Question about Disk Image Backup/Restoring

Ok, so i have a weird Boot Camp error that requires reformatting of my whole drive. Now I have thought up a procedure that I think will work, let me know if this is a viable option:
1: Hook up a 320GB External Firewire Drive
2: Boot up using the 10.6 DVD
3: Go into Disk Utility
4: Make an image of the Macintosh HD and save it to the External Drive
5: Format the Macintosh HD
6: Restore the Macintosh HD using the Image
If i do this, will everything be hunky dory? Nothing is wrong with this? Thanks!

Copy the content of the external to the internal--into an appropriately named folder. Then, clone your internal to the external. I would just use DU. First, use DU to partition the external GUID--which also will format it OS X extended (journaled). You might want to make two partitions if you have room (see below). To clone, go to the restore tab; select your internal volume and drag it to the source box. Then, select your external and drag it to the destination box. Then, click restore. If you can't perform the operation without previously selecting erase distination, then select it; let DU erase again; and then click restore.
In an hour, more or less, you'll be ready to take care of your internal drive issue. Piece of cake. When you have fixed the internal, then just clone you Sno install on the external back to the internal. If you made two partitions, then copy the original external data to the second partition and remove it from your Sno installs if you want.

Reinstalling, Migration Assistant, Disk Image backup

I am in the unfortunate position of having to reinstall Tiger on my iBook. The disk image containing my backup files turns out to be non-bootable.
After reinstalling Tiger (I have the updates up 10.4.10 on disk), will I be able to use Migration Assistant to replace the folders created by the re-installation with the same folders containing my backed-up information from my disk image backup?
If I can't use Migration Assistant, how should I best get my backed up files on to the iBook...simply replace the folders? Any suggestions to reduece the pain appreciated.
thanks, Michael

"...After reinstalling Tiger (I have the updates up 10.4.10 on disk)"
All you need is one update, the 10.4.10 combo updater for ppc.
"...will I be able to use Migration Assistant to replace the folders created by the re-installation with the same folders containing my backed-up information from my disk image backup?"
When you use Migration Assistant you are connecting to another Mac via firewire and transferring pretty much all your files, applications and settings.
:...how should I best get my backed up files on to the iBook..."
You may have to do file by file unless someone jumps in here with a better idea.

Problems with Disk Utility backup & restore via DMG disk images

I attempted to backup and restore a 2TB external raid storage device using the recommended Disk Utility procedure for 10.6.6. One of the HDDs in the raid enclosure had started to fail.
First step was to create a new image from the 2TB device. I accepted the defaults of compressed image format and no encryption. The image took about 15 hours to create, and when complete, I was left with 2 files:
OWC2TB.dmg (1.1TB)
OWC2TB.002.dmgpart (486GB).
To check the DMG I ran the Disk Utility "Verify Disk" on the DMG, and got the message "The volume OWC2TB appears to be OK". The DMG is described in DU as:
Description: Apple UDIF read-only compressed (zlib)
Connection Bus: Disk Image
Total Capacity: 2 TB
Disk Write Status: Read Only
Partition Map Scheme: No partition map
I then replaced the failing HDD in the enclosure, recreated a new 2TB filesystem on the device, and attempted to restore from the DMG image.
The first attempt was to use Disk Utility "Restore" function. I specified the DMG as the source and the new device as the destination, and chose "Erase Destination". This failed immediately with the error "Restore failure. Could not find any scan information. The source images needs to be imagescanned before it can be restored".
After researching this error I tried to correct it by selecting the DMG in Disk Utility and running Images => Scan Image for Restore. This failed immediately, complaining there was insufficient disk space. More research revealed it needed the same amount of spare space on the same disk to do an imagescan. So I had to free up an EXTRA 1.5TB of space in addition to the space the DMG consumed. Not very user friendly.
The next attempt to imagescan the DMG got further than the "insufficient space" error. It displayed "Scanning image OWC2TB.dmg, Block Checksum Partition #1". This ran for about 10 hours. At the end, it displayed a new error message "Unable to scan OWC2TB.dmg (internal error)".
Next I tried to mount the DMG and copy the files manually. My first attempt at this resulted in a "Verifying..." phase which looked like it will take about 10 hours, so I clicked "Skip". Soon after I got an error message "Unable to attach OWC2TB.dmg (no mountable file systems).". Now I am trying a mount with the Verify option...
Can anyone suggest what I can try next to restore the DMG?
I think the problem might be the fact the DMG is split in two parts, but the imagescan/restore software does not know how to read the second part? Is there a way to join these into a single DMG?

