Setting up sparse disk image on external drive

I am trying to set up an sparse disk image on an external drive and I am not getting the standard screen that I have seen referenced. My only options to select are image format and encryption, not image size, etc. I have the external drive formatted as Mas OS extended. Any suggestions are appreciated.

Open Disk Utility > File > New >Blank Disk Image...
or use the "Option-⌘-N" Key combo (with Disk Utlity open).

  • Moving Sparse Disk Image onto Hard Drive

    I created an 8 gig sparse disk image of a 15 minute video.  I want to move the sparse disk image off my computer into an external hard drive.  I cannot seem to be able to do this.  The sparse disk image shows up as a hard drive and I cannot drag and drop it onto a folder I created for sparse disk images on my external hard drive.  My goal is to store it there and be able to double click it to bring it back into Final Cut Pro X as a Drive containing my video.

    Unmount the sparse image. Once it's mounted it's a disk. Unmount it and you can move the file that is the sparse image. Once you've moved it you can reopen it and mount the disk again.

  • Cannot remove Disk Icons from Disk Images or External Drives from Desktop

    After years with PPCs, I just upgraded to an Intel Mac. I am now running into a funny problem. The majority of the time (although occasionally it works as it should), I am unable to eject disks. These include disk images from my internal hard drive, external hard drives, and disk images from external hard drives.
    I do not get the “Cannot eject this disk because it is in use” error that happens when something is trying to access a file on the disk; instead, nothing happens. I’ve tried ejecting by dragging the icon to the dock, hitting the eject icon in finder, right-clicking and ejecting from there, and even using a terminal-based script that I found on the WEB. None of these do anything- no errors, but the icon hangs about as if nothing happened.
    Occasionally I cannot log off at all (I just get the SBBOD); here I have to do a hard reboot. Sometimes I can log off properly. Either way, all seems to be fine when I log back in.
    I’ve run Applejack multiple times.
    Any suggestions would be most appreciated! Thank you.

  • Encrypted disk image on external drive prevents that drive from ejecting

    I've tested this a few different ways, and it seems to be a rather consistent problem.
    I have an external USB hard drive (seagate) and on that drive I use encrypted disk images to store my data.
    (because it's a portable drive, I'm nervous I'll lose it and then someone will have access to my stuff).
    So anyway, whenever I mount the sparse bundle disk image, when it comes time to eject the drive (after ejecting the disk image of course), it hangs for a while and then the Finder says it can't eject, but that I can Force Eject the drive.  When I chose to Force Eject, it works, but I don't like having to force it every time.
    Anyone know what's up?
    Thanks,
    Brian.,

  • Trying to create HD disk image on external drive

    I'm trying to use the disc utility to create a disk image of my HD, saved to an external drive (500 GB, My Book) via FireWire. After choosing the appropriate origin and destination info on the drop-down menus, and clicking Save, I get a dialogue box that for an instant shows the operation in progress, then reverts to: Unable to save DMG, resources busy. I might not have the exact words, but it's very close.
    What am I doing wrong? What resource is "busy", the HD or the external? The dialogue box doesn't indicate that info. I'm not aware of any obvious conflicts. No other applications are running.

    Were you trying to copy the Mac OS volume?
    I think the OS itself is a big program that is running. So somehow the source is changing every minuets. You may try SuperDuper! or Carbon copy cloner to do what you want, both of which are free, at least some of the main functions are. They should have no problem when dealing with the OS that is currently running.

