have been able to install the Loopology disk in the Audition 3 package! I've called Adobe support -- they were a big help: "talk to the hardware manufacturer". Sheesh.
    I've even tried to copy the contents of the Audition 3 disk to the desktop usig the DOS prompt but it returns and error "the device is not ready". That's the same error you'd expect to see if there was no media in the drive. So it seems like the system does not recognize the Audition 3 installation disk at all.
    The Audition 3 installation disk is the ONLY disk my system has EVER not been able to read.
    Has anyone else seen this installation behavior with the Memorex dvd 16+ dl4rwid2?
    Any ideas on how to fix this?
    Thanks for the help.
    Mark

    Here is how I solved this. It was really quite simple once I thought through the problem.
    I took the disk to my laptop (which could recognize the disk, but where I did not want to install the app) and copied all the files into a subdir (called it TEMP) on the Laptops desktop. (the disk buzzed/vibrated more than usual during this task, so I guess it was out of balance. That's why it probably failed in my desktop drive)
    Anyway, I then burned the files in the Temp subdir to a blank CD on the laptop...took the newly created CD over to the desktop machine (that was not recognizing the original Audition 3 disk), put the newly created CD into its the desktops drive, and poof...it worked! Installation proceeded normally with the newly created CD.
    Cheers!

  • Hard crash now hard drive not recognized in disk utility.

    During a virus scan the Macbook froze up now the computer does not seem to be accessing the hard drive. Tried to reinstall Leopard but the internal hard drive is not recognized (same is true when we tried to use Disk Utility). It will not start in safe mode either. Does this sound like a fried hard drive or maybe a corrupted drive that might be repairable with DiskWarrior? Any thoughts would be appreciated.

    If the A/V you were using was Norton/Symantec, the drive may be OK. Norton is a virus.
    Burn a Ununtu CD and see if you can boot into it and look at the drive before giving up on it.

  • Macbook Pro Will Not Boot Windows Disk

    I have a late 08 (or early 09) Unibody Macbook Pro 2.53Ghz. I start the Bootcamp Assistant and successfully create my Windows partition. When I restart with the Windows 7 disk, I get a blinking cursor for 1 second then it goes to a black screen and never leaves. I have tried several different Windows 7 disks with the same result. I have even tried booting from a Windows Vista, Windows XP and even a Ubuntu disk all with the same result, stuck at a black screen.
    I took the hard drive out of this mac and put it into my wife's older Macbook pro, and it booted off the Windows 7 disk and completed the install to the drive with no issues. I then put the hard drive back into my Macbook Pro and get the same black screen when trying to start the Windows partition, and still have the same problem that it will not boot from any other OS disk be it Windows or Ubuntu. It boots from OS X DVDs without a problem.
    Also several months ago I had a Windows XP installation on this computer with no issues. I wiped it just before going to Snow Leopard.
    Any clue as to what is going on here?

    What is really odd is if I take my hard drive out of my Unibody Macbook Pro and put it into my wife's non-unibody Macbook Pro, it boots the Windows partition with no problem (Remembering I previously swapped these hard drives to complete the Windows installation to my hard drive). Seeing as the disk boots on her machine fine and not in mine, and my Windows cds (DVDs) boot fine on hers and not on mine, it seems to me it's something specific about my machine, but I can't imagine what it is.

  • Disk Utility not recognizing connected disks half the time

    About half the time i run Disk Utility all i get is the Disk Utility window that's blank on the left side where my connected drives should be and in the main area of the DU window is the message "Gathering disk information" will a spinning wheel type thing under it. The only way i can quit DU is by forcing a quit. I don't have any idea why this happens so much. I've run repair permissions and repair disk from the install disk. No problems detected.
    Any ideas?
    thx
    lenn

    disk utility can only repair directly attached drives. it can not work on network drives like Time Capsule. but you can try repairing the sparse bundle itself. drag it to disk utility's left pane, select it there and choose "repair disk".

