  • No Erase option in Disk Utility for an SSD Drive!

    Hi guys,
    Made a time machine copy on a 500gb external hard drive of my 13" MBP with a HDD currently in it.
    Then took my 500gb SSD from an old 15" MBP, removed the HDD and put it in my 13" MBP.
    Opened up 13" MBP in restore mode. Chose restore from time machine back up.
    Choose the time machine external drive as source. Then chose the SSD drive to restore to.
    Said it was erasing the drive... Asked for a password...
    I typed in my usual password. It then said the SSD drive couldn't be erased.
    Took the SSD out and put the original HDD back in.
    Plugged the SSD into a firewire 800 caddy to try erase it in disk utility as an external.
    This drive will show up in disk utility but the erase option isn't available.
    I can repair the disk but it says the disk is perfectly fine.
    I can click on the partition option but everything is greyed out and I can't partition it at all.
    This drive will now no longer show up on the desktop or finder.
    This is driving me crazy!
    Just want to erase the SSD, use time machine to restore onto it and get busy.
    Please help!
    Thanks,
    Chris

    Aha! I only looked at 'format' list, didn't notice the 'option' list.
    problem solved.
    thank you !

  • Erase functions on Disk Utility in Lion

    Having installed Lion on my MacBook Air I find the erase functions on Disk Utility are no longer available. Any ideas?

    Thank you for the link Michael.
    I'm still wondering why I can't erase or partition my disk.
    It works fine in SL on my MacBook Pro Unibody (late 2008). It even works on my old white MacBook from 2005 which I upgraded to the OS X Lion.

  • Erasing Securely in Disk Utility

    Erasing Securely in Disk Utility
    I wish I could send this directly to the Apple software engineer in charge of Disk Utility, but maybe there is someone on this Forum who is technically very savvy and would stake their reputation on their answer.
    I would bet thousands have had this same question cross their mind...
    I'm trying to understand the process regarding erasing a hard disk using Disk Utility.
    For this example, use a 300 GB hard drive that has the following:
    150 GB of readable files
    100 GB of files that were sent to the trash and emptied (but not "secure empty trash"… so just their directory info was erased when trashed)
    50 GB of never used free space
    I'm confused by the wording in the Disk Utility's erase options.
    One of the choices is Zero Out Free Space.
    Does that mean it only writes zeroes over the 50GB of never used space?
    Or does it write zeroes over the 50GB AND the 100GB spaces?
    Another confusing choice is Zero Out Data
    Does that mean it only writes zeroes over the 150GB of readable data?
    Or does it write zeroes over the 150GB AND the 100GB of unreadable data ?
    If the latter is true, then the sequence probably should be
    erase free space (unless it ONLY writes zeroes to never used space)
    then choose
    zero out data (assuming it also zeroes the unreadable data too)
    Thanks for any help

    Perhps I did not make myself clear (or you misread a verb or two).
    I did read your link,but it does not clarify the technical design of this software.
    The Erase button lets you "Zero Out All Data", but data to me is a file (whether or not it is readable in the directory of not).  Whereas Free Space can be either virgin territory or trashed files with the directory info stripped clean.  So why do you say that Zero Out All Data would include virgin disk space when there was never data there ?
    Also if Erase>Zero Out All Data "writes zeroes to every byte on the drive", and projects an erase time of 13 hours, then why does it estimate 2 days 9 hours when I choose Erase Free Space>Zero Out Deleted Files? (Which further confuses the reader with this Apple description: It writes zeroes over the UNUSED space in the disk.) (My capitalization for emphasis).  Yes, parts of it are CURRENTLY not being recognized, but it IS filled with data (as opposed to the virgin space being filled with no data).
    So you can see why I am confused.
    And though you may be right, I alwatys ask. "Would you bet your child's or your mother's life on your answer?"
    That's why I left it an Open question for the moment ... hoping to also snag an Apple Moderator.
    Thank you for your help though.

  • Brand new Mac, had to erase drive through disk utility as time machine back up failed. Now disk utility only has the option to install Mountain Lion which my Mac won't allow. Anyone any ideas as my Mac won't load anything up but disc utility!