Superduper backup to disk image then restore from disk image

Im trying to get bootcamp to work but it told me to backup, format and restore. Im currently copying my data to a disk image. Am i able to restore this or is it pointless?
Thanks

You can do it your way, but the intended way is to use FileVault to encrypt your Home folder. When you log out of your account then TM will begin the backup of the encrypted Home folder. No need for you to encrypt or decrypt your own disc image.
If you allow TM to run hourly backups as you now do, then both your Home folder and your backups are not secure.

Satellite P870 - simple image backup & restore software required

Does anyone know of simple disk imaging software to back up and restore C: drive including the OS and every file.
I used to use BartPE which had the shell of Windows XP on the CD and booted from the CD and allowed an image to be made or restored. It didn't matter if the PC's OS was broken was a simple OS on the CD plus Norton Ghost 8.
My Satellite P870 can only boot from a USB (selected in the BIOS) and I've been unsuccessful getting my BartPE to boot from a USB. Similarly I installed Odin Imaging software but it doesn't boot from the USB either, though I can run it from Explorer (but relies on Windows 8 loading properly).
I also downloaded Paragon Free Data Recovery but it wants to install the program on the laptop. I want a purely portable drive/image copying program.

Firstly, I have to correct where I said the P870 does not boot from the optical drive. Both USB and ODD are options. In the process I managed to create a bootable USB with EaseUS and a bootable CD with Paragon Backup & Data Recovery 2013 (free version). However the laptop would not boot from the USB or CD despite setting USB or ODD at the number 1 position in the BIOS.
The following changes to the BIOS (version 2.30) does cause the laptop to boot from the USB or CD as the case may be, however it is not a permanent solution as the laptop will not boot into Windows even if there is no USB device attached or a CD/DVD in the ODD.
Set Secure Boot to disable. Set Advanced System Configuration Boot Mode to CSM Boot.
When the job is done Boot Mode will need to be put back to UEFI Boot. If there is a better way whereby the settings do not have to constantly be changed, Id be interested but its not important for my needs.
On using EaseUS to back up C: drive, I could not see the 2 partitions I had created from splitting C drive so I put it aside and tried Paragon Backup & Data Recovery 2013 (free version). I had to download the install the program on the laptop and from there, create a bootable CD (or USB).
That all worked smoothly as did running the program.
There is no need to keep the program on the laptop once the bootable USB/CD is created though I have not reviewed it for other useful operations.
The commands are relatively intuitive and the help answered one question I had along the way.
The only confusing thing I found was when restoring the data and being confronted with a string of drives to copy the data back to. Following the process of elimination I chose F drive in my case based on the drive size. The only odd thing was the cursor; each time I touched the track pad with a second finger, the cursor flew to the left or right.
That might be peculiar to the P870 and Windows 8 its pretty much straight out of the box with virtually no software installed by myself (yet).
As for my old BartPE, it caused the blue screen of death twice in succession so it is relegated to use only with my old XP laptop.

Disk Image backup

I was curious if I could make an exact image of my HD with all the software i have installed and use that image in the event i need to rebuild my machine. So, for example, OSX, photoshop, final cut and all directories on the HD so I could easily haver this backup. Can it be done if i use the disc utility?

To answer your question, it can be done with Disk Utility. You have to start up from your Mac OS X Installation Disk, and run Disk Utility from the Installer menu (because you can't make an image of the disk you are starting up from using this method). Note: If you have an external (or other) drive that has Mac OS X installed, you can start up from it and run Disk Utility.
Select the volume you want to image in the sidebar, then...
File menu > New > Disk Image from {name of disk}
Save the Disk Image file to another drive, such as an external drive.
To recover, run Disk Utility the same way. Go to the Restore tab. Click the Image... button to get the disk image into the Source field. Drag and drop the target volume from the sidebar to the field called Destination. Click the Restore button. I've done it a few times and it works fine.

