Ive got a dmg file that the disk utility corrupted the header (from what i can gather) on a ‘check image for restore’ operation.
Attempting to mount this normally gives me a ‘corrupt image’ message.
When opening the file in DD with this attach images function, it seems like its attaching the image, but nothing happens. DD just drops me back in the disk list with no error, success, or image showing up in the list.
I checked the DD log, and there is no message relating to this attempted mount.
PS.Its a LARGE HFS+ dmg made with disk utility (compressed image) of a 3tb partition. The file is a .dmg and a .dmgpart each just about 1tb each.
If you reveal all hidden items in the disk list, the DMG is still not there in Disk Drill, isn’t it? If so, then the disk image seems to be too damaged to be mounted, and even Disk Drill can’t intercept the error message. If the image was not compressed, Disk Drill would be able to mount it in any way. Try fixing your DMG according to your Mac’s recommendation.
