Hard disk partition area inaccessable

Hello,
I have a 15 GB Quantum HDD. I tried to Install Solaris and it created a swap partition of size 720 MB on it. The installation failed due to some reason afterwards. BUT that partition is now INACCESSABLE. I have tried low level disk formating utilities, i have tried Quantum Disk Manager "Zero fill", I have tried to do every thing but every thing results in a total accessable size of 14300 MB. Where is my 720 MB area. THe badluck is that it was created in the primary partion area of the hard disk. Now Iwant to install linux as well as windows on my harddisk but there is not enough primary partion area to create necessary partitions. Can some one tell me how to retrieve this area taken over by solaris ???

Hi,
15 GB Harddisk space is FORMATTED capacity. I have checked BIOS settings. Plus I have tried to format it low-level on my P-I and P-II machines as well. But not successful. This problem occured since I tried to Install Solaris on it. I tried to Install SOLARIS again and it shows that partition as a non-DOS partition. I happily deleted that partition from there but after restart it again vanished.
What should I do ? I have also written to Maxtor people but still haven't got a reply.

  • Hard disk partition not showing up during window 7 install

    STOP - 0x00000116 error . I
    want to install fresh OS from usb stick but the hard disk partition is not showing up. Only USB stick is getting detected.
    Please help .. I have an interview and I need to fix this issue asap.

    Hi there,
    Welcome to the HP Support Forums! It is a great place to find the help you need, both from other users, HP experts and other support personnel.
    I understand that your hard drive is not showing up, presumably as a bootable partition. I am happy to help, but I need a bit more clarification of your problem. You mention a 0x00000116 error as well, which is normally part of a Blue Screen of Death. Does this happen regularly as well, or is that the real complaint, that you are getting the 0x code and a BLue Screen on startup?
    That particular code is generally associated with a video driver problem.
    Is the hard drive you are trying to install to, a new replacement hard drive or the original hard drive?
    If you try to boot up the system, what error do you see?
    Are there any repeating flashing LED patterns, or beeping patterns?
    Assuming this is your original installed hard drive, did you try the recovery manager for the drive?

  • Can't erase anything on an external hard disk partition of bootable backup ____error message -50 "Error in user parameter"

    I am using MACOSX 10.6
    The data on the disk partition  on my Iomega 2Tb external hard disk drive (labeled "Bootable Backup") was written by Carbon Copy Cloner (CCC ver. 3.37)
    I have had problems with overwriting this using CCC, and I have also had troubles changeing the data on my "Versioned Backup"  partition, using either CrashPlan or CCC
    A third partition that was virgin ("Half-Tb Volume") on the same external disk drive, however, DID accept the latest CCC bootable backup of my Macintosh HD...which is the reason I want to recover rthe space on the first bootable backup partition.
    I have not found any links to this error using Google search, apart from the definition.
    Anyone

    Do a backup using Time Machine or a clone. Then boot into the Recovery Volume (command - R) on a restart. Run Disk Utility Repair disk. If it can't repair the disk, then select the erase tab and reformat using Mac OS Extended (Journaled). Also click the Option button and select GUID. When complete, reboot normally and restore your data.

