Resolved HELP: Cannot restore DMG image stored on NTFS disk!

[Thor774]

Hello. My MacBook Pro has OSX Lion on it.

I have created a DMG image of my starting volume using Disk Utility. The image was saved on an NTFS formatted external USB disk. I used Paragon NTFS for Mac to activate writing on NTFS partitions. The image was created, tested and it mounted fine. It's size is 105GB.

I have restarted the system and am accessing Disk Utility from the recovery partition that OSX Lion creates. Disk Utility can see the NTFS disk and I can choose the DMG image as source and the partition on the internal hard disk as a target without problems but when I press the restore button and the Image scan process is going to start I just get an error that says "Unabke to scan Mac-OSX HD. Resource busy". When I try the SCAN BEFORE RESTORE command on Disk Utility on the image I am getting "Unable to scan MAC IMAGE.DMG (Not such file or directory)".

I have already erased my startup disk and really need to get this image back in place. It is the only backup I have of my data.

Any help is greatly appreciated!

It is probably due to the DMG being stored on an NTFS drive, even though Mac OS X can read from them.
What if you just reinstall Mac OS X without restoring and restore from the DMG later?

And if you get your Mac running, think about using CarbonCopyCloner or SuperDuper! to make a bootable backup to an external HDD (properly formatted*), as using one file (DMG) to store all your files is not a secure backup method, as one file can get corrupt.

Its most likely an NTFS issue. Not to be a jerk but its never a good idea to put mission critical Mac data on an NTFS share or disk.

Damn, I never get the notification mails from the forum. Sorry for the delay in answering.

You were all correct. Moving the dmg file to a Mac formatted hard disk was the answer, but I ended up reinstalling OSX and all my programs anyway and copying just data back from my image as there were some quirks on my actual installation.

I still think that if the OS states that it supports reading from a file system it should not have any problems at any level. I did not see or find any warning about the impossibility of disk utility to read from an image located on an NTFS formatted disk.