    Brand new Mac, had to erase drive through disk utility as time machine back up failed on initial setup, USB cable popped out Now can only access disk utility as won't load to log in screen. The only has the option in disc utility is to re-install Mountain Lion which my Mac won't allow or loading another time machine back up but after an hour of it processing, that didn't resolve the issue either! The time machine back up is the latest back up of my Mac Book Pro which was using OS X Maverix. I'm guessing I'm going to have to take my Mac to the store but that would be a hassle so does anyone have any ideas?

    Follow this guide using another Mac.
    Insert your newly created Mavericks USB into you Mac, press the power button and then hold down 'option,' until it gives you an option to boot from the USB. You will then be able to erase the internal disk with Disk Utility and reinstall Mavericks straight after.
    After that you should be able to use Migration Assistant to restore your applications and user data.

  • How do i run the disk utility to repair permissions:confused;

    how do i run the disk utility to repair permissions
    i think i hav the same problem as you all iv been
    restarting and deleting and renstaling but nothing seems to work
    the only thing i havent don is this repair prmission
    thing can someone type some instuctions on how or lead me where to
    go

    are you using mac OS10.2 or later?
    if so, this is what I did to solve this most frustrating
    problem. Go to Applications/Utilities/Disk Utilities
    In the Disk Utility window, click on your hard drive, make
    sure you're in the First Aid tab, then click on Repair Disk
    Permissions.
    Once the permissions were repaired, I took the advice of
    another user here on the forum and reinstalled Flash Player 6, as
    it was the one that was working before I tried to upgrade and it
    screwed everything up.
    Hope this helps

  • Erase HD in disk utility is grey, not mounted, locked. help!

    i have a 2011 mac mini running Mt. Lion. it's running really slowly and i want to wipe the HD and restore it back to orginal factory settings. like the day i brought it home. i boot in to the disk utility using command-R on start up, select disk utility but my mac HD is grey, erase is grey. i can verify it and repair, but cant erase it. when i click "get info" it shows it as not mounted and locked. where do i go from here to restore my mini!
    thanks!.

    i thought if you booted in recovery mode then you were booted from the partitioned part of your HD, and thus can errase all your data on the HD.
    how else does someone restore to factory settings then?

  • Erasing Volumes using Disk Utility

    I used Disk Utility to make copies of numerous cds and dvds. Doing this created a long list of volumes on my harddrive that I can not delete using erase or erase empty space (these fields are grayed out). I tried booting from the OSX disc however when I did that the volumes weren't even visibile. I also tried converting the disk images to a writeable format. All this did was make a copy of the existing volume. Does anyone know how to delete Volumes in another way, either using disk utiltiy or other software?
    Thanks,
    Dean
    Macbook   Mac OS X (10.4.7)   disk utility, delete or erase volumes

    If you are getting nothing for file system what has gone wrong is something in your computer/operating system, not on the iPod.
    Try running Scandisk first, then formatting or, at this is not recommended generally, if that doesn't work partition the iPod and then format it.
    But you might also want to consider a reload of XP. I reiterate, if it gave you nothing to select under file system this is most likely a problem with your operating system or USB chain.

  • How to erase DVD-Ram disk

    I have a half dozen DVD-Ram disks (from my now-dead DVR). They mount on the Desktop and I can see the contents (VRO and associated files). I am exploring the various Toast, Streamclip (etc.) options to play/rescue the files. Once that is done, how can I erase (and rewrite/reuse) the disks? Neither Toast 8 nor Disk Utility seem happy with formatting/erasing this media. Any ideas?
    ~ Keri

    Ah,... makes sense. Thanks! And here's what it says [below].
    So, it seems to say I cannot "erase" ... but I can "overwrite" (??), which is splitting a hair finer would have occurred to me.
    Okay. Then, how would I "overwrite" the files -- what application could I use to do this? Toast? Other??

  • Partitioning, Disk Utility, Time Machine

    I attempted to use Boot Camp Assistant to allow me to install Windows. During the partitioning process, I got a message that instructed me to restart my computer... during the partitioning process! So I did, because I didn't think my Mac would instruct me to do something that would hurt it. Well, it did. All of a sudden I'm still not using Boot Camp, but my HD is severely shrunken! Is there a way I can "undo" what I possibly did?
    Further, I tried to verify my HD and that failed as well. Following is the sequence of messages that DU gave me:
    +Invalid volume free block count+
    +(It should be 9957181 instead of 4558289)+
    +The volume Macintosh HD needs to be repaired.+
    +Error: Filesystem verify or repair failed.+
    I use Time Machine to periodically back up my HD, and actually just did. If I restore my HD, how do I use TM to get my computer back to just how it was?