  • Hard disks, partitions and Mac Pro

    Hi all,
    I'm new to the Mac Pro and am migrating from a Windows environment, I have used a iBook for the past 6 months and this is the reason for totally migrating to a Mac Desktop.
    I have spent half a day on browsing the forum here, very confusing I must say but then again I add that I am an absolute a-technical person.
    I have a few questions on storage which I hope might get answered here;
    My Hardware:
    I am about to order a 2,66ghz Mac Pro, 4GB Ram, XP1900 and a 160Gb hard disk will will be replaced as soon as the Mac Pro enters my dwelling.
    My Work Environment:
    Apart from the basic office things, Internet, Mail and such I will use the mac Pro 90% for Imaging purposes. Most used applications:
    - CS2
    - Aperture
    - Adobe Lightroom
    as well as a number of add-ons like HDR programs, Noise programs, RAW converters etc.
    I am a Photographer working with Mid-format and Standard format images, which in some case, like when using HDR can reach sizes of well over 150-200Mb per image!
    Useually the image size of a 16bit mid-format tiff are around 70MB.
    Now for the question, how to configure the best possible HD setup.
    I will use WinXP, which I would like to run on a seperate partition/disk
    I need a schratch disk for CS2
    I need roughly 500GB of intermediate storage for imgaes before the periodically get back-up to external hard disk.
    So I was thinking the following, and this only based upon how I used my Win Environment:
    150GB Raptor as start-up disk and location for programs and OSX as well as basic documents and files
    76GB Raptor as Scratchdisk
    500GB as WinXp disk (30%) and rest as storage for Image cataloging system (mainly normal sized Jpegs)
    750GB as Image tank
    I have the Raptors, but don't have to use them if a better solution comes out. Since I will be using my Win pc until everythink works satisfactory on the Mac...
    some remarks:
    I have red about raid, both 0 and 1 seem interesting but I will loose out on disk space possibilities, and will be forced to work with external drives again, which I don't like... but if push comes to shove I will do that.
    sorry for the information overload, and maybe all points have been answered in other threads before, but whilst browsing through hundreds of threads I couldn't see the forest becasue of the trees anymore.
    One last comment, I make my living with photography so a good setup is of vital importance ....
    Kindest regards, and many thanks in advance

    Hi all,
    Hi,
    Now for the question, how to configure the best
    possible HD setup.
    IMO; use a 3 drive RAID 0 for your boot, application, and
    data partition - my style would be all in one big partition
    and just segragate stuff with folders. I would then add 2
    USB or FireWire drives. One for backing up your system
    and one for the windows XP if you just have to have windows
    running on your MacPro. They don't run at the same time you
    know - like on Amiga where MacOS, Windows, and AmigaOS all
    multitasked together in shared memory space simultainiously.
    As such my opinion is that it's better to keep your WinTel
    box on a KBM switch and LAN the two together.
    I will use WinXP, which I would like to run on a
    seperate partition/disk
    I need a schratch disk for CS2
    With a 3 drive RAID your disk I/O is between 3 and 20 times
    the speed of a single drive setup so separate cache drive
    isn't really advantagious. Click on the link below and
    scroll down to the Drive Test area:
    http://db.xbench.com/merge.xhtml?doc1=199338&doc2=195252
    Both are my profiles. One with a single drive, and one
    with a 3-drive raid. No other differences.
    I need roughly 500GB of intermediate storage for
    imgaes before the periodically get back-up to
    external hard disk.
    So I was thinking the following, and this only based
    upon how I used my Win Environment:
    150GB Raptor as start-up disk and location for
    programs and OSX as well as basic documents and
    files
    76GB Raptor as Scratchdisk
    500GB as WinXp disk (30%) and rest as storage for
    Image cataloging system (mainly normal sized Jpegs)
    750GB as Image tank
    I have the Raptors, but don't have to use them if a
    better solution comes out. Since I will be using my
    Win pc until everythink works satisfactory on the
    Mac...
    IMO the Raptors are overpriced. If it were me I would sell
    them. I think the two together will pay for all three 320
    or 300 gig RAID drives. I did some research regarding which
    drives are good in a Mac RAID environment and I ended up
    going for the the MaxLine Maxtor drives (even though I hate
    Maxtor usually). So far I'm very happy with them and the
    fact that they are like one of the most inexpensive drives
    you can get didn't hurt either.
    I think that if a person REALLY needs the speed offered by
    Raptor drives and is willing to pay the difference for it
    then they should just get a dedicated RAID card which offers
    even more of a speed increase!!!
    some remarks:
    I have red about raid, both 0 and 1 seem interesting
    but I will loose out on disk space possibilities, and
    will be forced to work with external drives again,
    which I don't like... but if push comes to shove I
    will do that.
    You don't lose any space if you use just RAID 0. If there
    are three 300gig HDs that format individually to 260gig
    each then in a RAID 0 configuration you would have 780gigs.

