Partition with Disk Utility in 10.7, Lost All Data on Drive

All,
I partitioned a 2TB drive with DiskUtility.  Partition 1: 1.99TB, Paritition 2: 1GB.  Lost all data Partition 1.  Two years of family photos, videos, business communications and files, time machine backups, are gone.  What to do?
The solution I have so far: downloaded "Wondershare Data Recovery," followed instructions, it is scanning drive.  Does anyone else have any experience with capabale softwares to use for this purpose?  How about some professional data recovery centers accross the US where I can mail in my drive, and they do the rest?
In general, what do I do?
Stressed,
Sincerely,
A Man Made More Cautious

Partitioning a drive is a destructive process that erases everything on the drive.

  • Partition with Disk Utility?

    I just got a 500gb external drive that I want to partition. Disk Utility is supposed to be able to do this. The help file says "Click Partition" in the Disk Utility window. I see nothing in the window with "Partition" on it. A screen shot I've seen (from LaCie's hard drive manual) shows five buttons across the top of the window: First Aid, Erase, Partition, Raid, Restore, but my Disk Utility only has 4 buttons. The "Partition" button is not there.
    Any ideas what's up? This is crazy. What am I missing?
    I've clicked on the external drive icon along the left column but nothing pertaining to partitioning shows up.

    That is because you have your boot volume selected in the left hand column, select the Hard drive itself, the one with the Manufactory ID number. It should be at the very top.

  • Partitioning with disk utility

    hi there.. i wonder, can i partition my primary hard drive with disk utility live? (i mean not from the leopard dvd on boot) i want to create a new partition that would be less than the amount of free space i have, while running leopard (my mac os shouldn't be damaged i think), is that possible? and safe? thanx

    cukerko,
    If you have an Intel Mac, the answer is yes. Intel Macs must have internal drives that use the GUID Partition Map, and these can be dynamically partitioned and re-sized under Leopard's Disk Utility.
    It is relatively safe, but it is an action that modifies the drive at a low level. In other words, one would be foolish to attempt a re-partitioning or re-size without a good and current backup on hand. Provided you have such a backup, there's no reason not to create your partition.

  • Deleting a partition with Disk Utility

    I have 5 partitions on my external drive. One is corrupted to the extent that I can not erase it with D/U.
    I had tried to repair the partition with Disk Warrior, but it appears that would take many, many hours.
    Can I delete the partition without deleting the other four?
    Thanks for any help.

    No, Disk Utility will erase them all, use DW.

  • Difference between using bootcamp and building partitions with disk utility

    hy everybody,
    i successfully bought a mac (that was easy , installed windows 7 with bootcamp (quite easy) and now i 'd like to add linux also (considering ubuntu).
    before i try to do it with bootcamp i'd like to know what the impact could be...
    so i wonder; what does boot camp do and why shouldn't i do it manually with disk utility?
    all inputs are welcome
    cheers

    Why not start by filling out hardware in your profile .sig as it makes a difference.

  • Can't boot into Windows after splitting Mac partition with Disk Utility

    Hi everyone,
    I installed Windows 8 with BOOTCAMP, creating a large 871 GB partition with a smaller 127 GB partition for Windows. After installing Windows, I then went back to Disk Utility to shrink the Mac partition and add two new partitions, one for storage and another blank, hoping to use it to install Linux into one day.
    I did that, and now Windows doesn't boot. A Windows blue screen tells me I need to use the Windows DVD to repair it.
    I tried to use Disk Utility to delete the two new partitions I made and grow the Mac partition back to the max size of 871 GB. But it doesn't let me do this. The Disk Utility log doesn't report an error and thinks it worked but the partition stays the same size. However if I make the partition a little smaller, like 870 GB then it works. I'm wondering if the Recovery partition is hiding there and preventing me from fully expanding the Mac partition.
    What can I do?
    Here's what I get if I type in sudo gpt -r -vv show disk0:

    Kappy,
    I can boot into OS X just fine so if possible, I'd like to avoid reformatting everything. If you know of a way I can add more than 2 partitions with OS X and Boot Camp, please let me know. As far as I know, rEFInd can recognize more than two partitions, but I don't think it can edit partitions on a GPT / hybrid MBR system. Or am I wrong?

  • Can't partition with disk utility. Options greyed out

    Hi,
    Bought a used 4 TB Seagate drive, formatted it , checked the speed 150 MB/s read/write and made a partition. Apparently it worked perfect.
    However after this first partition the drive is behaving erratically. I can not modify partitions anymore nor delete them. Repair disk is not finding any problem either from the system or from the recovery partition.
    I am starting to believe the disk is damaged. Beside the partition problem the disk is behaving fine. Anyone please?

    Thanks. I already did. The disk whose partitions I can not modify is blank. It is the 3rd disk in the Mac pro. I formatted and created 2 partitions. But then I can not create more partitions nor delete them. I tried from the Recovery volume with the same result. Partition options remain greyed out.
    Beside that, if you look at the pictures, CCC 4TB and CCC 4TB2 are the same physical drive but seem to be different in disk utility. Is this disk damaged?

  • Dynamic resize of FAT32 partition with disk utility?

    Hi there.
    I have a 1TB external FAT32 drive with 300GB of data on it.
    I want to convert it to HFS+, but I know there's no easy way to do that.
    What I want to know is can I resize my FAT32 partition to 500MB and keep all the data?
    Then I'll move it to the new HFS+ 500MB partition, delete the original partition and resize the HFS+ partition.
    Or do I have no hope of that?
    Thanks
    Greg

    Greg,
    You're probably out of luck on this one. If the drive was partitioned and formatted by a PC (every drive has a partition map, whether there are multiple partitions or only one), it almost certainly has an "MBR" partition map. This would preclude a dynamic resizing by Disk Utility. It will need to be partitioned using either GUID (Intel) or APM (PPC).