  • Erase button on Disk Utility doesn't work

    II'm trying to erase my external HDD so I can use it to restore a backup of my HDD , since there's a problem with my HDD  and my MacBook Pro is stuck on startup, but the erase button (is not grey, it looks functional) doesn't respond. I press it and nothing happens. What can I do? I need to backup my files ASAP

    Connect the external drive to another mac ( a friend maybe?) and re-format it using that.
    I'm not 100% clear on what you're trying to achieve here, but it sounds like your MacBook HDD is corrupted. Make sure you've tried repairing the HDD using disk utility in the recovery partition. This will tell you if the disk is usable. It may repair it and return your system to normal operation.
    If your HDD is corrupted or damaged you may have trouble backing it up to the external drive anyway.
    Personally I would remove the HDD, replace it with a new one and re-install OS X onto it. While you're out getting a new HDD, pick up a SATA to USB drive caddy that will allow you to connect the old HDD to your new restored Mac via USB. If it's readable then you should be able to copy data off it.
    Your ability to re-install to a new hard drive will tell you if the problem was with the old HDD or with the Macbook itself.
    If the old HDD is not readable you may have lost your data, or you may need to go to a professional data recovery service. This is why backups are essential. I would recommend using your external drive for backups with Time Machine.

  • Erasing a partitioned disk

    I have been given an ibook G3 with 10.2.8 installed and OS9 on a partitioned disk. I want to erase the entire disk and get rid of the os9 partition and reinstall the 10.2 software. Could someone point me in the right direction. I have no idea how to do this. Thanks!

    Hi bliss!
    Why not take this opportunity to upgrade the iBook to a newer version of OS X?
    Tiger is available for purchase at The Apple Store (U.S.).
    Panther, is no longer available directly from the Apple Online Store, as Tiger 10.4.x is the most up to date OS.
    If you know what to look for, a Full Retail Version, of the Panther Install CDs, or a Full Retail Version, of the Tiger Install DVD, can also be purchased rather inexpensively, at some online Apple retailers, Amazon, Panther On eBay, FastMac, etc.
    Be sure not to purchase grey, upgrade or machine specific CDs or DVDs.
    Panther is only on CDs, not DVDs.
    The discs should look exactly like the images in the above links, and not say Upgrade, CPU Drop-in DVD, or "This software is part of a hardware bundle purchase - not to be sold seperately." on them.
    Additional info in these links.

    What's A Computer Specific Mac OS X Release
    Software Update, Upgrade: What's The Difference?
    Once Panther 10.3.x is installed, you can use 10.3.9 Combo Update, to upgrade to the final version.
    If your Mac meets the Tiger System Requirements, you could also consider installing that, and then use the PPC 10.4.10 Combo Update, to upgrade to the current version.
    Panther System Requirements
    Additional Panther System Requirements
    Additionally, Tiger ships on a DVD, so if your Mac doesn’t have a built-in DVD-ROM player, you will have to use an alternative method.

  • How to restore Windows in disk utility?

    So I am trying to transfer a windows image by target booting to a Mac Pro, but the windows side wont, it's giving me a no bootable device error, Help!!!.