  • Hard disk Partition is suddenly lost

    I am using T500 with Windows 7 installed on it.
    Facing the issue of all the partitions except C: getting lost suddenly along with all the data. This is happening the second time in a week. I cannot see the partitions in the explorer and even the disk management utility shows everything apart from C: as free space.  
    Any help on why this is happening would be appreciated. It is frustrating as I not only lose my data but have to spend valuable time to restore my environ for further work.

  • Hard disk partition as a neutral "go-in-between" MacOS and WinXP?

    Hi gurus,
    I have a MacBook with a 500GB hard drive partitioned between Mac (400GB) and bootcamp (NTFS, 100GB, running Windows XP). Unfortunately I am using old software which does not exist for a Mac, written under Win 95 and operating an external controller unit. I then analyze the incoming data with MatLab and ArcGIS, but need to do further data processing under Mac environment (further statistical analyses, image editing and writing up the results).
    I was advised to use bootcamp to speed up the PC performance with GIS and MatLab because the data is quite "heavy" (memory and time consuming operations on rasters some of which are 100's of MB).
    I find myself switching frequently between operating systems, accessing my data on a flash or an external backup drive. Last week when my backup disk crashed logically after an improper ejection, I realized that I eject and re-eject it too often now. So basically I would like to have an "internal" go-in-between partition, where I can save and read data from both systems exactly as I do from a flash stick.
    Is that possible in any way? I tried to resize the mac partition and add a FAT one, but this doesn't seem to work at all (googled the error, followed recommendations, no good). I have been told there is software which lets Win read Mac partition and vice versa, but I don't want the systems to interfere with each other. I just want a neutral piece of land where I can place some neutral data...
    Thanks,
    Benny

  • Hard disk partition issue and space issue

    Hello i was trying to do a partition on my hard disk on my macbook pro retina. Wen i go to disk utility and try it says i need to repair the disk. I used command r in reboot and repaired but still having issues. When i look at space i get two different space available on macintosh HD. Here are the pictures you will see the space available is different depending what i choose. I am confused. Any help is appreciated. Here are the pics.

    When you boot using Cmd-R, you're booting from a hidden Recovery Partition. That partition is using part of the space that is the size difference you're seeing between the Media line (upper picture) and the boot partition line. You can turn on the Debug Menu which shows the extra partitions using these directions.
    I'm not sure but I suspect the issue may be that your boot partition is encrypted.

  • Hard disk partition issue

    Dear
    I purchased Lenovo G580 one month before. The hard disk size is 750GB.The “C” itself 650GB. I tried to do the partition of250GB from Local disk C. After partition it shows unallocated space. But after that I could not make format for that unallocated Partition. During partitioning a pop up window shows that “The operation you selected will convert the selected basic disc to dynamic disc. If you convert the disk to dynamic, you will not be able to start installed operating systems from any volume on the disk (except the current boot volume). Are you sure you want to continue?”.
    If I press “yes” the popup window show that “Dynamic disks are not supported by this operating system or server configuration. Dynamic disks are not supported on clusters”.Please check and give me a solution. I am using Windows 7 Home premium . here i attached the photos.

    It may be formatted in some Windows format that Macs cannot use. If there’s nothing on the drive that you want to save, reformat it with a Mac-friendly format. http://computers.tutsplus.com/tutorials/how-to-format-your-macs-hard-drive--mac- 53986

  • I need to transfer all photos to an external hard drive. Many photos have been moved around or deleted from computer hard drive, but still have a very full hard disk. Are the photos with questionmarks in Lightroom still taking up hard disk space? I'm so l

    Hi folks,
    My hard disk is full. I already moved lots of photos from other folders on the hard disk to other external hard drives, so there are a lot of question marks in Lightroom. So, are those photos still taking up room on the computer hard disk? I want to move everything I have in Lightroom off of the computer to another external hard drive, in hopes that will free up space. I watched a tutorial, and read some things about it, but I need simple instructions please.