Disk image backup freez

I like to make a disk image of the partition with the operating system on it from time to time as a backup to an external hard drive. Works fine with my Powerbook G4 but the last couple of times I've tried to use disk utility to make such a disk image for my iMac it freezes. I have to shut the computer down with the button. It might actually finish but I don't know how to tell!? I'd rather it just work like it is supposed to. I just to the operating system partition. I do read only and no encryption. I do this all the time but now it doesn't work. I always throw the trash out, do a repair permissions and a disk repair before I do this. The first time this froze I did have an actual repair of the disk. It said it fixed it. That does worry me. Any ideas? Steve (p.s. I am doing this from the boot disk that came with the computer.)

Disk image for restore won't verify

Hi - I'm preparing to send my G4 Pbook (10.4.11) for repair.
It was recommended that I make a disk image of the HD "just in case".
So I booted from the original install disc (10.3), launched Disk Util and made a new image on an external drive. Read only, not compressed. About 3 hours later I had a DI and decided to "verify" it. It would not. So I rebooted from the normal system and tried to mount the new DI. It would not and gave a message "the DMG is faulty and it may damage your hard drive if you mount it". So I trashed it, emptied the trash and used DU to erase that external drive in ready for the next try.
DU Help files are short and pretty clear. What did I do wrong? Can someone please give me a procedure I can succeed with?
TIA

Don't make a disc image. You cannot boot from one and they can be finicky. They are not what you want. Instead you want to clone your hard drive to an external Firewire hard drive. It's done as follows:
How to Clone Using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Erase tab in the DU main window. Set the format type to Mac OS Extended (journaled, if available) and click on the Erase button. This step can be skipped if the destination has already been freshly erased.
4. Click on the Restore tab in the DU main window.
5. Select the destination volume from the left side list and drag it to the Destination entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the drive to which you will restore or backup.
Source means the drive you are restoring from or backing up.

Acronis True Image Backup/Restore

Had my 3000 K100 for about a month now - working fine.
Like many others, the one key restore feature, 20 GB "c" drive, hidden partitions all are a bit confusing to me.
I use Acronis True Image to create emergency boot disks, and have an external drive that I use to make an image of my c and d drives. I do a full backup at least once a week. So, I really don't have to rely on on the built in Lenovo restore features.
Is there a way to just "turn it off"? Then I could make my c drive bigger - and not worry about how it would affect the one key restore features, base backups, etc.

About disk images

How do disk images work?
When you select a size for a disk image in Disk Utility does it always take up that much space or is that just the limit?
What's the difference between sparse and read/write encrypted disk image?
Can either of these formats be opened in Windows, including non-encrypted ones?
Thanks

1. When you set a size for a disk image that is the amount of space reserved for the image file. It will take up slightly more than that on a hard drive because of the directory overhead. You can store slightly less than the reserved space also due to directory overhead.
2. A sparse image, unlike a regular disk image, is created with an allocated maximum storage space but will occupy less space on the hard drive. The size of the image file will grow as more data are "written" to the image file. When File Vault creates an encrypted Home folder it does this be moving the Home folder to an encrypted sparseimage disc. Thus, a File Vault protected Home folder can increase in size to accommodate new files.
3. An encrypted disk image is just that. A disk image that is encrypted and requires a password for access to its contents. A read/write disk image is one on which you can add or remove content. A read-only image is one that once you have written to it you cannot change it.
4. Mac formatted devices (including disk images) cannot be read on PCs without special software. However, a standard disk image that is not restricted to only the Mac disk format will contain alternative filesystems that are readable on PCs.
Open Disk Utility and select Disk Utility Help from the Help menu. Search for references to disk images for more complete information.

Noob question about HDR images

hi everybody! i am reading this book about photoshop hoping to understand a lot more than i already know about pixels and colors and image dinamics and such..i got to the chapter about HDR images and here's what i dont get. as i understand, given a HDR image it has 32 bit depth meaning its file contains much more information about contrast and brightness than any existing monitor can output, so when u open it in photoshop u will never see its true quality. my question is( and i admit it may seem pointless to some, but i am committed to understand the cause and purpose), when converting it to 8 or 16 bit depth this window pops up asking me to tweak gamma, exposure, shadows and highlights, etc., but why is this linked to the conversion process? why not simply convert it, maintain the same appearance as before and then if needed manually adjust using all the image controls from the photoshop menus? i have CS6, if that matters.