    You have not really detailed your setup and how you used WinClone, whether you have a divided disk drive or not.
    Thread with suggestions on Windows backup methods:
    https://discussions.apple.com/thread/3798090
    Paragon CampTune
    Paragon CampTune is a commercial product that is designed expressly for this task. http://www.paragon-software.com/home/camptune/ It consists of a downloadable ISO that needs to be burned to a disc and booted from in order to resize the partitions costs US$19.95.  
    Securing Dual-System Configuration
    Imaging is still the most affordable and robust way to secure computer data. Unfortunately Mac OS X backs up only HFS+ volumes, leaving Windows with dual-system configurations unsecured. You can permanently lose all of your data unless you have a Windows-compatible backup solution.
    Paragon’s CampTune and Paragon’s Drive Copy for Mac can secure the entire dual-system configuration. CampTune creates traditional images of volumes or entire hard disks, Drive Copy can copy them to other disks. In case of an emergency, you can restore the previously created image or copy all your data back to its original state.
    GParted Live
    GParted Live is similar to CampTune as it is also distributed as a bootable image that needs to be copied to a CD/DVD or USB flash drive. As free and open source software, distributed under the GPL, it will always be available free. Since it has more functions than CampTune, it may be harder for folks who are not as experienced with partitioning hard drives. http://gparted.sourceforge.net/
    iPartition
    Coriolis Systems' iPartition is a £29.95 ($44.95 US) utility that runs in Mac OS X and allows resizing of all of the relevant partition formats, including HFS+, FAT32, and NTFS. It provides a Mac-oriented user interface that may be easier to manage than some of the free utilities. As it is not capable of resizing the boot disk, it requires a bootable external disk or a boot DVD. (A tool to create a boot DVD is included.)
    Paragon Partition Manager
    From the makes of CampTune is a commercial tool that is similar in functionality to GParted Live, but has a more polished/friendly user interface than GParted Live. Previously only the US$79.95 Professional version supported all the features required for this, but as of version 11 the US$39.95 Personal version has also been reported to work. http://www.paragon-software.com/home/pm-personal/
    Winclone/Disk Utility
    Winclone is a free tool for creating and restoring backup images of your Windows partition. One of its key features is that it can restore to a larger partition than the one the image was created from.
    NOTE: Winclone has been discontinued, but for now remains available and capable of completing these tasks (including creating and restoring Windows 7 images).
    Winclone updated to support Lion Winclone updates and download
    Disk Utility can resize HFS+ (Mac OS) partitions, but is currently incapable of resizing NTFS partitions, so you could use it to reduce the size of the HFS+ partition and create a new larger placeholder MS-DOS (FAT) partition
    The full process would be:
    Backup Windows partition with Winclone.
    (if the new Windows partition is smaller than the old one make sure you set the preferences in Winclone to save the image as an uncompressed dmg)
    Delete old Windows partition
    Resize current Mac Partition
    Create new Windows partition as MS-DOS (FAT) in free space after Mac OS partition.
    (If the new Windows partition is smaller than the old one an additional step is required: shrink the filesystem on the image by selecting Tools->Shrink Windows (NTFS) Filesystem)
    Reboot your computer for the new Windows partition to mount properly (winclone may not restore if you don't reboot)
    Restore Winclone partition over new Windows partition
    An alternate Winclone based process is described in the External Guides section
    Native OS utilities
    MR user Kazyua reports that you can use the disk management utilities provided with the current operating systems if you want to do it manually. Windows 7 and OS X both have partition resizing functions built in. In OS X, open Disk Utility and manually shrink the mac HFS+ partition by dragging the lower right corner. Then in windows go to the start menu and type "disk management" into the search box then hit enter. You should get an overview of the drives you have and the individual partitions. Right-clicking on the partition gives an "Extend Volume" option. The Windows NTFS volume should then be extended into the free space you created with Disk Utility. This method has not worked for other users, so try at your own risk.

  • Cannot write or delete files from DVD+RW after erasing it through Disk Utility. Help.

    Hello. I erased (completely not quickly) my 4.7 GB DVD+RW with the help of Disk Utility in which it was successful, it asked me to open Finder, DVD Player or Disk Utility, I chose Finder. Then I dragged a MP4 and burned it, it asked me to name the blank DVD+RW so I named it and then it successfully burned the file onto the DVD+RW, now when I try to burn a file again (as it is a RW) by dragging the file to the DVD+RW window the cursor shows a stop sign with it (the sign which is a circle and there is a diagonal line it it) and it denies to write files again, when I try to remove a file it doesn't do it as well. Please help.
    P.S When I secondary click on the DVD+RW icon and click get info it says "Capacity : 4.7 GB" and "Available : 0 Bytes" even when the MP4 file is just 8.3 MB.
    Computer: Macbook Pro 13-Inch (Non-Retina) Highest Configuration.
    Please Help.

    Hello Aditya's Apple,
    Thanks for using Apple Support Communities.
    If you want to write again to a CD RW or DVD RW disc you will need to first erase it, and then start another burn process.  The only time you can burn multiple times to a disc without first deleting what is on it, is by multisession burning.  The following article explains more.