    I cannot find this 300GB "Backup" in the Finder, only in the Storage info when I check "About This Mac".
    You are probably using Time Machine to backup your MacBook Pro, right? Then the additional 300 GB could be local Time Machine snapshots.  Time Machine will write the hourly backups to the free space on your hard disk, if the backup drive is temporarily not connected. You do not see these local backups in the Finder, and MacOS will delete them, when you make a regular backup to Time Machine, or when you need the space for other data.
    See Pondini's page for more explanation:   What are Local Snapshots?   http://pondini.org/TM/FAQ.html
    I have restarted my computer, but the information remains the same. How do I reclaim the use of the 300GB? Why is it showing up as "Backups" when it used to indicate "Photos"? Are my photos safe on the external drive?
    You have tested the library on the external drive, and so your photos are save there.  
    The local TimeMachine snapshot probably now contains a backup of the moved library.  Try, if connecting your Time Machine drive will reduce the size of your local Time Machine snapshots.

  • Hard Disk Partition Error.

    good evening bro, iam tried as u mentioned n created new volume when i click finish after  finish new simple volume it showing "the operation you selected will convert the selected basic disk to dynamic disk. if u convert the disk to dynamic , u wil not b able to start installed operating system from any volume on the disk(except the current boot volume ). are you sure want to continue."
    yes or no
    so bro what should i do if i tried yes it showing "dynamic disk are not supported by this operating system or server config. dynamic disk are not supported on clusters. pls help me

    How many partitions are you trying to make? What are you trying to do? There is a limit to how many simple partitions you can have (4 I think).

  • Hard drive partitions are not showing in Startup DIsk

    My hard drive is partitioned into two volumes. HD1 & HD2 (Both 500 MB)
    I had Snow Leopard installed on one (HD2) and Mavericks istalled on the other.(HD1)
    Both volumes were visible in the Startup Disk option in System Preferences and I could restart from either.
    I upgraded the Mavericks istallation to Yosemite - worked OK.
    System Disk option showed both HD1 & HD2
    Restarted the Mac from HD2 in Snow Leopard mode - no probs.
    Then the problem started. I wanted to restart from HD1 in Yosemite mode.
    Went in System Preferences to Startup Disk option - HD1 did not show in the window - only HD2 (Snow Leopard) & Network Startup.
    Any ideas anyone? (Could be a bug?)

    When I restarted using Com+Opt+P+R it went into Yosemite mode with both volumes showing in Startup disk.
    Restarting with HD2 (Snow Leopard) gave me the same problem again.

  • Creating bootable external hard disk partition

    Apologies if I've missed a "how-to" for the following question.
    I have formatted & partitioned an external FW hard drive into 2 partitions using the GUID partition table which according to Disk Utility is the one to use for my purposes.
    I don't need to clone my internal disk, I just need to boot from an external but I'm drawing a blank. Need I use the Installer disk & can I select which volume to install to?
    OR
    Can I drag & drop my system folder from my internal? I hope I've posted this question in the right forum.
    Thanks!

    Yes. boot from the installer disc by restarting and holding down the "C" key, then you can select any available partition to perform the installation.
    OR
    Can I drag & drop my system folder from my internal? ...
    No, this will not maintain the proper file access permissions. There are copy utility programs that will allow you to backup portions of your Mac OS X disc, like Carbon Copy Cloner, Super Duper, etc, which will preserve the appropriate file access permissions.
    Since you don't want to clone the entire drive, your best option is to install from the DVD, so you don't have to worry about which portions to copy over to get a fully functional boot disc.
    Not all external drives will boot a Mac, the internal chipset in the enclosure must support booting the Mac, you may be able to install the OS, but when you try to boot it may fail. What type of external hard drive are you using, do you know for certain that the vendor claims that it will boot a Mac? (Mac-compatible doesn't always mean Mac-bootable)