  • Equium A210-1C4 not recognizing optical disk drive

    I have a Equium A210-1C4 which will not recognise the odd.
    The drive has power and spins disks but does not appear as a drive in MY COMPUTER.
    It also is not recognised in the Bios.
    I have updated the Bios and tried to install the firmware but get message that the drive is not found.
    I have tried is in another computer and it works fine.
    Has anyone had similar problems and is there a solution?
    Many thanks

    > I have tried is in another computer and it works fine.
    You have tested optical disc drive in other computer?
    Anyway, if the ODD is not recognized in BIOS Im afraid ODD controller is defective. It is mainboard issue so there is no some kind of easy solution.
    I don't think you can do much about that except to exchange the mainboard.

  • [SOLVED]Hard Disk not recognized when installing

    Hey all, I'm just starting with Arch and I've had some trouble installing it on my Acer netbook.
    My first installation went well except that I had forgot to download the wireless tools so I decided to do a fresh install as I had no access to a wired connection at the time.  The second installation attempt must have had some error on my part as Arch failed to start after selecting it from Grub, saying that the kernel was not available/not recognized.
    Now my subsequent attempts at installing have failed because the hard disk is not recognized when running either cgdisk or cfdisk.  Instead of showing my hard drive partitions after running
    cfdisk /dev/sda
    it shows my usb drive. If I instead use
    cgdisk /dev/sda
    it displays an error saying that the disk is damaged or not recognized.  When I first saw this I thought my disk was failing, so I tried #! to see if it would show the same error, but it was able to recognize the entire disk and install correctly.  Now, even after having the entire disk formatted as ext4 with #! installed, cgdisk is still giving me the same error about a damaged disk.
    Am I doing something incorrectly or is there a fix for this?  I haven't been able to find any information about this after a good while of searching.
    Thanks for your help.

    If you mean by trashing the USB flash drive, that it will delete all data and partitions on the selected drive it is correct, because:
    dd if=/dev/zero of=/dev/$disk bs=4096 count=1
    - this will delete all partition-table data
    sgdisk -o /dev/$disk
    - this will clear out all data. This includes GPT header data, all partition definitions, and the protective MBR.
    /dev/$disk
    - this will make you enter ncurses-based GUID partition table (GPT) manipulator, where you can create new partitions
    You should only do this if you are certain of what disk it is.
    Now if when you said this, you were meaning it will became broken, then it may be a special kind of usb drive because i've donne it many times and i've not broken any.
    srs5694 wrote:My guess is that either your hard disk has become /dev/sdb (this can happen in some cases; disk identifiers aren't really fixed) or you're missing a driver for your hard disk controller because you've booted a different kernel or a different initrd file. Another possibility is that there's a hardware fault -- probably a loose cable -- that's preventing the kernel from seeing the disk.
    If the usb drive is not where you installed arch, then you need to find if there are more recognized drives:
    lsblk | grep disk
    And see the uuid of the root partition you want, and add it to your bootloader boot line:
    blkid /dev/sdxx

  • Disk not recognized

    Various people have similar postings on this but not QUITE the same...
    I login and I receive the message "The disk you inserted was not recognized..."
    I have the choice to eject, ignore or initialise. If I go to disk utility it is described as a 1mb config disk in the left hand column with the following descriptions:
    Disk Description : Config Disk Media Total Capacity : 1 MB (1,048,576 Bytes)
    Connection Bus : SCSI Write Status : Read/Write
    Connection Type : External S.M.A.R.T. Status : Not Supported
    Connection ID : SCSI Target ID 1, Logical Unit 0 Partition Map Scheme : Unformatted
    I have an e sata card (lacie) which works fine, and a Kona card which also works, plus an extra internal hard drive... all drives are initialized and all seem to work well. Ejecting the disk seems to make no difference...
    But what is it? Any ideas anyone?
    Many thanks

    When I set up Time Capsule to back up the 2 computers in wireless mode, I can only see one disk drive - not 2. Any ideas why the second disk drive is not seen by Time Capsule?
    What are the 2 drives connected to?
    Just to be clear... On the first MacBook you would go to System Preferences-> Time Machine preference pane and select the Time Capsule as the destination. Then on the second MacBook you would do the same. Is this what you did?