  • Disk Images and External Drives - PLEASE HELP

    Hi all,
    I've got to a point where i can't afford to keep buying expensive drives to work form with Final Cut Pro X so decided to just work from several high spec drives and then back them up on other cheaper drives, reformat the high spec ones and start again.
    Not really understanding how disk imaging works I hoped I could carbon copy mountable and read and writeable drives (in this case a thunderbolt lace SSD)  on to a cheaper mass storage, wipe it and start again. I hoped it would then appear on the drives top level just as the drive appears on my desktop, and that I could access it if needed or port it back to a single drive at a later date? Is this possible? Can anyone help? So far everything I've tried has failed.
    One thought I did have was to create several partitions on the cheaper mass drive and duplicate it on to there? But I can't find any help or instruction for this online and need to make sure its write before I go deleting old projects.
    Attached are a picture of what I have (the disk image file) and what I was hoping to create (a mountable replica of a working drive on an external HD)
    Any help greatly appreciated.
    Robin

    You can research the terms disk image and back up for several hours. That might not help.
    None of the back up routines I am aware for for video and large media files use any compression or bundling systems like .dmg. I think your best bet is to make one-to-one copies of your files to your cheap drives. If you need the older projects, you copy them back to your working drives. That's pretty much how it's always been unless you are have a nice NAS RAID with mirroring to another rack of drives.
    The problem with cheap mass storage is no that it's unreliable. It's just not QUITE as reliable as more expensive systems. Having a copy of your work on a disk that might or is likely to fail is almost the same as not having a backup at all. but there is a point of diminishing returns for all of us in this business. This trend toward 4k and 8k, and FCPX's inability to manage media efficiently, means we all must add TB of storage for every project. A friend of mine includes a couple of TB drives in his fees. The client pays for and gets the drives.

  • Disk Utility Error 61 when attempting to create disk image on external driv

    I would like to make occasional archive backups of my three macintosh computers. I bought a new Western Digital 2TB drive for this purpose, and formatted it as Mac OS Extended. Trying to do a disk image backup using Disk Utility, I follow the directions:
    - Startup from an install DVD.
    - Start Disk Utilities and select "Restore"
    - Drag "Macintosh HD" into the Source box
    - Click on "New Image" and select compressed and 128-bit AES encryption
    This leads to the error message: Unable to create "....." (error -61)
    I have enocountered this problem both with my iMac G5 and a MacBook, both running Leopard.
    Does anyone know what this error means, what I am doing wrong, and/or if there is another way to create disk image backups? Help!

    1. For reasons I don't know disc images seem to become more fragile the larger they get. They also can be subject to file corruption that affects the entire disc image, whereas file corruption on a clone would only affect certain files.
    2. You cannot put multiple clones on the same volume. Each clone must be on a separate volume, but you can have multiple volumes on a single drive simply by partitioning the drive accordingly. Of course you need a drive large enough to accommodate each clone. Each clone should be to a space equal to the capacity of the cloned drive.
    3. I'm not a big fan of TM, although I must confess it has become more reliable since it's release, especially with Snow Leopard. However, there are many backup utilities that can create clones, perform incremental updates, and archive changed files. See the following:

  • Sparse Bundle Images on external NTFS formatted drive

    I'm currently in the process of re-arranging my own backup setup following on from my recent update to Snow Leopard. For this purpose i have the lend of a NTFS formatted external drive and used a large Sparse bundle disk image.
    Under 10.5.7 with the latest MacFuse and and unknown version of NTFS-3G i had no problem using the sparse bundle images, they mounted, I could read and write, and the images where only unmounted when I explicitly ejected them.
    Under 10.6 with the latest MacFuse and the latest NTFS-3G i have a very strange behavior.
    Read and write works fine on the NTFS drive, as do regular disk images and old style sparse disk images.
    However sparse bundle disk images will mount and then immediately dismount again. I have no problems mounting the sparse bundle images from HFS+ drives or when using the NTFS drive read only using apples drivers instead of MacFuser+NTFS3G.
    The disk image dose not see the be the source of the problem; as any sparse bundle that opens fine on a HFS+ drive exhibits the behavior when moved onto the NTFS drive. Moving the image back onto a HFS+ drive allows the image to be mounted.
    The problem is that I require to move some additional files onto the NTFS drive so I can reformat my backup drive
    As a side note mounting using "hdiutil attach -readonly" seems to partially resolve the issue; the image will mount and stays mounted but it is read only.