I don't know if this will help, but I've heard about HDR monitors (still very expensive), which supposedly very accurately display the HDR values. If you hang one on the wall in your house, people might think it's a window, since it is literally a source of light, in the same way a window to the outside world is.
Possibly the most surprising use of HDR imagery is in 3D apps where global illumination models are used. HDR imagery literally is the only source of light for these images. There are no lights in the scene, only HDR imagery. This is because of the great dynamic range of HDR.
A more practical (to me) use of HDR is when resurrecting antique images. If you scan multiple exposures from old prints, then create HDR, sculpting values in 16-bit becomes a very powerful tool, only due to the HDR value range.
Photoshop, although it can edit very well in 16-bit, can only show 8-bit representations of HDR imagery, since almost all monitors are 8-bits per channel. Because of the monitors, we can only see a small part of what is actually present in the HDR file.
I've never done it, but I imagine that if we all had HDR monitors, we'd need to wear protective glasses (like you wear driving in your car when the sun is out) most of the time to do our work. :+)

Recovery Software for Disk Image Backup on External Drive

Hello. I am currently running OSX Yosemite on a mid-2010 Macbook Pro. However, before I upgraded from OSX Maverick I installed a SSD as a boot drive and moved my original Toshiba HDD to the optical bay for media storage. Before the installation, I purchased a LaCie 1TB external hard drive, formatted it, then dragged the entire Toshiba HDD image from the desktop to the external HD. That image is visible on the external HD but is inaccessible by Disk Utility, whether I use it from the HD, the SSD, or the Installation DVD. All scans and attempts to mount and open the image fail. I realize now I made a mistake by not cloning the Toshiba HDD onto the external HD before starting but the image size (on the external HD) is 187GB, which corresponds with a somewhat compressed ~220GB (the original size of the Toshiba HDD). Therefore, it seems as though the files are present and intact, albeit currently inaccessible.
Is there any way to recover the files from the disk image, i.e. via Data Recovery Software such as Data Rescue 4, Stellar Phoenix or R-Studio? Alternately, could I use the same software to recover the now deleted files from the wiped and reformatted Toshiba HDD? I'm having trouble accepting that the 187GB of data on the external drive are really gone, as it represents over a decade of media collection and contains many irreplaceable files. I'm hoping there is something that can be done before spending a lot of money on clean room data recovery services. Please help!!!
Thank you in advance as any and all advice is very much appreciated.

General File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive. Two free alternatives are Disk Drill and TestDisk. Look for them and demos at MacUpdate or CNET Downloads.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.
Also visit The XLab FAQs and read the FAQ on Data Recovery.

Time Machine encrypted disk image backup?

When Time Machine backs up my hard drive, it backs up a password-protected disk image as an open folder. Is there a way to back up the disk image without Time Machine opening it up?

I've played around with this a little. As best I can tell, when cloning an entire HD volume both CCC and SuperDuper will always copy an image file (.dmg, .sparsebundle, etc) that resides that on that HD, whether or not that file's disk image is mounted at the time. However the contents of the mounted disk image volume will not be copied separately, and so If the disk image is encrypted, no unencrypted content will get transferred this way. However as mentioned in the SuperDuper link above, it's better to unmount the image in any event, in order to ensure that the underlying .dmg or .sparsebundle file gets copied faithfully.
If you want to copy the contents of a mounted disk image with CCC or SuperDuper, you can do so as a completely separate procedure from copying the HD. If you first mount the image (giving a password if it was encrypted), that mounted image will appear as an independent volume in the "source list" of CCC or SuperDuper, and you can choose that volume as a source for the copy procedure. You would need to designate a different target volume as well, so as not to overwrite your HD clone. If the disk image was encrypted and you deliberately copy its mounted image separately in this fashion, the resulting files on the target will not be encrypted.
