Can't format HHD drive with admin User

MacBook Pro 13-inch, Mid 2010
Processor 2.4 Ghz Intel Core 2 Duo
Memory 8 GB 1067 Mhz DDR3
250 GB Storage
I'm login on admin user, but can't format my HHD to clean install., I have an installer USB with OS X Mountain Lion, when restart (even in root user) in the disk utility, can't erase or make a new partition to format the hard drive.
In the pict you can see the system can't let me even change login in admin user.
Thanks in advance.

Disable FileVault, make your changes, and reenable it.

    My cd/dvd drive quit working and is not found in device manager so I purchased an external cd/dvd rw.  Now I am having other issues with installing software and windows updates so I would like to format hard drive.  Can this be done with external cd drive, if so how do I boot from it?  presario v6000 laptop windows vista 32bit os.

    Restart the notebook >> start tapping F10 key >> go to configuration menu >> Boot Order >> select the Ext DVD drive as 1st boot device >> save and exit >> Insert the recovery disc >> restart the PC >> press any key when prompted >> follow the instructions..

  • Formatting Hard Drive with NTFS instead of FAT32 on E1550

    Is there a way to format the storage hard drive plugged into the USB port using the NTFS format.
    When  using FAT32 the backup software chunks backup files into 4GB blocks.  I am told to avoid that I need format the drive with NTFS format to avoid this.
    However, the Cisco Connect does not offer a choice on how to format the hard drive. 
    It was originally formatted with NTFS, but then I had permission problems and it would not allow me to add the "admin" administrator. 
    Is there a way I can format the drive using NTFS and still keep the correct permissions configured?
    Thank you,
    Solved!
    Go to Solution.

    I have seen those instructions and I am not getting the same information on the screen they say I should.
    I plugged the storage drive into my computer and reformatted it to the NTFS format.  I even created a folder under the root called "Backup." 
    But when I plug that drive back into the E1550 and go to the "Disk" tab it shows:
    Detecting...
    Partition
    File System
    Capacity
    Free Space
    Create Share
    Total
    232.885 GB
    232.885 GB
    It sees something there but it is not recognizing it and as such I do not have permissions to create shared storage.
    If I select the FORMAT option at the bottom of the page, then it reformats it to FAT32 and is accessable, but it is not the correct format I need for the backup program.  I need NTFS.

  • 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.

  • How can I format an HD with System 10.4 and install Leopard Snow?

    How can I format an HD with System 10.4 and install Leopard Snow?

    You need to partion the hard drive using Disk Utility. On one partition install 10.4. On the other 10.6. As a note I trust you are doing this on a MBP and not a PPC Mac because 10.6 won't install.

  • Unable to access Runtime Services with admin user

    Hi all,
    Trying to access runtime services with admin user returns a "Authentication Denied
    The username or password has been refused by Runtime Services. Please try again."
    Credentials are correct. It seems to be some kind of lockout. I´ve copied this admin user entry in ldap and named it admin2, this "new" user can perfectly log.
    As it could be a lockout I have unlocked the user although the proper tab said there was no locked user.
    The realm is in a openldap.
    Any hint would really be appreciated.

  • U410 ultrabook: Can I defrag hard drive with SSD cache?

    Hi,
    I would like to know if I can defrag my hard drive with 24G SSD cache. I heard that it would be bad to defrag the SSD part so I would like to defrag the regular hard drive portion only (1TB). I right clicked the drive but I see four drives and can't tell which one I should defrag. It looks like the first c drive is the one, but I am not sure. Any comments would be helpful. Thanks.

    You are right that by default, drives are set to be defragged automatically. But you can also do it manually and when the date of the task is not yet due.
    Re ssd, are there permanent files in that drive? By permanent, I mean data, programs, etc.. Not the temporary files used by runned programs and the system using the caching process.

  • Can i format the drive to ntfs - cant save large files

    i bought the TimeCapsole Extreeme AC but i cant save large files - can i format the drives to NTFS??
    is there any other soultion to this?
    Tx

    The thing is that in windows its a map drive that i can see the files but cant save large files(more then 4GB)
    Ok.. I am rather shocked but of course the problem is entirely windows.. The drive is formatted HFS+ and a 3TB drive has no file size limitation other than the drive size.
    Windows for some stupid reason when it maps drives has decided it must be FAT32 and applied that.
    Get rid of the drive mapping.. !!
    Try accessing it via network.. ie
    \\TCIPaddress and see if you can get around the 4GB file size barrier. If not I will take another look at the problem.. although I have to say windows is windows..
    It should see the TC as a NT Server and have no file size limitation at all.

  • Can i use external drive with pc and mac??? files be recognised by both??

    hi
    i have two external hard drives, with stuff from my pc on them.
    can i plug them into my macbook? and just copy files?
    usb hard drives.
    one i think is one or the other, mac or pc, not both at same time, unless i partition and format i think. maybe the other one too.
    i have a 8gb file on my pc, im trying to get into my macbook.
    how can i???
    i have a 160gb ipod, its only 30gb full, and pc says not enough space on it.
    why is this???? the file is only 8gb......and theres over 100gb free on my ipod.
    anyone help?
    cheers

    If your iPod is formatted FAT32 there is a 4 GB file size limit. Obviously an 8 GB file exceeds the limit.
    In order to use any drive on both a Mac and a PC with full read/write capability the drive must be formatted MS-DOS (FAT16 or FAT32.) A drive formatted NTFS is read-only on a Mac unless you use third-party software such as MacFuse with NTFS-3G or Paragon NTFS.

  • Can't format external drive for Mac

    I got an external Seagate Freeagent 750GB drive to use with my new Mini. It came formatted as a windows FAT volume. Since I don't have a FW400 to FW 800 cable yet, I have it connected via USB. When I try to reformat as a Mac drive (with any of the 4 case-sensitive / journaled options), I get an error, but I can then reformat as FAT. Does anyone know how I can format this drive as mac and what the problem is?

    It may have something to do with the partition scheme. There are at least three different schemes. One is used for windows formats (so you can use FAT32 or NTFS format), one is used for Intel Mac (probably GUID, not sure), and one is used for PowerPC Mac (probably the Apple Partition Map, again not sure). I don't know whether it is smart enough to choose the appropriate scheme for you when you have selected a format for your partition. Try to select the right scheme for Intel Mac first, and then decide on the format on each (if you have more than one partition on that disk) partitions.
    I think you have to make sure the format is compatible with the scheme, especially when you have multiple partitions on one disk. You can't format one partition to FAT32 and another to HFS+, although it will try to do something, but it will end up with error.