    I too am having this issue. Intel / 10.5.8 attached to an SMB share from Ubuntu Linux.
    I ran a test of various image types, and while Sparse Image works, Sparse Bundle fails. Here are my logs. Happy to do some testing and log posting if anyone has a test theory to try.

  • Restore from disk image on external hard drive

    I have a early 2011 macbook pro and the internal hard drive failed. I installed OS X mavericks on an external hard drive (1) and I boot from the external drive (1). On a different external hard drive (2), I have a disk image of my macintosh HD (the computer's original hard drive with all my data on it) How do I go about restoring from the disk image on the external drive(2) to external hard drive (1)?
    I want to be able to boot from the external hard drive (1) and have all my data that I backed up as a disk image on external hard drive (2)

    I put the disk image in the source field and "backup" , the external drive I want it on, in the destination field
    When I try to use disk utility it says it must scan the disk image first, then says "Unable to scan "Backup" (resource busy)"
    "Backup" is the name of the external HD  I am booting off of, which makes sense that it says resource busy. So how is this done?

  • Deleting Sparse Disk Image Bundle from Time Capsule

    Howdy. Thanks in advance for help on this issue to anyone kind enough to spend time answering it.
    I've got a 1TB Time Capsule which I use primarily for external file storage - it's currently got just about 120GB of files on it which I have manually copied there. I only sporadically use Time Machine to do automated backups, but since I've had the Time Capsule for a good long while, there have been many backups, and relatively little space left on it. As I am not interested in files that are 8 months old, I have gone into Time Machine and deleted all the old backups I don't want, then done a fresh backup so there's a current copy of everything on my laptop. It's my understanding that deleting backups from within Time Machine clears space off the Time Capsule, and when I did those deletions, saw that the available space on my Time Capsule did in fact increase, but not nearly as much as I would have expected.
    Now, there's a file sitting on my Time Capsule called a "Sparse Disk Image Bundle.dmg", which has a filesize of 564GB - so there's where all the "free" space on my Time Capsule is accounted for.
    My question is, if I know that I don't want the contents of all the old backups, but I DO want a copy of the files I have manually copied onto my Time Capsule, is it safe to delete the 564GB .dmg file? I use my Time Capsule more than anything else as the repository for my iTunes library, and it'd be a huge bummer if I wiped out my entire music collection by deleting that file.
    So far as I can tell, the contents of my Time Capsule and that .dmg file are separate, but I don't know enough to know whether that's really the case.
    Any advice is well appreciated!

    Hi, and welcome to the forums.
    Yes, network backups are in an odd container called a +sparse bundle.+ It should be named with your Computer name plus a string of 12 numbers and letters (the hardware address of your Mac).
    Do you see your "other" files separate from it? They shouldn't be inside it, unless you specifically copied them into it.
    As long as they're shown separately, yes, you can safely delete the sparse bundle. That will delete all your backups, though, and take quite a while. If it seems to be taking forever, see the blue box in #12 of [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum).
    There is an alternative, however. You can limit the +maximum size+ of the sparse bundle, per #A8 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of this forum). As noted there, however, if you update to Snow Leopard, 10.6.3 or later, it will be automatically re-sized to the size of the TC's internal HD.
    If it's already too large, you may need to delete some more backups and/or "compact" it first. See the pink box in #12 of the FAQ.

  • HT201250 back up sparse disk image

    I have configured Time Machine to back up an external disk, which includes a sparse disk image. When I launch that sparse disk image, It becomes a secondary disk. I notice, though, that TM only backs up the outer disk and the image, and not, I think, the specific contents of the secondary disk that loads from the image. When it backs up the image, is it also backing up the data stored on the secondary disk that loads from the sparse image? If I want to retrieve a backup from TM, would I launch the TM version of the sparse disk image and then launch that image? If so, would it include backed-up files from the secondary disk? I can't seem to find a way to include the secondary disk on TM's back-up agenda. Thank you.