  • Can't modify external hard drive partition with Disk Utility

    Hi,
    I have an external 750GB hard drive that I previously formatted as FAT 32 because I wanted to be able to plug it into Windows computers as well. I was not very thoughtful at the beginning and I just created one big 750GB partition. I currently have 450GB used and about 300GB free.
    I would like to create a new partition in the free space without losing the data I have in the disk, and format the new partition as Mac OS Extended to use it for Time Machine backups. Presumably Disk Utility can do it, but when I go to the "Partition" tab it says "This partition cannot be modified" and the "+" sign below it is grayed. Can anybody help me repartitioning my drive without losing my data?
    Thanks!!!

    That would likely be because the drive is partitioned MBR and not GUID. You cannot repartition an MBR partitioned drive on the fly. What you need is a drive that is partitioned using GUID (GPT) with on partition formatted for the Mac and the other formatted FAT32. But to do that you must start the drive from scratch:
    Drive Preparation
    1. Open Disk Utility in your Utilities folder.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
    4. Select the entire partition in the rectangle by clicking on it (the lines will turn darker blue) and click on the [+] Add button. The volume will be divided in two. Select each volume and resize as your require.
    5. Select one of the volumes you just created. Set the format type to Mac OS Extended (Journaled.) Click on the Erase button.
    6. Repeat Step 5 using MSDOS as the format type.
    This will work with any PC that understands the GPT partition scheme which is Vista and Windows 7. Otherwise, you should just leave the drive as it is and forgo using Time Machine or purchase another drive for Time Machine.

  • Partitioned with Disk Utility, during XP inst. desired partition N/A

    Basic computer info: Macbook Pro 3,1 Leopard 1.5.1
    I partitioned my computer into 4 separate partitions:
    MacSys - 25gb, journaled, extended
    LinSys - 12gb, journaled, extended
    WINSYS - 14.86gb, fat32
    HdaSys - 59.35gb, journaled, extended
    So, 1 partition per OS, and a commonly accessible partition.
    I used Disk Utility to do all this.
    The problem is that with my XP Home SP2 disk, the WINSYS drive does not show up. Instead, it shows 1 large conglomerate partition, I believe as unpartitioned space (Don't write that last bit in stone, this is from retrospect)
    What have I done wrong? I need some insight.
    Thanks in advance.

    Ahh thanks, now I understand.
    However, how can I have another partition for file storage/archiving which can be mountable from all other partitions? The njHdaSys would have problems, I would assume.
    Due to the GUID/MBR Hybrid issues, you need to change your GPT disk setup/cration to this:
    1: MacSys - 25gb, journaled, extended
    2: HdaSys - 59.35gb, FAT32
    3: WINSYS - 14.86gb, FAT32
    4: LinSys - 12gb, FAT32
    Then after using a tool that creates a hybrid MBR on your GPT disk (such as gptsync included with rEFIt or maybe some version of OSX's Disk Utility), your hybrid MBR (what Windows ONLY sees) will be:
    1: EFI Protected
    2: MacSys - 25gb, journaled, extended
    3: HdaSys - 59.35gb, FAT32
    4: WINSYS - 14.86gb, FAT32
    (with LinSys not accessible (to Windows) and showing up as 'unallocated space', which you can't ever touch under Windows or you'll trash it.)
    Now, with this setup:
    1) your OSX HFS+ system partition has an MBR entry, so you'll be able to see and read it under Windows with the BootCamp 3.0 HFS+ file-system drivers.
    2) your HdaSys storage partition has an MBR entry, so you'll be able to see and read it under Windows
    3) your WINSYS volume with be the last partition which Bootcamp demands (or else you get the hall.sys error.)
    Then, you can install Windows into WINSYS, reformating to NTFS during install.
    Then, since Linux is GPT aware, you can install it into LinSys which doesn't have an MBR entry and is only GPT. (Depending upon your RAM, you might also want to have a SWAP partition after LinSys.) However, since Linux does require a BIOS/MBR boot in order to get full video support, during your Linux install, you need to install GRUB to the start of the HdaSys STORAGE partition -- then GRUB will boot off a BIOS/MBR partition, gaining video support, but can still point to the rest of the Linux install on the GPT partition.
    Now, since the Mac startup selector will only give you a choice between OSX GPT volumes and 1 BIOS/MBR choice, you'll need to either setup Windows or GRUB to be your secondary OS chooser (between Windows and Linux), or use rEFIt to be the single startup chooser between OSX, Windows, and Linux instead.

  • Shrink HFS partition and extend NTFS partition with Disk Utility?

    My 10.7 iMac has two partitions: HFS+ & NTFS. The NTFS was set too small and is nearly full and I want to shrink the echoingly under-used HFS and add the resulting excess to the NTFS one.  Is this practicable?  I can see via Disk Utility that the Mac partition can be shrunk but no way is shown for modifying the NTFS side.  Maybe using a Linux tool is advised?

    You can't. If you try either Windows or OS X or both will no longer boot. You can try a aftermarket disk partitioning program but most that work on HFS partition don't work for Windows and those that work for Windows don't work on Mac extended partitions.
    The only real option is to backup the Windows partition with something like Win Clone then use Boot Camp assistant to remove Windows and the partition then again to recreate the Win partition in a larger size. After that install windows and then use the Win Clone software to restore Windows.

    For the first time that I know of a file appeared after I partitioned a new external hard drive.
    The file is listed in Disk Utility under the grey line

    It says it is located on the boot drive at:
    /private/var/folders/dZ/(long string of alpha numeric)
    (Note: Tried to post a screen shot here but I failed that task.)
    The file must be an invisible file or my bifocals are cloudy because I did not find same.