  • Sparse disk image

    I am trying to make free space on my HD but I got this Sparse Disk Image that has 203 GB and I don't know how to deal with this, whatever it has on it I don't need it, everything is bucked up on my external HD?

    I sent it to trash and and when trying to empty it securely it gets stark...
    I had may be 16 GB free on my HD and when I started do erase the  free space on it , it gradualy lost all that space while being emptied and sudenly in  my trash apeared this Sparse Disk Image of 203GB, which I don't remember creating it, before I did not even knew  what is this until I got this problem.

  • Sparse Disk Image will not open along with encrypted document

    I have two problems. I created a sparse disk image of my documents folder and encrypted it but recently when I select it and double click it to open it up nothing happens. I put in my password and in the finder window it shows the image but no documents folder will open up.
    I ran disk utility and disk warrior and all is okay on my hard drive. I did burn a CD of the files in this folder so I do have a backup but wondered why it will not open up now, any suggestions?
    The second problem is in this same folder, I created a word document years ago when I had my old G3 iMac and used at times MS Word 2000. At the time, I locked this Word document, and now it is encrypted and it won't open up. I can't remember the password used back in 2000 and so this document is encrypted and I don't know how to decrypt it, any suggestions.
    I do know there are software programs to delete passwords in MS Word and that they will decrypt my document, but the ones I try to download won't work. Any suggestions.
    Thanks,
    DaisyMay

    A follow up to my MS word document. I found that I created the file in MS word 2000, and I used the Apple File Security for OS 9 to encrypt it. I can't remember the password, and I do not find anything in the key chain listing.
    I have Pages 08, but I don't think I can use it if I can't remember the password to unlock this old document. Is there a program to decrypt this without a password?

  • How Do I Create a Sparse Disk Image?

    I'm having trouble creating a sparse disk image. The instructions I'm following are:
    +1. Open Applications->Utilities->Disk Utility.+
    +2. Select File->New...->Blank Disk Image.+
    +3. Name it, set the size to what you'll need, set the encryption to AES-128, and set the format to sparse disk image.+

    +read only+
    compressed
    read/write
    +DVD/CD master+
    Is there something I'm missing?

    Nevermind, found it.
    Figured out there's a difference between pushing the New Image button in the toolbar vs. going to File > New > Blank Disk Image...

  • Encrypted, sparse disk image stored on WebDAV server: problems mounting

    My goal is to have secure, encrypted storage to back up my computer to a remote site. The remote site is an internet hosting provider who provides a lot of disk space and bandwidth, and also serves up WebDAV, for a very small price.
    I have created a 100GB sparse disk image, with encryption, and stored it on the remote server. I then mount the directory containing the sparseimage (which is itself password protected using .htaccess) using WebDAV. My plan is now to mount the disk image, and use rsync to copy changes on my computer to the disk image.
    This worked perfectly when I tested with a small sparseimage. It was interesting how the OS seems to buffer the changes in chunks: rsync appears to be copying a lot of files super fast, then it stalls as network bandwith suddenly throttles up for a while, and they take turns this way.
    Unfortunately, after copying a few hundred MBs into the image, I am now having trouble.
    First, when I try to mount the disk image, I see an enormous amount of data start transferring over the network. It literally saturates my broadband connection for at least an hour (I haven't been able to go longer yet). It seems to first download at top speed for a while, then switches to uploading at top speed for awhile. During this time, I notice that a mount_webdav process is consuming large perentages of CPU. However I can't see anything else going on at this point -- the disk image isn't mounted yet, all this thrashing seems to be from the process of the image trying to mount.
    So first question: is this normal? Does anyonw know what actually happens when you issue "hdiutil attach" on encrypted sparse images? Does it have to touch and read through everything in the image once or twice? Maybe this is just a Bad Idea™
    Second: the webdav server always ends up getting disconnected during this process before the image actually gets mounted. Do you think I'm trying to do something that tests, and exceeds, the limits of WebDAV?
    Thanks a million for any help!
